Population Studies and Demography: 37 MCQs with answers

The scientific study of human populations and their changes

Demography is the scientific study of human populations — their size, composition, distribution, and changes over time.

Stage 2

In Stage 2, death rates fall while birth rates remain high, causing rapid population growth.

105 males per 100 females

Naturally, about 105 males are born for every 100 females.

True

The Demographic Transition Theory explains how countries move from high birth and death rates to low birth and death rates as they develop economically, with a fifth stage of population decline observed in some modern countries.

To analyze human populations and their changes

The correct option is B because Population Studies, or demography, specifically focuses on human populations, including their size, composition, and distribution, as well as how these factors change over time.

Analyzing human populations

Population Studies, or demography, specifically analyzes human populations, including their size, composition, and distribution.

Population Change = (Births - Deaths) + (Immigration - Emigration)

The demographic equation accurately describes how population changes through births, deaths, immigration, and emigration.

Stage 2: Early transition

Stage 2 of the Demographic Transition Theory features high birth rates and decreasing death rates, leading to rapid population growth.

The number of births per 1,000 people

The Crude Birth Rate (CBR) measures the number of live births in a year per 1,000 people in the mid-year population.

A young, fast-growing population

A broad base in an age pyramid signifies a young population with high birth rates, indicating rapid growth.

The ratio of dependents to the working-age population

The dependency ratio compares the number of dependents (ages 0-14 and 65+) to the working-age population (ages 15-64).

To show mortality rates and life expectancy

A life table provides data on mortality rates, the probability of dying, and average years remaining to live for different age groups.

To estimate fertility when birth registration is incomplete

The Child-Woman Ratio (CWR) is an indirect measure of fertility, useful when birth registration data is lacking.

An ageing population

A high Crude Death Rate (CDR) can indicate an ageing population, as older individuals tend to have higher mortality rates.

105 males for every 100 females

The natural sex ratio at birth is approximately 105 males for every 100 females, reflecting biological norms.

320,000

Population Change = (500,000 − 200,000) + (50,000 − 30,000) = 300,000 + 20,000 = 320,000.

It ignores the age structure of the population

CBR is called crude because it does not account for age structure — a country with many women of childbearing age will show a high CBR even if individual fertility is low.

Age-Specific Death Rate

ASDR tells you which age groups are dying more and is the building block for life tables and life expectancy.

It often has incomplete records in developing countries

CRS is continuous and timely but often incomplete in developing countries, which is why surveys like NFHS and DLHS fill the gaps.

A potential economic boost when working-age population exceeds dependents

The demographic dividend is a potential boost, not automatic. It requires jobs, education, healthcare, and good governance.

Constrictive — ageing and shrinking

A constrictive pyramid has a narrow base and wide top, indicating an ageing, shrinking population.

When birth registration is incomplete

CWR is an indirect fertility measure useful when birth registration is incomplete, though it is less accurate than TFR.

It summarizes the factors affecting population change.

The demographic equation summarizes the forces of population change, including births, deaths, immigration, and emigration.

ASDR adjusts for age structure by focusing on specific age groups.

ASDR improves upon CDR by providing a more precise measure of mortality that accounts for the age distribution within a population.

Stage 2: Early transition

Stage 2 is marked by high birth rates and decreasing death rates, leading to rapid population growth.

Adequate job opportunities and education.

To realize a demographic dividend, a country must create enough jobs and provide good education and skills to benefit from a larger working-age population.

CWR is useful when birth registration is incomplete.

CWR is an indirect measure of fertility that helps estimate birth rates in contexts where direct data may be lacking.

An aging population with a declining birth rate.

A constrictive population pyramid indicates an aging population with fewer young people and a declining birth rate.

It describes lower fertility levels due to social and economic factors.

'Urban infertility' refers to lower fertility levels in cities due to lifestyle choices and access to family planning, not medical infertility.

It often provides incomplete data.

In developing countries, the CRS often suffers from incomplete data due to various logistical and administrative challenges.

The right to decide freely about childbearing without discrimination.

Reproductive justice encompasses the right to make informed choices about childbearing free from discrimination, including access to necessary resources.

More dependents relative to the working-age population.

A high dependency ratio indicates that there are many dependents (young and elderly) compared to the working-age population, putting pressure on resources.

Its population is very old

An ageing country can have a high CDR even with excellent healthcare, simply because older people die more often. CDR ignores age structure.

Both A and R are true, and R correctly explains A.

CBR ignores age structure, so a large proportion of women of childbearing age inflates the rate even when individual fertility is low. R is the correct explanation of A.

67

Dependency Ratio = (30 + 10) / 60 × 100 = 40/60 × 100 ≈ 67.

It ignored technological progress, birth control, and education

Malthus underestimated technological progress (Industrial and Green Revolutions), birth control, and education, so his predictions of famine and collapse did not come true in most of the world.

It refers to lower fertility in cities due to social and economic factors

Urban infertility is a misleading name — it refers to lower fertility levels in cities due to later marriage, working women, higher costs, and better access to contraception, not a medical condition.
