Population — Practice

Question 1

Which is the most populous country in the world?

Accepted Answer

Step 1 — As of 2023, INDIA is the most populous country in the world.
  Population: ~1.43 billion.

Step 2 — Recent change.
  India overtook China in 2023. China had been the most populous country since the 1960s.
  Chinese population: ~1.41 billion (declining due to low birth rate).

✦ Answer: INDIA — 1.43 billion. Overtook China in 2023.

Question 2

Define 'population density'.

Accepted Answer

Step 1 — Define.
  Population density = number of people per unit area (typically per square kilometre).

Step 2 — India's average.
  ~464 people/km² (2024 estimate). Among the highest in the world.

Step 3 — Why it matters.
  Density determines pressure on land, water, infrastructure, jobs.
  Compare:
  - Bihar: 1,106/km² (very high density).
  - Arunachal Pradesh: 17/km² (very sparse).
  - Same country, vastly different population densities.

✦ Answer: Population density = number of people per square kilometre. India's average is ~464/km² — among the world's highest.

Question 3

What is the sex ratio? What is India's current sex ratio?

Accepted Answer

Step 1 — Define.
  Sex ratio = number of females per 1,000 males.
  Higher = more females per male = more equal.

Step 2 — India's data.
  • 2011 Census: 940 females per 1,000 males.
  • Sample surveys 2021: ~1,020 (slightly more females than males).

Step 3 — Why historically unfavourable.
  Female infanticide, prenatal sex selection (illegal but happens), gender-based nutritional gaps, cultural preferences for sons.

Step 4 — Recent improvement.
  Reflects gradual social change, government schemes (Beti Bachao Beti Padhao), stricter laws.

✦ Answer: Sex ratio = number of females per 1,000 males. India's 2011 Census: 940. Recent estimates: improving toward parity. Reflects fight against gender bias.

Question 4

What is the 'demographic dividend'?

Accepted Answer

Step 1 — Define.
  Demographic dividend = the economic opportunity that arises when a country has a large WORKING-AGE population (15-59) relative to DEPENDENT populations (children + elderly).

Step 2 — India's situation.
  Working-age (15-59): ~64% of population.
  Children (0-14): ~28%.
  Elderly (60+): ~8%.
  Ratio of working-age to dependents: high — about 2:1.
  This is FAVOURABLE for economic growth — more producers, fewer dependents.

Step 3 — Time-limited.
  India's demographic dividend lasts ~25-30 more years (until ~2050).
  After 2050, India will start ageing rapidly.

Step 4 — Why it matters.
  Countries that 'cash in' the demographic dividend (China, Korea, Japan, Singapore) saw rapid economic growth. India is currently in this window.
  Squandering the dividend = squandering generational opportunity.

✦ Answer: A period when working-age population (15-59) significantly outnumbers dependents (children + elderly). India has it now (~64% working-age). Lasts till ~2050. Provides economic opportunity if used well.

Question 5

What is a census and when was the most recent in India?

Accepted Answer

Step 1 — Define.
  Census = an official, systematic enumeration of population conducted at regular intervals. Counts every individual in the country.

Step 2 — Indian Censuses.
  India has conducted censuses every 10 years since 1872 (with rare exceptions).
  Most recent COMPLETED census: 2011.
  Census 2021: delayed by COVID-19. Partial data being released.
  Next major census: expected by 2026.

Step 3 — What's measured.
  • Total population.
  • Population by sex, age, religion, caste (limited), literacy.
  • Economic activity, housing conditions.
  • Migration patterns.
  • Disability data.

Step 4 — Use.
  • Government planning.
  • Constituency delimitation (elections).
  • Resource allocation between states.
  • Policy formulation.

✦ Answer: Census = official population enumeration every 10 years. India's last completed census: 2011. The 2021 census was delayed due to COVID-19 and is expected to be completed by 2026.

Question 6

Why is India's population distribution uneven?

Accepted Answer

Step 1 — Key factors.

(a) PHYSICAL FACTORS:
  • Water availability: Northern Plains have rivers → dense population. Deserts and dry regions sparse.
  • Soil fertility: Alluvial soil of Ganga Plain → high agricultural productivity → dense population.
  • Terrain: Mountains and forests (Arunachal Pradesh: 17/km²) hard to live in.
  • Climate: Extreme heat (Rajasthan) or cold (Ladakh) reduces population.

(b) ECONOMIC FACTORS:
  • Industrial cities: Mumbai, Bangalore, Hyderabad attract population.
  • Trade centres: Coastal cities historically grew due to maritime trade.
  • Mining regions: Jharkhand, Chhattisgarh have specific mineral-based settlements.

(c) SOCIAL/HISTORICAL FACTORS:
  • Religious significance: Varanasi, Allahabad, Amritsar attract pilgrims and permanent settlers.
  • Political centres: Delhi (capital) has the largest population.
  • Educational hubs: cities with universities attract young people.

