All MCQ Questions with Answers and Explanations
Question 1: How many of the following statements are correct? (1) In demographic transition, a decline in mortality may occur before a decline in birth rates. (2) Low fertility and increasing life expectancy can increase ageing in the long run. (3) Demographic dividend is a permanent stage because the working-age population always remains of working age. (4) Migration can change both the total population and the age-sex structure of a region.
Correct Answer:
B
— Only three
Explanation:
Statement 1 is correct — in demographic transition, a decline in mortality often occurs before a broad decline in birth rates. Statement 2 is correct — low fertility can reduce the young base, while increasing life expectancy can increase the proportion of the elderly population. Statement 3 is incorrect — demographic dividend is not a permanent stage. The working-age group ages over time and old-age dependency may eventually increase. Statement 4 is correct — selective migration can change both age and sex structure. Hence, three statements are correct.
Question 2: In a state, general population density is low, but the proportion of cultivable land is also very low and irrigation availability is limited. Which of the following conclusions is most appropriate?
Correct Answer:
D
— General population density is not a complete measure of resource pressure; factors such as available agricultural land and water must also be considered.
Explanation:
General population density is based on total area. If a state has a large total area but very little cultivable land, general density may underestimate the actual pressure on available agricultural resources. Therefore, factors such as agricultural land and water availability must also be considered.
Question 3: Which of the following situations best explains the economic significance of India's regional demographic disparity?
Correct Answer:
A
— States where the working-age population is increasing may experience greater labour availability, while ageing states may face different challenges related to productivity, health, and social security.
Explanation:
Since the stages of demographic transition differ across states, their economic and social policy requirements may also differ. Relatively young states may need greater focus on employment and human capital, while ageing states may need greater attention to health, social security, care, and productivity.
Question 4: How many of the following statements are correct? (1) The effect of a decline in the total fertility rate on the total population does not necessarily appear immediately. (2) If net migration is positive, total population can increase even while natural growth remains negative. (3) When the working-age population is large, a demographic dividend is automatically assured. (4) Increasing life expectancy and low fertility can increase the pressure of ageing in the long run.
Correct Answer:
C
— Only three
Explanation:
Statement 1 is correct. Due to population momentum and the existing age structure, the effect of a decline in the fertility rate on the total population may appear after some time. Statement 2 is correct. Positive net migration can compensate for natural population decline and increase the total population. Statement 3 is incorrect. A large working-age population is only a potential opportunity. Conditions such as education, health, skills, employment, female labour force participation, and productivity are also necessary. Statement 4 is correct. Low fertility can reduce the young base, while increasing life expectancy can increase the proportion of the elderly population. Hence, three statements are correct.
Question 5: In a city, the proportion of the elderly population is increasing, while the young population is declining. The city administration makes public transport, housing, healthcare, and public spaces elderly-friendly and also starts reskilling programmes for older people. Which of the following conclusions is most appropriate?
Correct Answer:
D
— The policy views social security, health, urban planning, and the economic participation of older people through an integrated approach.
Explanation:
Ageing is not merely a pension issue. Elder-friendly transport and housing, healthcare, public spaces, and reskilling can improve the quality of life of older people and, where possible, enhance their economic and social participation.
Question 6: In a state, outmigration of young women is increasing. At the same time, the total fertility rate is declining. Which of the following combined effects is possible?
Correct Answer:
B
— Both the current age-sex structure and the future birth base may be affected.
Explanation:
Selective outmigration of young women can affect the working-age female population and the age-sex structure. At the same time, low fertility can reduce the size of future young generations. Together, the two processes can affect the future demographic structure of the source region.
Question 7: Which of the following options best represents the limitations of demographic indicators?
Correct Answer:
C
— Any single indicator may reflect only one aspect of the demographic situation; for a comprehensive conclusion, age, fertility, mortality, migration, and socio-economic indicators need to be considered together.
Explanation:
Each demographic indicator measures a specific aspect. The total fertility rate is a composite indicator of fertility behaviour, the dependency ratio reflects potential age-based dependency, and the population pyramid shows age-sex structure. Therefore, no single indicator should be considered a complete representation of the entire demographic scenario.
Question 8: How many of the following statements are correct? (1) A low total fertility rate can reduce the relative share of the young population in the long run. (2) Increasing life expectancy can increase the relative share of the elderly population. (3) A large share of the working-age population can create the possibility of a demographic dividend. (4) The effects of these three processes appear at the same time and at the same pace in every country.
Correct Answer:
C
— Only three
Explanation:
Statement 1 is correct. Prolonged low fertility can make the size of new generations relatively smaller. Statement 2 is correct. Due to increasing life expectancy, more people may reach older ages, increasing the proportion of the elderly population. Statement 3 is correct. A large working-age population can create the possibility of a demographic dividend under favourable economic and social conditions. Statement 4 is incorrect. Demographic transition occurs at different times and at different speeds across countries and regions. Hence, three statements are correct.
Question 9: In a country, the share of the working-age population is still large, but the elderly population is increasing rapidly. The government focuses not only on pensions but also on long-term care, reskilling, and appropriate employment opportunities for older people. What broader idea does this approach reflect?
Correct Answer:
A
— Viewing ageing not merely as a problem of dependency, but as a multidimensional issue involving health, security, and economic participation.
Explanation:
Along with income security, health, long-term care, social participation, and, where appropriate, economic activity are also important in old age. This approach is associated with the broader concepts of active ageing and the Silver Economy.
Question 10: In the rural districts of a state, outmigration of young men is high, while in some districts the outmigration of young women for education and employment is also increasing. Which of the following analyses is most appropriate?
Correct Answer:
D
— Selective migration can affect the age-sex structure, labour availability, and future fertility patterns of the source areas.
Explanation:
When migration is selective, particular age and sex groups may migrate out in greater numbers. This can affect the sex ratio, working-age structure, and future reproductive-age population. Its impact need not be uniform across all districts.
Question 11: In a state, the total fertility rate is below the replacement level, the proportion of the elderly population is increasing, and the working-age population is still large. Which of the following conclusions is most appropriate?
Correct Answer:
C
— The state may be in a transitional situation where the current working-age opportunity coexists with future pressure from ageing.
Explanation:
Changes in population structure occur gradually. A large working-age population may provide an economic opportunity at present, while low fertility and increasing life expectancy may increase the pressure of ageing in the future.
Question 12: In a country, the total dependency ratio has declined to a very low level. Which of the following conclusions is most appropriate?
Correct Answer:
D
— The country may have an age structure favourable for a potential demographic dividend, but the actual economic benefit will depend on employment, productivity, human capital, and other socio-economic conditions.
Explanation:
A low dependency ratio generally indicates a relatively large share of the population in the working-age group and can create favourable conditions for a demographic dividend. However, demographic opportunity does not automatically translate into economic gains. Employment generation, productivity, education, skills, health, female labour force participation, and institutional conditions also matter.
Question 13: In a district, the infant mortality rate is low, but the maternal mortality ratio is relatively high. Which of the following conclusions is most appropriate?
Correct Answer:
B
— Despite improvement in infant health, separate challenges may remain in maternal health, childbirth services, and pregnancy-related care.
Explanation:
Infant mortality rate and maternal mortality ratio measure different health outcomes. Even when infant health improves in a region, challenges related to maternal nutrition, antenatal care, institutional deliveries, postnatal care, or emergency obstetric services may persist.
Question 14: The elderly population of a country increases from 8% to 14%. During the same period, the working-age population declines from 66% to 60%. Which of the following policy-response combinations would be the most comprehensive?
Correct Answer:
D
— Addressing productivity growth, health and long-term care, social security, and appropriate labour force participation together
Explanation:
Ageing is a multidimensional challenge. When the elderly population increases along with a declining proportion of the working-age population, it may be necessary to give simultaneous importance to policies related to productivity, social security, health, long-term care, and labour force participation.
Question 15: A large proportion of the working-age female population in a region is outside the labour force. The same region has a large total working-age population. Which of the following conclusions is most appropriate?
Correct Answer:
C
— Despite a large working-age population, a portion of the potential labour supply may remain underutilized.
Explanation:
The working-age population and actual participation in the labour force are two different concepts. If a large number of women are outside the labour force, the full potential economic capacity of the working-age population may not be utilized.
Question 16: Which of the following situations can partially mitigate the challenge of ageing and labour shortages in a country?
Correct Answer:
B
— Improvement in the productivity of the working-age population and appropriate participation of older people in the labour force
Explanation:
When the relative share of the working-age population declines, productivity growth can create the possibility of greater output per working person. At the same time, appropriate economic participation of willing and capable older people can contribute to labour availability.
Question 17: Which of the following statements best represents the limitation of the usefulness of a population pyramid?
Correct Answer:
B
— A population pyramid is useful for understanding age-sex structure, but by itself it cannot determine the exact fertility rate, mortality rate, or magnitude of migration.
Explanation:
A population pyramid is a useful visual tool for age and sex structure, but it cannot by itself provide precise calculations of all demographic rates. Potential patterns can be inferred from it, which need to be verified with other data.
Question 18: In a region's population, the 0–14 years age group constitutes 20%, the 15–64 years age group 68%, and the 65 years or above age group 12%. What is the approximate total dependency ratio?
Correct Answer:
B
— 47.1%
Explanation:
The dependent population consists of the 0–14 and 65+ age groups. Dependent population = 20% + 12% = 32%, Working-age population = 68%. Therefore, Total Dependency Ratio = (32 ÷ 68) × 100 ≈ 47.1%
Question 19: Which of the following statements is most appropriate regarding the interpretation of population density?
Correct Answer:
C
— Despite the same general population density, actual population pressure may differ between two areas due to differences in land quality, water availability, cultivable land, and urban infrastructure.
Explanation:
General population density indicates the ratio of total population to total area. It does not directly measure land quality, cultivable area, water availability, resource productivity, or infrastructure. Therefore, the same general density does not imply the same pressure on resources.
Question 20: Which of the following situations could be consistent with an improvement in the overall sex ratio but a decline in the child sex ratio?
Correct Answer:
B
— A change in the sex structure of older age groups, while an adverse change persists in the sex structure of the child age group
Explanation:
The overall sex ratio represents the sex structure of the entire population, whereas the child sex ratio represents the sex structure of a specific younger age group. Sex differentials in mortality, migration, and changes in age structure can affect the overall sex ratio, while the child sex ratio is more closely related to births and the sex structure in early childhood. Therefore, the direction of the two indicators can differ.
Question 21: Which of the following statements presents the most comprehensive conclusion of the entire Demography chapter?
Correct Answer:
B
— The age, sex, fertility, mortality, migration, and urbanization structure of a population changes economic opportunities and the requirements of social policy.
Explanation:
Demography is not merely the study of population numbers. Age structure affects the labour force and dependency, fertility affects future generations, mortality reflects health conditions, migration affects labour and spatial distribution, and urbanization affects services and economic activity. All these have broad implications for economic development and public policy.
Question 22: In contemporary demographic discourse, describing a country as a "country with a young population" does not by itself establish which of the following conclusions?
Correct Answer:
D
— The country will definitely achieve a demographic dividend.
Explanation:
A young population provides a potential opportunity, but conditions such as education, health, skills, employment, female labour force participation, and productivity are necessary to convert it into an actual demographic dividend. Therefore, a demographic dividend is not guaranteed merely by having a young population.
Question 23: If both outmigration of young people and a low fertility rate are present simultaneously in a region, which of the following long-term effects is more likely?
Correct Answer:
A
— The relative base of both the working-age population and future young generations in the source region may weaken.
Explanation:
Outmigration of young people can weaken the current working-age group, while low fertility can reduce the size of future young generations. Together, these processes can push the age structure of the source region towards ageing.
Question 24: Which of the following situations most clearly represents the direction from demographic dividend to ageing transition?
Correct Answer:
C
— First, youth dependency declines and the working-age population increases; later, old-age dependency begins to increase.
Explanation:
During demographic transition, youth dependency may initially decline and the relative size of the working-age population may increase. Subsequently, the same large generations begin to age, and old-age dependency may increase.
Question 25: If both the total fertility rate and infant mortality rate are declining in a country, which of the following relationships is most logical?
Correct Answer:
B
— Improvement in child survival can be one of several socio-demographic factors influencing reproductive decisions.
Explanation:
An improvement in the probability of child survival can influence families' expected number of children and reproductive decisions. However, it is only one among several factors, and no mechanical or proportional relationship between the two is necessary.
Question 26: A large number of working-age migrants arrive in a metropolitan city. Labour availability in the city's economy increases, but pressure on affordable housing, transport, and water supply also increases. This situation is the best example of which of the following conclusions?
Correct Answer:
D
— Demographic change can simultaneously generate economic opportunities and pressure on urban infrastructure.
Explanation:
Working-age migration can increase the labour force and economic activity. At the same time, demand for services such as housing, transport, water, and sanitation may also increase. Therefore, economic benefits and infrastructural pressure can coexist.
Question 27: Which of the following statements most appropriately expresses the economic challenge of increasing ageing in India?
Correct Answer:
C
— Ageing involves multiple dimensions such as health, long-term care, income security, and changes in the proportion of the working-age population.
Explanation:
Ageing is a multidimensional challenge. Changes in health, long-term care, pensions, social security, and the proportion of the working-age population can affect economic and fiscal policies.
Question 28: Which of the following situations can lead to an incorrect conclusion about the state-level demographic situation when looking at the national average?
Correct Answer:
A
— Assuming that all states are at the same stage of demographic transition based on the national average fertility rate.
Explanation:
The pace and timing of demographic transition have not been uniform across Indian states. The national average can conceal regional disparities. Therefore, state-level analysis is necessary.
Question 29: In a state, the share of the working-age population is increasing. The government improves skills, health, and female labour force participation, but employment creation remains relatively slow. Which of the following conclusions is most appropriate?
Correct Answer:
D
— Labour demand and productive employment are also necessary to convert demographic opportunity into economic gains.
Explanation:
Better skills and health improve the quality of labour, but without sufficient productive employment, the full potential of a large working-age population cannot be utilized. Therefore, demographic dividend is not merely a question of labour supply; adequate labour demand and productive employment are also necessary.
Question 30: In a country, the total fertility rate remains below the replacement level for a long period. Nevertheless, the total population continues to increase for some time. Which of the following statements most appropriately explains this situation?
Correct Answer:
B
— Population momentum due to large generations already present in the age structure can sustain total population growth for some time.
Explanation:
Due to population momentum, the total population can continue to increase for some time even after the fertility rate falls below the replacement level. This may be due to the age structure of relatively large generations born earlier and their reaching reproductive age. Therefore, a time lag is possible between the fertility rate and total population size.
Question 31: If a map shows relatively earlier fertility transition in southern and some western states of a country and the role of outmigration for employment opportunities, while relatively high fertility persists in some northern states, which of the following conclusions is most appropriate?
Correct Answer:
C
— There may be regional variation in the pace of demographic transition within the country, resulting in different timelines for demographic dividend and ageing as well.
Explanation:
In a large country like India, demographic transition does not occur at the same time everywhere. Because the pace of fertility, mortality, education, health, urbanization, and migration differs among states, the stages of working-age population, demographic dividend, and ageing may also occur at different times.
Question 32: Which of the following map-based conclusions cannot be drawn solely from a population density map?
Correct Answer:
D
— The exact total fertility rate of a region
Explanation:
A population density map indicates the spatial concentration of population in an area. However, fertility rate is a separate demographic indicator that requires specific data related to births and fertility.
Question 33: If rapid urbanization, large metropolitan centres, and continued attraction of migrants from other states are visible on a map for a particular state, which of the following demographic outcomes is most likely?
Correct Answer:
B
— The relative pressure of the working-age population and demand for services may increase in urban areas.
Explanation:
The number of working-age migrants may increase in economically attractive metropolitan areas. Along with increasing labour availability, this may also increase demand for housing, transport, water supply, and other urban services.
Question 34: On the map of India, if a candidate has to identify a region with relatively slower transition from higher population growth and high fertility towards ageing, which of the following groups would be more appropriate?
Correct Answer:
A
— Bihar and Uttar Pradesh
Explanation:
The pace of demographic transition has varied across Indian states. Bihar and Uttar Pradesh remained relatively high-fertility and high-population-growth states for a long period; therefore, their transition towards ageing has been relatively later than that of the southern states.
Question 35: Which of the following map + migration combinations best represents India's internal population mobility?
Correct Answer:
D
— Migration from major labour-sending states such as Bihar and Uttar Pradesh towards economic centres such as Maharashtra, the Delhi region, etc.
Explanation:
India has numerous economic destinations for internal migration. The outmigration of labour from states such as Bihar and Uttar Pradesh and migration to regions such as Maharashtra and Delhi for employment are among the major examples. The pattern of migration is neither unidirectional nor always permanent.
Question 36: On the map of India, which of the following groups indicates areas where low population density is more likely in contrast to high population density?
Correct Answer:
C
— High mountainous regions of the Himalayas
Explanation:
Due to altitude, difficult terrain, limited cultivable land, harsh climate, and limited infrastructure in many areas, the high Himalayan regions generally have lower population density compared to the plains.
Question 37: On the map of India, if a candidate has to identify a state where coastal location, industrial-service activities, and large urban centres together create the capacity to attract inter-state migration, which of the following options is most consistent?
Correct Answer:
B
— Maharashtra
Explanation:
Maharashtra has major economic and urban centres such as Mumbai and Pune. Due to industrial, service, and financial activities, the state has long been an important destination for employment and economic opportunities.
Question 38: On the map of India, identify the southern Indian states where fertility transition occurred relatively earlier and the pressure of population ageing may also emerge relatively earlier. Which of the following groups is most appropriate?
Correct Answer:
D
— Kerala, Tamil Nadu and Andhra Pradesh
Explanation:
In several southern Indian states, fertility transition occurred relatively earlier. The combination of low fertility and increasing life expectancy may cause the pressure of ageing to emerge relatively earlier in these states as well.
Question 39: On the map of India, if a candidate has to identify states where historically high fertility levels persisted for a relatively longer period, which of the following groups would be more appropriate?
Correct Answer:
A
— Bihar, Uttar Pradesh and Jharkhand
Explanation:
The pace and timing of demographic transition have varied across Indian states. In states such as Bihar, Uttar Pradesh, and Jharkhand, the fertility transition historically occurred relatively later. The purpose of the question is to test understanding of regional demographic patterns rather than any single current statistic.
Question 40: On the map of India, which of the following regional patterns can be most closely associated with high population density and agriculture-dominated livelihoods?
Correct Answer:
C
— The Gangetic Plain
Explanation:
The flat topography, fertile soil, availability of water, and long-developed agricultural system of the Gangetic Plain have promoted relatively high population density and agriculture-based livelihoods in the region.
Question 41: Which of the following statements best expresses the multidirectional relationship between demography, economic development, and urbanization?
Correct Answer:
A
— Changes in income, education, health, and employment can influence fertility and migration; the resulting changes in age and spatial structure can in turn affect labour, savings, consumption, and demand for urban services.
Explanation:
The relationship between demography and the economy is not one-way. Education, health, income, employment, and urbanization can influence fertility, mortality, and migration patterns. Conversely, age structure, labour force, and migration affect economic production, savings, consumption, and demand for public services.
Question 42: If there is substantial outmigration of young people from a region and the birth rate is also declining there, which of the following combined demographic effects is possible?
Correct Answer:
C
— Both the youth base and the working-age group may weaken, potentially increasing the problem of population ageing and labour availability in the future.
Explanation:
Outmigration of young people can reduce the current working-age group, while a low birth rate can also reduce the size of future young generations. The combined effect of both can increase pressure on ageing and the future labour force in the source region.
Question 43: In a country, the elderly population is increasing and the government is increasing public expenditure on elderly healthcare and pensions. If, at the same time, the proportion of the working-age population declines, which of the following statements is most appropriate?
Correct Answer:
B
— Productivity, taxation, and labour force participation may become more important for financing social security and healthcare expenditure.
Explanation:
In an ageing population, expenditure on healthcare, pensions, and long-term care may increase while the relative share of the working-age population declines. In such circumstances, productivity growth, labour force participation, revenue generation, and efficient public expenditure may become increasingly important. Ageing does not make economic growth impossible.
Question 44: In a country, low fertility reduces youth dependency and increases the share of the working-age population. After a few decades, the same country moves towards ageing. Which of the following conclusions most accurately describes this entire process?
Correct Answer:
D
— Fertility transition can change the age structure in such a way that an opportunity for a dividend arises first, followed later by increasing pressure of old-age dependency.
Explanation:
The effect of low fertility becomes visible in the age structure from generation to generation. Initially, youth dependency may decline and the relative size of the working-age group may increase. Subsequently, the same large generations grow older and old-age dependency may increase. Therefore, demographic dividend is a transitional opportunity.
Question 45: Which of the following statements most correctly represents the relationship between the population pyramid and the dependency ratio?
Correct Answer:
A
— The population pyramid provides a visual indication of the age structure, from whose base and upper portions the potential pressure of youth and old-age dependency can be estimated.
Explanation:
A population pyramid is a visual representation of age and sex structure. Its broad base may indicate a relatively large young population, while an expansion of its upper portion may indicate the significance of the elderly population. It can help estimate potential age-based dependency, but it does not itself measure actual economic dependency.
Question 46: In a city, the working-age population increases due to migration. However, formal employment is limited in the local labour market and housing costs are rising rapidly. Which of the following conclusions is most appropriate?
Correct Answer:
C
— The potential benefit of demographic opportunity will be influenced by labour-market quality and urban conditions such as affordable housing.
Explanation:
An increase in the number of working-age migrants represents an expansion of the potential labour force, but adequate employment, skills, housing, and other urban facilities are necessary to convert it into productive economic gains.
Question 47: If mainly young women and men are migrating out of a region, which of the following changes may occur even if the total population decline is relatively small?
Correct Answer:
A
— The age-sex structure may change significantly because migration is selective across age and sex groups.
Explanation:
Migration is often selective by age and sex. If young women and men migrate disproportionately, the source region may experience changes in its age-sex structure, labour availability, and potentially future fertility patterns. Such structural changes may occur even when the overall change in total population is relatively small.
Question 48: In a country, the total population is approximately stable. Nevertheless, the following changes are occurring: the proportion of the elderly population is increasing, the proportion of the working-age population is declining, and the total fertility rate remains low. Which conclusion cannot necessarily be drawn from this situation?
Correct Answer:
D
— Natural population growth in the country is definitely negative at the same time.
Explanation:
The presence of an ageing age structure is not certain proof of negative natural growth. Natural growth depends on the difference between births and deaths. From the information given, it cannot be stated with certainty that natural growth is negative.
Question 49: In a state, the relative share of the working-age population is increasing. At the same time, female education, health, and labour force participation are improving. If employment creation also keeps pace with the growth of the labour force, which of the following conclusions is most appropriate?
Correct Answer:
A
— The possibility increases of transforming the demographic structure into conditions favourable for productivity and economic growth.
Explanation:
When a large working-age population, better human capital, female labour force participation, and adequate productive employment exist together, the possibility of converting demographic opportunity into actual economic gains increases. However, this is not a permanent condition, and the pressure of ageing may increase in the future.
Question 50: In a country, the total fertility rate continuously declines, but during the same period the size of the working-age population continues to increase for some time. Which of the following statements is most accurate regarding this situation?
Correct Answer:
C
— Due to the existing age structure, previously born generations, mortality, and migration, the working-age population can continue to increase for some time.
Explanation:
The working-age population is primarily composed of generations that were born earlier and enter working age over time. Therefore, the impact of a decline in the current fertility rate does not necessarily appear immediately in the working-age population. Mortality and migration also affect its size.
Question 51: If old-age dependency increases rapidly in a country after the period of demographic dividend, which of the following policy packages would be considered the most comprehensive response?
Correct Answer:
B
— Addressing productivity, elderly health, pension reforms, care arrangements, and appropriate participation of older people in the labour force together
Explanation:
Ageing is a multidimensional challenge. When the proportion of the working-age population declines, productivity growth may become important. Along with this, attention is also required towards health, pensions, long-term care, and appropriate economic participation of willing and capable older people. Therefore, a single policy would not be sufficient.
Question 52: Which of the following situations most comprehensively represents the concept of the Silver Economy?
Correct Answer:
A
— An increase in the elderly population creates new and growing demand for healthcare, care, finance, housing, and support services.
Explanation:
The Silver Economy refers to broad economic activities associated with the needs, consumption, services, and economic participation of the elderly population. Healthcare, long-term care, financial services, housing, assistive devices, and other goods and services may form part of it.
Question 53: In a region, a high rate of urban growth is accompanied by a declining proportion of the working-age population in rural areas. If the share of the elderly population in rural areas continues to increase, which of the following is a possible long-term outcome?
Correct Answer:
C
— Structural pressure on labour availability and care-related needs in rural areas may increase.
Explanation:
The outmigration of the working-age population and an increase in the elderly population can reduce labour availability in rural areas. At the same time, healthcare and care-related needs for older people may increase. Therefore, pressure on both labour and social care is possible.
Question 54: If the proportion of the elderly population in a country is increasing, but a large share of older people is still economically active, which of the following statements is most appropriate?
Correct Answer:
B
— A distinction should be made between age-based dependency and actual economic dependency.
Explanation:
The age-based dependency ratio is measured by considering certain age groups as potentially dependent. Actual economic dependency may be different from this because some older people may work, earn income, or provide economic support to their families.
Question 55: The total population of a city is increasing rapidly. At the same time, the proportion of working-age migrants is increasing, but the expansion of affordable housing, public transport, and water supply in the city remains slow. Which of the following combined conclusions is most appropriate?
Correct Answer:
D
— Migration can increase economic capacity, but inadequate urban infrastructure can limit the inclusive utilization of that capacity.
Explanation:
Working-age migration can increase the labour force and economic activity in a city. However, if housing, transport, water supply, and other urban services do not expand adequately, quality of life, labour productivity, and inclusive development may be affected. Therefore, economic opportunities and urban pressures can coexist.
Question 56: In a state, the fertility rate is declining, female education is increasing, child survival prospects are improving, and women's earning capacity is also increasing. Which of the following conclusions is most appropriate?
Correct Answer:
C
— The fertility transition may reflect the combined influence of several socio-economic and demographic factors.
Explanation:
Fertility behaviour is influenced by multiple factors, including female education, child survival, age at marriage, income, employment opportunities, women's economic status, and the perceived cost and benefits of having children. Therefore, it would be inappropriate to attribute fertility decline entirely to any single factor or assume a uniform relationship between one factor and family size.
Question 57: In a country, the youth dependency ratio is declining rapidly. After a few years, old-age dependency begins to increase. If during this period the proportion of the working-age population first increases and then stabilizes, what process does this most appropriately indicate?
Correct Answer:
A
— Gradual restructuring of the dependency structure during demographic transition
Explanation:
Initially, a decline in youth dependency and a relative expansion of the working-age group can create the possibility of a demographic dividend. Later, the same large working-age generations begin to age, which can increase old-age dependency. This indicates a gradual restructuring of the age structure.
Question 58: Which of the following situations most clearly illustrates the difference between demographic dividend and jobless growth?
Correct Answer:
D
— The working-age population increases, but adequate productive employment is not created and a large number of workers remain underemployed.
Explanation:
An increase in the working-age population is only a demographic opportunity. If the economy does not create a sufficient number of productive jobs, a large working-age population may remain unemployed, underemployed, or engaged in low-productivity employment. Therefore, demographic opportunity and actual economic dividend are not the same concept.
Question 59: In a state, the proportion of the elderly population increased from 9% to 14%. During the same period, the proportion of the working-age population declined from 64% to 60%. Which of the following statements is not necessarily correct?
Correct Answer:
B
— The natural population growth of the state has definitely become negative.
Explanation:
The increase in the elderly population and decline in the working-age population clearly indicate a change in the age structure. However, determining natural growth requires a direct comparison of births and deaths. Therefore, its becoming negative cannot be concluded from these figures alone.
Question 60: Which of the following statements best explains regional variation in the demographic dividend?
Correct Answer:
A
— Differences in the timing of fertility transition, education, health, employment and migration across states can cause the duration and intensity of the dividend to vary as well.
Explanation:
The demographic dividend is primarily associated with changes in the age structure, and these changes do not occur at the same pace across states. Therefore, the timing, duration and potential economic impact of the dividend may vary regionally.
Question 61: In a country, female education, female labour force participation and urbanisation are increasing. During the same period, the total fertility rate is declining. Which of the following conclusions is most scientific?
Correct Answer:
D
— Fertility transition may be the result of several interrelated socio-economic factors.
Explanation:
Several factors such as education, employment, health, urbanisation, timing of marriage, the cost of children and social norms can influence fertility behaviour. It is therefore not appropriate to consider any single variable as the sole cause.
Question 62: A state's population growth rate is higher than the national average. Which of the following conclusions can be drawn most appropriately from this fact alone?
Correct Answer:
A
— The state's population growth may be the result of a combination of natural increase and net migration.
Explanation:
Population growth is determined by the interaction of natural increase—births minus deaths—and net migration. Therefore, a state can have a relatively high population growth rate because of higher natural increase, positive net migration, or a combination of both. The population growth rate alone cannot establish that the state's fertility, birth or mortality rates are necessarily higher than the national average, nor can it determine the future size of its working-age population.
Question 63: Which of the following statements most accurately expresses the difference between a Census Town and a Statutory Town?
Correct Answer:
A
— A Statutory Town is based on legal status, whereas a Census Town may be identified on the basis of certain prescribed demographic and occupational criteria.
Explanation:
The fundamental basis of a Statutory Town is its statutory or administrative status. For a Census Town, criteria such as population, population density and the proportion engaged in non-agricultural main work are considered as demographic-occupational criteria.
Question 64: Which of the following statements most accurately distinguishes between the Maternal Mortality Ratio and the Maternal Mortality Rate?
Correct Answer:
C
— The Maternal Mortality Ratio relates maternal deaths to the number of live births, whereas the Maternal Mortality Rate relates maternal deaths to the population or person-years lived by women of reproductive age.
Explanation:
The Maternal Mortality Ratio (MMR) is the number of maternal deaths per 100,000 live births. In contrast, the Maternal Mortality Rate relates maternal deaths to women of reproductive age and is generally expressed using the population or person-years lived by women of reproductive age as the denominator. Thus, the two indicators differ primarily in their denominators and interpretation.
Question 65: Which of the following statements is most accurate regarding the relationship between the total fertility rate and the replacement level?
Correct Answer:
A
— When the total fertility rate is below the replacement level, generational replacement may become difficult in the long run, but this does not necessarily mean an immediate decline in the total population.
Explanation:
The replacement level is related to the long-term replacement of generations. If the total fertility rate remains below this level for a long period, successive generations may be relatively smaller. However, due to population momentum, age structure and migration, the impact on the total population does not occur immediately.
Question 66: If the crude birth rate is declining in a country and, at the same time, the relative share of women of reproductive age in the total population is also declining, which of the following conclusions should be drawn most cautiously?
Correct Answer:
D
— Some part of the decline in the crude birth rate may also be related to changes in the age structure of the population.
Explanation:
The crude birth rate has the total population as its denominator. Therefore, a decline in the relative share of women of reproductive age in the total population can affect the number of births and the crude birth rate, even if the change in age-specific fertility behaviour is not equally large. Therefore, a decline in the crude birth rate alone cannot be used to infer a decline in the total fertility rate in the same proportion.
Question 67: In a state, the proportion of the working-age population increased from 64% to 70%, while the total dependency ratio declined from 56% to 43%. Which of the following conclusions is most appropriate?
Correct Answer:
A
— The state may have developed a favourable age-structural condition for a demographic dividend.
Explanation:
An increase in the working-age population and a decline in the dependency ratio may indicate a favourable condition for a demographic opportunity. However, without employment, skills, health and productivity, this does not automatically become an economic dividend.
Question 68: If the elderly population is increasing in a country, but the economic activity of the elderly is also increasing, which of the following conclusions is most appropriate?
Correct Answer:
B
— Age-based dependency may increase, while actual economic dependency does not necessarily increase in the same proportion.
Explanation:
Age-based dependency is a statistical concept based on age groups. If some elderly people are working, actual economic dependency may be lower than the age-based ratio. Nevertheless, the need for healthcare and social security may continue.
Question 69: In a state, the proportion of the elderly population is increasing, but the productivity of the working-age population is also improving rapidly. Which of the following conclusions is most appropriate?
Correct Answer:
A
— An increase in productivity can partially offset some of the economic pressures associated with ageing.
Explanation:
An increase in the elderly population can raise the demand for social security and care. However, if the per capita productivity of the working-age population increases, greater economic output may be possible from a relatively smaller working-age group.
Question 70: Which of the following statements best expresses the potential relationship between demographic dividend and regional migration in India?
Correct Answer:
B
— Differences in the availability of the working-age population and employment opportunities across states can influence labour migration.
Explanation:
The supply of labour and demand for employment are not uniform across states. Therefore, differences between demographic structure and economic opportunities can influence inter-state migration.
Question 71: A state's total population growth rate is higher than the national average. Which of the following conclusions is not necessarily correct?
Correct Answer:
D
— The state's total fertility rate will definitely be higher than the national average.
Explanation:
Total population growth is influenced by both natural increase and net migration. Therefore, despite high population growth, it is not necessary that the total fertility rate be higher than the national average.
Question 72: In India, a state's total fertility rate is higher than the national average. Which of the following conclusions cannot be drawn from this fact alone?
Correct Answer:
D
— The state's per capita income will definitely be lower than the national average.
Explanation:
A high total fertility rate can provide indications about population structure and future demographic direction, but it cannot lead to a definite conclusion about per capita income. Income is influenced by productivity, structural transformation, urbanisation, employment and other economic factors.
Question 73: Which of the following situations can simultaneously reflect a current demographic opportunity and increasing ageing pressure in the future in a state?
Correct Answer:
A
— A large share of the working-age population, low fertility and increasing life expectancy
Explanation:
A large share of the working-age population can currently provide a favourable age structure and a potential demographic opportunity. However, if fertility is low and life expectancy is increasing, this same structure can gradually transform into a growing proportion of the elderly population, increasing old-age dependency and pressure on social security.
Question 74: In the context of India, which of the following statements best reflects the heterogeneity of demographic transition among states?
Correct Answer:
C
— The pace of demographic transition may differ across states due to different levels of fertility, mortality, education and health conditions.
Explanation:
In India, states have transitioned towards low fertility and low mortality at different times. Education, health, women's empowerment, urbanisation, income and social conditions influence the pace of this transition.
Question 75: Which of the following situations can explain both a decline in youth dependency and an increase in old-age dependency in a country?
Correct Answer:
A
— Persistently low fertility and increasing life expectancy
Explanation:
Low fertility can reduce the relative share of the child population, thereby reducing youth dependency. On the other hand, increasing life expectancy can increase the share of the elderly population and raise old-age dependency.
Question 76: In a country, the mortality rate is declining, life expectancy is increasing and the share of older age groups is increasing. Which of the following conclusions cannot be drawn from only these three facts?
Correct Answer:
C
— The total fertility rate is definitely below the replacement level.
Explanation:
The given facts allow conclusions about mortality patterns and ageing, but the exact level of the total fertility rate cannot be determined. Ageing can also result from the combined effect of several factors.
Question 77: Which of the following statements correctly distinguishes between the population growth rate and the amount of population growth?
Correct Answer:
B
— The same growth rate can produce different amounts of population growth in two countries if their initial population sizes are different.
Explanation:
The percentage growth rate represents relative change, whereas the actual amount of growth also depends on the size of the base population. For example, the same 2% growth will appear as different numbers of additional people in populations of different sizes.
Question 78: If a clear imbalance between the male and female sides is visible in a particular age group of a population pyramid, which of the following factors could be a possible explanation?
Correct Answer:
A
— Selective migration
Explanation:
Selective migration can affect a specific age and sex group more than another group. In addition, mortality, war or other social circumstances can also create imbalances in the age-sex structure.
Question 79: Which of the following statements best illustrates the difference between the Gross Reproduction Rate and the Net Reproduction Rate?
Correct Answer:
B
— The Net Reproduction Rate takes into account the survival probability of female offspring, whereas the Gross Reproduction Rate does not include this survival.
Explanation:
The Gross Reproduction Rate considers the potential number of daughters born to a woman during the reproductive period, whereas the Net Reproduction Rate also takes into account the survival of daughters. Therefore, the Net Reproduction Rate may be more useful in analysing generational replacement.
Question 80: If both the birth rate and total fertility rate are declining in a country, which of the following statements should be accepted with greater caution?
Correct Answer:
C
— A decline in the total fertility rate will result in a decline in the total population in the same year by the same proportion.
Explanation:
A decline in the total fertility rate and birth rate does not necessarily appear in the total population immediately or in the same proportion. Factors such as population momentum, age structure, mortality and migration influence the timing and direction of changes in the total population.
Question 81: In a region, both the birth rate and mortality rate are declining. The birth rate is declining more rapidly than the mortality rate. Which of the following outcomes is most likely in such a situation?
Correct Answer:
D
— The pace of natural population growth may decline and the possibility of population ageing may increase in the future.
Explanation:
If the birth rate declines rapidly while the mortality rate is also declining but at a comparatively slower pace, the gap between births and deaths may narrow. In the long run, smaller younger cohorts may also shift the age structure towards ageing.
Question 82: Which of the following situations best illustrates migration-induced urban stress in a city?
Correct Answer:
C
— Migration increases rapidly, while the expansion of affordable housing, transport, water and sanitation remains relatively slow
Explanation:
Rapid migration can increase the labour force and population of a city. If basic services and housing do not expand at the same pace, urban stresses such as overcrowding, informal settlements and inadequate services may arise.
Question 83: In a country, the total fertility rate is declining along with increases in female education and female employment. Which of the following conclusions is most appropriate?
Correct Answer:
A
— Demographic change may be interrelated with broader socio-economic change.
Explanation:
Fertility behaviour can be influenced by several factors such as income, education, health, marriage-related behaviour, employment, the cost of raising children and social norms. Therefore, demographic change cannot be separated from broader socio-economic change.
Question 84: In a state, rural-to-urban migration consists mainly of young people. If employment is available mainly in low-productivity informal sectors, which of the following conclusions is most appropriate?
Correct Answer:
D
— The size of the labour force may increase, but the impact on productivity and income will depend on the quality of employment.
Explanation:
An increase in the number of young migrants may increase labour supply, but if they enter low-productivity informal employment, quantitative growth in labour does not necessarily translate into higher income or productivity. The quality of employment is decisive.
Question 85: If youth dependency is declining rapidly in a country, while the working-age population is increasing and investment in higher education and skills is also increasing at the same time, which of the following outcomes is most likely?
Correct Answer:
D
— Demographic conditions may be relatively favourable for an increase in productivity and income.
Explanation:
Declining youth dependency and an increasing working-age population provide a basis for a potential demographic dividend. Investment in education and skills can help increase the productivity of this population. Nevertheless, the actual economic benefit will depend on employment and other institutional conditions.
Question 86: In a country, the total fertility rate is continuously declining and has fallen below the replacement level. At the same time, the mortality rate is low and life expectancy is increasing. Which of the following conclusions would be least appropriate?
Correct Answer:
D
— The total population will definitely contract rapidly in the next few years.
Explanation:
Low fertility, high life expectancy and low mortality may indicate population ageing in the long run. However, due to population momentum, the total population may continue to increase for some time. Therefore, stating that there will “definitely be rapid contraction” in the near future is an excessively certain conclusion.
Question 87: Which of the following situations best illustrates the challenge of inclusive urbanisation?
Correct Answer:
D
— Economic opportunities in the city increase, but access to housing, transport and basic services remains limited for low-income groups
Explanation:
Inclusive urbanisation is not merely a question of economic growth. If economic opportunities expand but low-income groups do not have equal access to housing, transport, water, sanitation and other basic services, urbanisation can become unequal.
Question 88: In a region, the total fertility rate is declining, but the relative share of the child population does not decline immediately. Which of the following reasons can explain this?
Correct Answer:
A
— The effect of large cohorts born during earlier periods of high fertility may persist for some time in the age structure.
Explanation:
The current child population is not determined only by the current fertility rate; the effect of large cohorts born in previous years also persists. Therefore, changes in the age structure occur gradually.
Question 89: If the working-age population in a city increases rapidly due to migration, which of the following outcomes is not automatically ensured?
Correct Answer:
C
— Per capita income will necessarily increase.
Explanation:
Migration may increase labour supply and demand for housing and may put pressure on services. However, an increase in per capita income will depend on productivity, quality of employment, capital, skills and local economic conditions.
Question 90: Which of the following situations could be consistent with a decline in the total dependency ratio but an increase in the old-age dependency ratio in a region?
Correct Answer:
A
— A sharp decline in child dependency, while the increase in old-age dependency is smaller than it
Explanation:
The total dependency ratio is determined by the combined effect of child and old-age dependency. If the decline in child dependency is greater than the increase in old-age dependency, the total dependency ratio may decline even though old-age dependency increases.
Question 91: In a country, the total population is stable, but at the same time a large number of people are moving from rural areas to cities. Which of the following conclusions is most appropriate?
Correct Answer:
D
— Even while the total population remains stable, the spatial and occupational distribution of the country's population may change.
Explanation:
Even when the change in the size of the total population is zero, its internal distribution can change. Rural–urban migration can increase the population, labour force and demand for services in cities, while changing the age and labour structure of the source areas.
Question 92: If a country experiences a rapid decline in the mortality rate, but the birth rate remains high for a long period, which of the following outcomes is most likely in the context of demographic transition?
Correct Answer:
C
— Acceleration in natural population growth
Explanation:
When mortality declines rapidly while the birth rate remains relatively high, the gap between births and deaths may widen. This leads to an increase in the rate of natural population growth. Such a pattern is characteristic of a phase of demographic transition in which mortality declines before fertility declines substantially.
Question 93: Which of the following conclusions is most appropriate when the share of the working-age population in a state is increasing rapidly, but female labour force participation is low and a large number of young people are engaged in informal and temporary employment?
Correct Answer:
B
— The state has a demographic opportunity, but converting it into actual economic gains may be constrained by labour-market, skill and institutional barriers.
Explanation:
An increasing share of the working-age population can create a demographic opportunity, but it does not automatically translate into an economic dividend. Female labour force participation, skills, quality of employment, productivity and the institutional capacity of the labour market are important in converting this opportunity into actual economic gains. Therefore, a demographic opportunity exists here, but its economic realisation may be limited.
Question 94: Which of the following statements correctly expresses the fundamental difference between the Crude Birth Rate and the General Fertility Rate?
Correct Answer:
B
— The denominator of the Crude Birth Rate relates to the total population, whereas the denominator of the General Fertility Rate relates to women of reproductive age.
Explanation:
The Crude Birth Rate expresses the number of live births relative to the total population, generally using the mid-year population as the denominator. The General Fertility Rate uses the number of women of reproductive age, generally 15–49 years, as its denominator. Thus, the two indicators differ fundamentally in their denominator.
Question 95: Which of the following statements is the most appropriate regarding the Silver Economy?
Correct Answer:
C
— Broad economic activities arising from the needs, consumption, savings, services, and economic participation of the elderly population may form part of it.
Explanation:
The Silver Economy is a broad concept covering economic activities associated with the needs, consumption, assets, services, and economic participation of older persons. It may include healthcare, care services, housing, financial services, assistive devices, leisure, education, reskilling, and other sectors.
Question 96: The share of the elderly population is increasing in a city. The city administration improves healthcare services, walkable public spaces, and public transport for the elderly. This approach is primarily associated with which concept?
Correct Answer:
A
— Age-friendly urbanization
Explanation:
Age-friendly urbanization involves designing urban environments and services according to the needs of older persons. It can include accessible transport, walkable public spaces, healthcare services, suitable housing, safety, and opportunities for social participation.
Question 97: Which of the following combinations is broadly associated with Indian states where the fertility transition occurred relatively earlier?
Correct Answer:
A
— Relatively low fertility, relatively high life expectancy, and relatively earlier emergence of population-ageing pressures
Explanation:
States where fertility transition occurred relatively earlier generally have lower fertility and a more advanced stage of demographic transition. Such states may also experience population ageing pressures relatively earlier because of sustained low fertility and improvements in survival and longevity. However, the exact demographic pattern varies across states.
Question 98: Which of the following statements most appropriately expresses the difference between a Census and a Sample Survey?
Correct Answer:
C
— A Census broadly attempts to enumerate the entire target population, whereas a Sample Survey collects information from a selected part of the population and can provide statistical estimates about the entire population.
Explanation:
A Census attempts to enumerate all units of the defined target population, whereas a Sample Survey collects information from a selected sample and uses the resulting data to estimate characteristics of the broader population.
Question 99: If the base of a country's population pyramid continuously becomes narrower, while the middle and upper age groups become relatively wider, which of the following conclusions is the most appropriate?
Correct Answer:
D
— The population may be moving towards ageing due to sustained low fertility.
Explanation:
The base of a population pyramid mainly represents younger age groups. A narrowing base can indicate sustained low fertility, while a relatively wider middle and upper age structure can indicate an increasing share of older age groups. Together, these changes may signal population ageing.
Question 100: If the Maternal Mortality Ratio declines in a country, which of the following conclusions is the most appropriate?
Correct Answer:
D
— It may indicate a reduction in the risk of maternal death associated with pregnancy, childbirth, and the postpartum period.
Explanation:
A decline in the Maternal Mortality Ratio may indicate improvements in maternal healthcare, antenatal care, skilled birth attendance, institutional delivery, emergency obstetric services, and related conditions. However, it does not by itself establish a corresponding change in other demographic indicators.
Question 101: Which of the following statements is correct regarding the Total Fertility Rate?
Correct Answer:
D
— Based on current age-specific fertility rates, it estimates the potential average number of children a hypothetical woman would have over her reproductive lifetime.
Explanation:
The Total Fertility Rate aggregates age-specific fertility rates across the reproductive age groups. It does not mean that any particular actual woman has given birth to that number of children. Rather, it represents the potential average number of children a hypothetical woman would have if the prevailing age-specific fertility rates remained unchanged.
Question 102: In a country, the number of women aged 15–49 years is 5 lakh and the number of live births in one year is 25,000. What is the General Fertility Rate?
Correct Answer:
A
— 50 per 1,000 women
Explanation:
The General Fertility Rate (GFR) measures the number of live births in a year per 1,000 women of reproductive age, usually defined as women aged 15–49 years. It is calculated as GFR = (Number of live births ÷ Number of women aged 15–49 years) × 1,000. Here, the number of live births is 25,000 and the number of women aged 15–49 years is 5,00,000. Therefore, GFR = (25,000 ÷ 5,00,000) × 1,000 = 50 per 1,000 women aged 15–49 years. Hence, A. 50 per 1,000 women is the correct answer.
Question 103: Which of the following statements correctly represents the fundamental difference between the Maternal Mortality Ratio and the Infant Mortality Rate?
Correct Answer:
C
— The Maternal Mortality Ratio is generally expressed per 100,000 live births, whereas the Infant Mortality Rate is expressed per 1,000 live births.
Explanation:
The Maternal Mortality Ratio is generally expressed as maternal deaths per 100,000 live births, whereas the Infant Mortality Rate expresses deaths of infants below one year of age per 1,000 live births.
Question 104: In a district, the total population is 10 lakh, comprising 5.2 lakh males and 4.8 lakh females. If there are 52,000 boys and 46,800 girls in the 0–6 years age group, which of the following conclusions is correct?
Correct Answer:
A
— The general sex ratio is higher than the child sex ratio.
Explanation:
The general sex ratio is calculated as the number of females per 1,000 males, while the child sex ratio is calculated as the number of girls aged 0–6 years per 1,000 boys of the same age group. Here, the general sex ratio = (4,80,000 ÷ 5,20,000) × 1,000 ≈ 923 females per 1,000 males, whereas the child sex ratio = (46,800 ÷ 52,000) × 1,000 = 900 girls per 1,000 boys. Since 923 is higher than 900, the general sex ratio is higher than the child sex ratio. Therefore, A. The general sex ratio is higher than the child sex ratio is the correct answer.
Question 105: Which of the following combinations is correct regarding the classification of a place as a Census Town in the Census of India?
Correct Answer:
B
— A minimum population of 5,000, at least 75% of the male main working population engaged in non-agricultural activities, and a population density of at least 400 persons per square kilometre are considered together as criteria.
Explanation:
Under the Census criteria, a Census Town must satisfy the prescribed combination of demographic and occupational conditions: a minimum population of 5,000, population density of at least 400 persons per square kilometre, and at least 75% of the male main working population engaged in non-agricultural activities.
Question 106: In the Census of India, which of the following is the defining basis for classifying a place as a Statutory Town?
Correct Answer:
A
— It has been legally notified as an urban local body or has been accorded statutory urban status under the relevant law.
Explanation:
A Statutory Town is a place that has been notified under the relevant law of the State or Union Territory as an urban local body, such as a municipality, municipal corporation, municipal council, nagar panchayat, or another statutory urban authority. The demographic and occupational criteria in options B–D are associated with the identification of Census Towns rather than Statutory Towns.
Question 107: Which of the following pairs is correct?
Correct Answer:
C
— Infant Mortality Rate — Deaths of children below one year of age per 1,000 live births
Explanation:
Infant Mortality Rate expresses the number of deaths of infants below one year of age per 1,000 live births. Maternal Mortality Ratio is generally expressed as maternal deaths per 100,000 live births.
Question 108: In a country, the number of women aged 15–49 years is 2,00,000 and the number of live births in one year is 8,000. Which of the following is correct regarding the General Fertility Rate?
Correct Answer:
B
— It represents live births relative to women of reproductive age.
Explanation:
The denominator of the General Fertility Rate is the number of women of reproductive age, generally 15–49 years, rather than the total population. GFR should be distinguished from TFR, which is derived from age-specific fertility rates and represents the potential average number of children of a hypothetical woman under current fertility conditions.
Question 109: In a population, the child age group constitutes 24%, the working-age group 64%, and the elderly age group 12%. What would be the approximate age-based total dependency ratio?
Correct Answer:
D
— 56.25%
Explanation:
The age-based total dependency ratio measures the number of people in the dependent age groups (children and elderly) for every 100 people in the working-age group. It is calculated as Total Dependency Ratio = [(Child population + Elderly population) ÷ Working-age population] × 100. Here, the child population is 24%, the elderly population is 12%, and the working-age population is 64%. Therefore, Total Dependency Ratio = [(24 + 12) ÷ 64] × 100 = (36 ÷ 64) × 100 = 56.25%. Thus, there are approximately 56 dependent persons for every 100 working-age persons, making D. 56.25% the correct answer.
Question 110: The total population of a region is 12 lakh and its area is 6,000 square kilometres. What is the general population density?
Correct Answer:
A
— 200 persons per square kilometre
Explanation:
Population density refers to the average number of people living per unit area of land. It is calculated by dividing the total population by the total area. Here, the total population is 12 lakh (12,00,000) and the total area is 6,000 square kilometres. Therefore, Population Density = 12,00,000 ÷ 6,000 = 200 persons per square kilometre. Hence, the general population density of the region is 200 persons per square kilometre, making A. 200 persons per square kilometre the correct answer.
Question 111: In a district, 20,000 live births occurred during one year, and 400 infants died before completing one year of age during the same year. Based on the given data, what would be the approximate Infant Mortality Rate?
Correct Answer:
B
— 20
Explanation:
The Infant Mortality Rate (IMR) is calculated as the number of infant deaths before completing one year of age per 1,000 live births. Here, the number of infant deaths is 400 and the number of live births is 20,000. Therefore, IMR = (400 ÷ 20,000) × 1,000 = 20 per 1,000 live births. Hence, the approximate Infant Mortality Rate is 20 per 1,000 live births, making B. 20 the correct answer.
Question 112: Which of the following relationships between demographic transition and economic development is the most appropriate?
Correct Answer:
C
— Demographic change and economic development can influence each other, and this relationship can operate in both directions.
Explanation:
Socio-economic changes such as education, health, income, urbanization, and changes in employment patterns can influence fertility and mortality. Conversely, changing population structures can also affect economic development through their effects on labour supply, savings, consumption, and public expenditure.
Question 113: If the proportion of the urban population in a state is increasing rapidly, which of the following conclusions cannot be drawn from this fact alone?
Correct Answer:
A
— Urban employment has definitely declined there.
Explanation:
An increase in the proportion of the urban population may indicate an accelerating urbanization process and may increase demand for housing and urban services. However, a decline in urban employment cannot be inferred from this fact alone.
Question 114: Which of the following combinations is most conducive to increasing old-age dependency pressure in a country?
Correct Answer:
D
— Low fertility, high life expectancy, and an increasing proportion of the elderly population
Explanation:
Low fertility reduces the relative size of younger generations, while high life expectancy enables more people to survive to older ages. Together, these factors can increase the relative share of the elderly population and consequently raise old-age dependency pressure.
Question 115: In a city, informal employment and unauthorized housing are also increasing along with rising migration. Which of the following conclusions is the most appropriate?
Correct Answer:
B
— Rapid population growth, if not supported by planned housing and services, can increase urban informality.
Explanation:
Rapid migration can increase labour supply and population in cities. If housing, land, transport, water, sanitation, and employment arrangements do not expand sufficiently, informal settlements and informal employment may increase.
Question 116: Which of the following situations is most consistent with a country being in a relatively advanced phase of the demographic dividend opportunity?
Correct Answer:
A
— A large working-age population, declining youth dependency, and emerging pressure from increasing old-age dependency
Explanation:
During the demographic transition, a country may reach a phase in which youth dependency has declined substantially and the working-age population constitutes a large share of the total population. At the same time, increasing longevity may gradually create greater old-age dependency pressure. This combination is consistent with a relatively advanced phase of the demographic dividend opportunity.
Question 117: A large-scale migration of young people from rural areas is taking place in a country. Which of the following effects is relatively more likely in the source rural area?
Correct Answer:
C
— A decline in the relative share of the working-age population
Explanation:
If migration consists mainly of young working-age people, their departure can reduce the relative share of the working-age population in the source area. This may increase the relative burden of children and older persons.
Question 118: If the base of a population pyramid in a region is gradually becoming narrower, which of the following changes could be a possible cause?
Correct Answer:
B
— A decline in the fertility rate
Explanation:
The base of a population pyramid represents the younger age groups. A sustained decline in fertility reduces the size of new generations and can therefore make the base of the population pyramid narrower.
Question 119: Which of the following statements is the most appropriate regarding the interpretation of the dependency ratio?
Correct Answer:
D
— It is an age-based demographic indicator of potential dependency, not a complete measure of actual economic dependency.
Explanation:
The dependency ratio generally expresses the relationship between potentially dependent age groups and the working-age population. However, it does not measure actual economic dependence. Some people in dependent age groups may be economically active, while some working-age people may not be employed.
Question 120: If infant mortality declines sharply in a country and, after some time, the Total Fertility Rate also begins to decline, which of the following relationships could be the most logical?
Correct Answer:
A
— An increase in the probability of child survival can contribute to changes in the desired number of children and reproductive behaviour of families.
Explanation:
When the probability of child survival increases, families may perceive less need to have additional births to achieve their desired number of surviving children. This is one of several socio-economic factors that can contribute to fertility decline.
Question 121: In a country, the Total Fertility Rate is below the replacement level, yet the working-age population continues to increase for the next few decades. Which of the following is the most appropriate explanation for this?
Correct Answer:
C
— Large cohorts born in the past may still be entering the working-age group.
Explanation:
Because of population momentum and the existing age structure, large cohorts born in earlier periods may continue to enter the working-age group even when current fertility is below replacement level. Therefore, the working-age population can continue to increase for some time.
Question 122: Which of the following situations would provide a stronger indication of structural urbanization in a region?
Correct Answer:
B
— Long-term growth in non-agricultural employment, urban services, and economic activities
Explanation:
Structural urbanization involves more than an increase in population. Persistent changes in employment structure, economic activities, urban services, and patterns of living provide stronger evidence of broader and structural urbanization.
Question 123: If a large number of working-age people migrate out of a region, which of the following effects is possible in the source region?
Correct Answer:
D
— Under certain circumstances, a decline in the working-age population may increase the dependency burden.
Explanation:
If migrants are predominantly of working age, their departure may reduce the relative share of the working-age population in the source region. This can increase the relative burden of children and older persons. The actual effect depends on the age-sex composition of migrants and the nature of migration.
Question 124: In a country, women's education and health have improved and the Total Fertility Rate is declining. Which of the following conclusions is the most appropriate?
Correct Answer:
A
— Social development can play a role in demographic change.
Explanation:
Social factors such as education, health, age at marriage, women's empowerment, employment opportunities, and the cost of child-rearing can influence reproductive behaviour. Therefore, demographic change is influenced by broader social and economic conditions.
Question 125: Which of the following combinations is most closely associated with the expansion of the Silver Economy?
Correct Answer:
C
— Expansion of goods, services, and employment activities related to the needs, consumption, and economic participation of the elderly population
Explanation:
The Silver Economy refers to economic activities arising from the needs, consumption, and economic participation of older persons. It may include healthcare, care services, assistive devices, housing, financial services, leisure, and other related sectors.
Question 126: In the context of demographic transition, which of the following statements is the most appropriate?
Correct Answer:
D
— The pace and pattern of demographic transition may vary across countries according to social, economic, health, and cultural conditions.
Explanation:
Demographic transition is a general analytical framework, but its pace, duration, and characteristics vary across countries. Health, education, income, social norms, public policy, and other factors can influence the pattern of demographic change.
Question 127: The total dependency ratio in a region is declining, but the old-age dependency ratio is increasing. Which of the following situations best explains this?
Correct Answer:
B
— Child dependency is declining rapidly, while old-age dependency is increasing gradually.
Explanation:
The total dependency ratio includes both child and old-age dependency. If child dependency declines sufficiently while old-age dependency increases by a smaller magnitude, the overall dependency ratio can decline even though old-age dependency itself is rising.
Question 128: Which of the following situations best illustrates the structural impact of migration on a city?
Correct Answer:
C
— Changes in the employment structure, demand for housing, and need for public services along with an increase in the labour force
Explanation:
Migration does not merely change population numbers. It can alter the labour market, types of employment, and demand for housing, transport, water, sanitation, and other urban services.
Question 129: If the relative share of the child population in a country is declining while the relative share of the elderly population is increasing, which of the following changes is most consistent with this pattern?
Correct Answer:
A
— A long-term decline in the Total Fertility Rate
Explanation:
Prolonged low fertility reduces the relative size of younger generations, which can narrow the base of the population. At the same time, the relative share of the elderly population can increase as the population ages, particularly when survival to older ages improves. Thus, a long-term decline in fertility is consistent with the observed pattern.
Question 130: A country's Total Fertility Rate declines sharply, but its total population continues to increase for a few decades. What could be the most appropriate reason for this?
Correct Answer:
B
— Due to the existing age structure and population momentum, the effect of large cohorts previously born and now entering or remaining in the reproductive-age group may persist for some time.
Explanation:
A decline in fertility does not necessarily produce an immediate decline in population. If large cohorts are entering or are already in the reproductive-age group, they may continue to generate a substantial number of births. This phenomenon is associated with population momentum.
Question 131: Which of the following statements is the most appropriate regarding urbanization?
Correct Answer:
C
— Urbanization may include changes in economic activities, employment, and the urban character of settlements along with changes in population.
Explanation:
Urbanization is not merely the process of people moving to cities. Changes in the concentration of economic activities, employment structure, settlement characteristics, and patterns of living can also be important dimensions of urbanization.
Question 132: Which of the following situations could be consistent with a decline in youth dependency but an increase in old-age dependency?
Correct Answer:
A
— A long-term decline in the birth rate and an increase in life expectancy
Explanation:
Prolonged low fertility can reduce the relative share of children, while increasing life expectancy can enable more people to survive to older ages. Therefore, youth dependency can decline while old-age dependency increases.
Question 133: Rural–urban migration has accelerated in a region. As a result, both the labour force and population in the city increase, but pressure on housing, water, and transport also increases. This example primarily illustrates what?
Correct Answer:
D
— The capacity of migration to generate economic opportunities as well as pressure on urban infrastructure
Explanation:
Migration can provide cities with additional labour and stimulate economic activity. However, rapid migration can also increase demand for housing, water, sanitation, transport, and other public services.
Question 134: Which of the following statements is correct regarding the Total Fertility Rate?
Correct Answer:
C
— A change in the Total Fertility Rate can affect future age structure and population dynamics, but its effects are neither immediate nor uniform.
Explanation:
The Total Fertility Rate is a summary measure of fertility based on age-specific fertility rates. A change in TFR can influence the size of future generations and the age structure of the population. However, its effect on total population is not immediate and is also influenced by factors such as population momentum, existing age structure, mortality, and migration.
Question 135: The proportion of the working-age population in a country has increased. However, unemployment is high, skill levels are weak, and access to healthcare services is unequal. Which of the following conclusions is the most appropriate regarding this situation?
Correct Answer:
D
— A demographic opportunity exists in the country, but complementary conditions are necessary to convert it into economic gains.
Explanation:
A larger share of the working-age population creates a potential demographic opportunity, but without adequate employment, education, skills, healthcare, investment, and appropriate economic policies, this opportunity cannot necessarily be converted into an actual economic dividend. Therefore, a favorable change in age structure alone is not sufficient.
Question 136: If the Total Fertility Rate (TFR) of a country remains below the replacement level for a prolonged period, while other demographic conditions remain broadly unchanged, which of the following outcomes is most likely?
Correct Answer:
C
— The population age structure will gradually shift towards a greater proportion of older people.
Explanation:
If fertility remains below the replacement level for a prolonged period, successive younger generations are likely to become smaller relative to previous generations. Over time, this can increase the relative share of older age groups and contribute to population ageing, particularly when life expectancy remains high or continues to increase. However, below-replacement fertility does not necessarily result in an immediate decline in total population. Population momentum, age structure and the size of existing generations can allow the population to continue growing for some time even after fertility falls below the replacement level.
Question 137: Which of the following situations is most favourable for realizing the Demographic Dividend in a country?
Correct Answer:
D
— An increase in the working-age population accompanied by improvements in skills, health and productive employment opportunities
Explanation:
A rise in the proportion of the working-age population does not automatically generate a demographic dividend. To convert a favourable age structure into sustained economic gains, a country needs adequate investment in education, health, skills and human capital, along with productive employment opportunities and effective labour force participation. Therefore, Option D represents the most favourable combination for realizing the Demographic Dividend.
Question 138: Which of the following combinations is most likely to indicate population ageing?
Correct Answer:
D
— Low fertility rate and increasing life expectancy
Explanation:
Low fertility tends to reduce the relative size of younger generations, while increasing life expectancy allows a greater proportion of people to survive to older ages. Over time, the combined effect can increase the proportion of elderly people in the population and lead to an ageing population. Therefore, low fertility and increasing life expectancy are important demographic factors associated with population ageing.
Question 139: Which of the following statements regarding the Total Fertility Rate (TFR) is correct?
Correct Answer:
C
— It represents the average number of children a woman would have over her reproductive lifetime if the prevailing age-specific fertility rates remained unchanged.
Explanation:
The Total Fertility Rate (TFR) is a period measure that summarizes the prevailing age-specific fertility rates. It represents the average number of children a woman would have over her reproductive lifetime if the age-specific fertility rates observed during the reference period remained unchanged throughout her reproductive years. It is a hypothetical measure and should not be confused with the crude birth rate, which relates the number of live births to the total population. TFR is not restricted to married women.
Question 140: Assertion (A): Viewing demographic transition merely as a time series of birth rates and death rates is an incomplete approach. Reason (R): Factors such as age structure, urbanization, education, health, employment, and social behaviour can influence the nature of demographic change and its economic and social effects.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
The Assertion is correct. Fertility and mortality are central components of demographic transition, but demographic change cannot be understood fully through birth and death rates alone. Age structure, migration, urbanization, education, health conditions, employment patterns, and social behaviour can shape demographic outcomes and determine their wider economic and social consequences. Therefore, the Reason correctly explains the Assertion.
Question 141: Assertion (A): A relatively smaller working-age population necessarily results in a decline in an economy's total productive capacity. Reason (R): Higher productivity per worker can partially offset the effects of a decline in the size of the working-age population.
Correct Answer:
D
— The Assertion is incorrect, but the Reason is correct.
Explanation:
The Assertion is incorrect because a smaller working-age population does not necessarily result in a decline in total productive capacity. Productivity growth, technological advancement, greater capital intensity, higher labour-force participation, and other factors can partly or substantially offset the effect of a smaller workforce. The Reason is correct because higher output per worker can compensate for part of the reduction in the number of workers.
Question 142: Assertion (A): Increasing working-age migration to a city may simultaneously increase both economic opportunities and urban pressures. Reason (R): Working-age migrants necessarily reduce the demand for housing, transport, water, and sanitation in the destination city.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct. Working-age migration can expand the labour supply, stimulate economic activity, and create new economic opportunities, while simultaneously increasing demand for housing, transport, water, sanitation, and other urban services. The Reason is incorrect because an increase in migrants generally adds to, rather than necessarily reduces, the demand for these services. Therefore, the correct answer is C.
Question 143: Assertion (A): To understand the effects of low fertility, looking only at the current age structure is not sufficient. Reason (R): The age structure of a population is commonly presented through the relative distribution of population across different age groups.
Correct Answer:
B
— Both the Assertion and the Reason are correct, but the Reason is not the correct explanation of the Assertion.
Explanation:
The Assertion is correct because understanding the effects of low fertility requires consideration of past fertility trends, cohort size, mortality, migration, and the likely future evolution of the age structure, rather than merely observing its present composition. The Reason is also correct because age structure is commonly expressed through the relative distribution of population across different age groups. However, this definition of age structure does not explain why examining only the current age structure is insufficient for understanding the effects of low fertility. Therefore, the Reason is not the correct explanation of the Assertion.
Question 144: Assertion (A): Rapidly growing urban population is not, by itself, evidence of inclusive urbanization. Reason (R): Along with an increase in urban population, access to services such as housing, transport, water, and sanitation may remain unequal among different socio-economic groups.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
The Assertion is correct. Urban population growth indicates demographic and spatial change, but it does not by itself establish that urbanization is inclusive. Inclusive urbanization also requires equitable access to housing, infrastructure, basic services, mobility, and economic opportunities. Therefore, the Reason correctly explains the Assertion.
Question 145: Assertion (A): An age-based dependency ratio provides a complete measure of the actual economic dependency of a population. Reason (R): Some elderly people may remain economically active, while some people in the conventional working-age group may be unemployed or economically inactive.
Correct Answer:
D
— The Assertion is incorrect, but the Reason is correct.
Explanation:
The Assertion is incorrect because the age-based dependency ratio is a demographic indicator based primarily on age categories and does not capture actual employment, income, productivity, or economic activity. The Reason is correct because some elderly people may continue to work and earn income, while some people in the conventional working-age group may be unemployed or economically inactive.
Question 146: Assertion (A): Selective out-migration of working-age people from a region may increase the ageing pressure there in the future. Reason (R): Out-migration of working-age people always reduces the absolute number of elderly persons in the source region.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct. If working-age people migrate disproportionately from a region, the relative share of elderly persons and other dependants may increase, thereby increasing ageing pressure. However, the Reason is incorrect because out-migration of working-age people does not necessarily reduce the absolute number of elderly persons. The elderly population may remain unchanged or even increase due to ageing and longer life expectancy.
Question 147: Assertion (A): A country's total population remaining approximately stable does not guarantee that its age structure will remain stable. Reason (R): Age structure is commonly represented through the relative proportions of children, working-age persons, and elderly persons in the population.
Correct Answer:
B
— Both the Assertion and the Reason are correct, but the Reason is not the correct explanation of the Assertion.
Explanation:
The Assertion is correct because total population size and age composition are different demographic characteristics; a population can remain approximately stable while its age distribution changes. The Reason is also correct because age structure is commonly expressed through the relative proportions of different age groups. However, this definition does not explain why a stable total population does not guarantee a stable age structure. Therefore, the Reason is not the correct explanation of the Assertion.
Question 148: Assertion (A): Even after the total fertility rate in a country falls below the replacement level, the working-age population may continue to increase for some time. Reason (R): Larger cohorts born during earlier periods of relatively higher fertility may subsequently enter the working-age population and contribute significantly to its size.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
The Assertion is correct. A decline in fertility does not immediately reduce the working-age population because the age structure reflects births that occurred in earlier periods. Larger cohorts born during periods of relatively higher fertility may subsequently enter the working-age group. This cohort effect can sustain or even increase the working-age population for some time despite below-replacement fertility. Therefore, the Reason correctly explains the Assertion.
Question 149: Assertion (A): The period of demographic dividend is not permanent. Reason (R): A large working-age population remains permanently within the working-age group, ensuring that the demographic dividend continues indefinitely.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct because the demographic dividend arises from a favourable but temporary age structure in which the working-age population constitutes a relatively large share and the dependency burden is comparatively low. This demographic advantage does not continue indefinitely. Over time, the working-age population itself ages and a growing proportion eventually enters older age groups, potentially increasing old-age dependency. The Reason is incorrect because a large working-age population does not remain permanently within the working-age group. Therefore, the Assertion is correct, but the Reason is incorrect. Hence, C is the correct answer.
Question 150: Assertion (A): A decline in infant mortality, by itself, necessarily leads to the beginning of fertility transition in a country. Reason (R): Fertility transition is influenced by multiple demographic, social and economic factors, including mortality decline, education, urbanisation, changing family preferences and access to contraception.
Correct Answer:
D
— The Assertion is incorrect, but the Reason is correct.
Explanation:
The Assertion is incorrect because a decline in infant mortality, by itself, does not necessarily initiate fertility transition. Although declining infant mortality can influence reproductive behaviour by improving the probability of child survival, fertility transition is a broader demographic process shaped by multiple factors. The Reason is correct because fertility transition can be influenced by several demographic, social and economic factors, including mortality decline, education, urbanisation, changing family preferences and access to contraception.
Question 151: Assertion (A): The combined situation of low fertility and increasing life expectancy can accelerate the ageing of a country's population. Reason (R): Low fertility can reduce the relative size of younger generations, while increasing life expectancy can increase the proportion of people surviving to older ages.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
Low fertility reduces the relative size of younger cohorts, thereby increasing the relative weight of older age groups in the population. At the same time, increasing life expectancy allows a larger proportion of people to survive to advanced ages. Together, these demographic changes can increase the proportion of older persons and accelerate population ageing. Therefore, both the Assertion and the Reason are correct, and the Reason correctly explains the Assertion.
Question 152: Assertion (A): The expansion of the Silver Economy can reflect the growing economic significance of an ageing population. Reason (R): Elderly people are only recipients of social assistance and generally have no significant consumption capacity or economic role.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct. The Silver Economy refers broadly to economic activities, products and services associated with the needs, preferences and consumption of older persons. An ageing population can create substantial demand for healthcare, pharmaceuticals, long-term care, assistive technologies, age-friendly housing, financial services, leisure and other goods and services. Moreover, some elderly people may remain economically active, hold assets, save, invest or provide unpaid care. Therefore, the Reason is incorrect because older persons cannot be viewed merely as passive recipients of social assistance. Hence, C is the correct answer.
Question 153: Assertion (A): A decline in the infant mortality rate can be an indicator of improvements in health and broader social conditions in a country. Reason (R): Infant mortality is influenced only by the level of school education and is not directly affected by the availability or quality of healthcare services.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct. A decline in the infant mortality rate can reflect improvements in maternal and child healthcare, neonatal care, immunization, nutrition, sanitation, safe drinking water and overall socio-economic conditions. The Reason is incorrect because infant mortality is influenced by a wide range of factors and is directly affected by the availability and quality of healthcare services. Education is also an important determinant, but it is not the sole factor. Therefore, the correct answer is C.
Question 154: Assertion (A): The combination of low fertility and high life expectancy can accelerate population ageing and increase the associated dependency burden in a country. Reason (R): Low fertility reduces the relative size of younger generations, while high life expectancy increases the likelihood that people will survive to older ages.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
The Assertion is correct. Low fertility reduces the relative share of younger age groups, while high life expectancy allows a larger proportion of the population to survive into older ages. Together, these processes can shift the age structure towards older age groups and accelerate population ageing. This may increase the demand for pensions, healthcare, long-term care and other forms of social support and may raise the old-age dependency burden. Therefore, the Reason correctly explains the Assertion.
Question 155: Assertion (A): An increase in the urban population of a region always indicates that rural–urban migration has been the principal cause of that increase. Reason (R): Urban population growth can also result from natural increase within urban areas and from the reclassification of settlements or changes in their administrative status.
Correct Answer:
D
— The Assertion is incorrect, but the Reason is correct.
Explanation:
The Assertion is incorrect because an increase in urban population does not always indicate that rural–urban migration has been the principal cause. Urban population can increase through several mechanisms, including natural increase, rural–urban migration, and the reclassification of settlements or changes in administrative boundaries. The Reason is correct because these factors can independently contribute to an increase in the officially classified urban population. Therefore, the Assertion is incorrect, while the Reason is correct. Hence, D is the correct answer.
Question 156: Assertion (A): Despite a decline in the total fertility rate in a country, its population may continue to grow for some time. Reason (R): The total fertility rate is a period measure based on the fertility rates observed during a particular period and does not directly represent the completed fertility of women who have already passed through their reproductive years.
Correct Answer:
B
— Both the Assertion and the Reason are correct, but the Reason is not the correct explanation of the Assertion.
Explanation:
The Assertion is correct. A decline in the total fertility rate does not necessarily lead to an immediate decline in population size. Population may continue to grow because of factors such as population momentum, whereby a large proportion of the population is already in or entering the reproductive-age groups. The Reason is also correct: TFR is a period measure that reflects the fertility rates prevailing during a particular period and does not directly indicate the completed number of children actually borne by a cohort of women. However, this property of TFR does not explain why population continues to grow despite declining fertility. Therefore, both statements are correct, but the Reason is not the correct explanation of the Assertion. Hence, B is the correct answer.
Question 157: Assertion (A): A low fertility rate can affect the age structure of the workforce in the long run. Reason (R): A smaller generation born today will eventually enter the working-age population, subject to survival and migration.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
Low fertility generally results in smaller birth cohorts. As these smaller cohorts age, they eventually enter the working-age population, thereby affecting its size and age composition. Consequently, persistent low fertility can influence the age structure of the workforce over the long term. The Reason correctly explains the mechanism through which low fertility can affect the future workforce. Therefore, A is the correct answer.
Question 158: Assertion (A): The status of a statutory town and the demographic size of a settlement are necessarily the same concept. Reason (R): The classification of a statutory town is based on its legal or administrative status rather than solely on its population size.
Correct Answer:
D
— The Assertion is incorrect, but the Reason is correct.
Explanation:
The Assertion is incorrect because the statutory status of a town and the demographic size of a settlement are not necessarily the same concept. A settlement's population size does not, by itself, determine whether it has statutory town status. The Reason is correct because a statutory town is identified on the basis of its legal or administrative status, such as being governed by an urban local body or another legally recognized authority. Thus, statutory classification is distinct from population size. Therefore, the Assertion is incorrect, but the Reason is correct.
Question 159: Assertion (A): Rural-to-urban migration can contribute to the growth of the population of a city. Reason (R): Migration always increases the natural growth rate of a region.
Correct Answer:
C
— The Assertion is correct, but the Reason is incorrect.
Explanation:
The Assertion is correct because rural-to-urban migration adds migrants to the population of a city and can therefore contribute to its population growth. However, the Reason is incorrect. Migration and natural increase are distinct components of population change. Natural increase is determined by the difference between births and deaths, whereas migration involves the movement of people into or out of a region. Migration does not necessarily increase the natural growth rate of a region. Therefore, the Assertion is correct, but the Reason is incorrect.________________________________________
Question 160: Assertion (A): Total Fertility Rate and Crude Birth Rate are distinct demographic indicators. Reason (R): Both Total Fertility Rate and Crude Birth Rate are widely used in demographic analysis to study population and fertility patterns.
Correct Answer:
B
— Both the Assertion and the Reason are correct, but the Reason is not the correct explanation of the Assertion.
Explanation:
The Assertion is correct because Total Fertility Rate (TFR) and Crude Birth Rate (CBR) are different demographic indicators. TFR is derived from age-specific fertility rates and estimates the average number of children a woman would have if current age-specific fertility rates remained constant. CBR, in contrast, measures live births during a given period relative to the total population, usually expressed per 1,000 population.
Question 161: Assertion (A): A long-term decline in the mortality rate in a country can alter the age structure of its population. Reason (R): A decline in mortality does not affect all age groups equally and may particularly increase survival at younger ages.
Correct Answer:
A
— Both the Assertion and the Reason are correct, and the Reason is the correct explanation of the Assertion.
Explanation:
A sustained decline in mortality can alter the age structure of a population because improvements in survival are not necessarily distributed equally across age groups. A substantial decline in infant and child mortality, for example, can increase the number of children surviving into older age groups, thereby affecting the population's age composition over time. Thus, the Assertion is correct, and the Reason correctly explains why mortality decline can alter age structure.