Step 2 — Result.
  • Northern Plains (UP, Bihar, WB): 40% of population on 25% of land.
  • Himalayan, desert, NE regions: <10% of population on 25%+ of land.
  • This unevenness creates pressures: urban congestion in some areas, depopulation in others.

✦ Answer: India's population is unevenly distributed due to: (i) PHYSICAL factors — water, soil, terrain, climate; (ii) ECONOMIC factors — industries, trade, mining; (iii) SOCIAL/HISTORICAL factors — religious sites, political centres, educational hubs. Northern Plains are densest; Himalayas, deserts, NE are sparsest.

Question 7

Why did India's population grow so rapidly after 1921?

Accepted Answer

Step 1 — 1921 milestone.
  1921 was the only year (1901-1921) when India's population actually declined — due to the 1918-19 influenza pandemic.
  After 1921, population began growing rapidly.

Step 2 — Falling death rate.
  • Better medical care (vaccines, hospitals, doctors).
  • Public health (sanitation, clean water).
  • Famine relief.
  • Food security (Green Revolution from 1960s).
  Death rate fell from ~50 per 1000 (1901) to <10 per 1000 (2024).
  Life expectancy: 32 years (1947) → 70 years (2024).

Step 3 — Stable/declining birth rate.
  Birth rate fell slower than death rate. Birth rate stayed high through 1980s due to:
  • Tradition of large families.
  • Limited family planning access.
  • Low female education.
  • Need for child labour in agriculture.
  • Cultural preference for sons.

Step 4 — Growth pattern.
  • 1921-1951: 'Period of population explosion' begins. Death rate falling, birth rate high. Growth ~1.3% per year.
  • 1951-2001: Maximum growth. ~2.0-2.3% per year. Population doubled every ~35 years.
  • 2001-2024: Slowing. Now ~1.0% per year. Birth rate finally falling.

Step 5 — Demographic transition explanation.
  This rapid growth was the classic 'demographic transition' that all countries go through. Industrialised countries (UK, USA) went through it in the 19th century. India went through it in the 20th. Late starters (much of Africa) are still in it.

✦ Answer: India's population grew rapidly after 1921 because DEATH RATES FELL FASTER than BIRTH RATES. Better medicine, sanitation, food security reduced deaths. Births stayed high due to tradition and culture. Result: population growth peaked in the 1970s-90s, now slowing as birth rates also fall.

Question 8

Why does India's female literacy rate lag behind male literacy?

Accepted Answer

Step 1 — Current data.
  Male literacy: ~88% (2024 estimate).
  Female literacy: ~74% (2024 estimate).
  Gap: 14 percentage points.
  Was 20+ points in 1991. Improving but persistent.

Step 2 — Reasons for the gap.

(a) HISTORICAL DEPRIVATION:
  • Girls' education was traditionally not prioritised.
  • Girls were married young, often leaving school.
  • Education seen as 'for boys.'

(b) ECONOMIC FACTORS:
  • Girls expected to help with housework, look after siblings.
  • Limited family budget often went to boys' education.
  • Marriage expenses (dowry) prioritised over education.

(c) SOCIAL/CULTURAL FACTORS:
  • Patriarchal attitudes.
  • Concerns about safety, distance to school.
  • Religious or community resistance to girls' education in some areas.
  • Caste-based discrimination compounding gender bias.

(d) INFRASTRUCTURE FACTORS:
  • Lack of girls-only toilets in schools (a major dropout factor).
  • Distance to schools.
  • Lack of female teachers.

Step 3 — Government schemes addressing this.
  • Right to Education Act (2009).
  • Beti Bachao Beti Padhao (2015).
  • Mid-day Meals (reduces drop-out).
  • Free textbooks, uniforms for girls.
  • Sukanya Samriddhi Account (savings for girl's education).
  • Anganwadi programmes (early childhood education).

Step 4 — Regional variation.
  • Kerala female literacy: 92% (close to male).
  • Bihar female literacy: 53% (gap of 25+ points from male).
  • Reflects different state-level investment, cultural norms.

Step 5 — Why female literacy is important.
  • Better health outcomes for children of literate mothers.
  • Lower fertility (educated women have fewer children).
  • Higher household income.
  • More political participation.
  • Better life satisfaction.

✦ Answer: Female literacy lags male literacy by ~14 points due to historical deprivation, economic constraints favouring boys, patriarchal attitudes, and inadequate infrastructure. Government schemes (RTE, BBBP, scholarships) are slowly closing the gap. State variation is high — Kerala 92%, Bihar 53%.

Question 9

What are the challenges of India's urbanisation?

Accepted Answer

Step 1 — Scale of urbanisation.
  • 1901: ~11% urban.
  • 1951: ~17% urban.
  • 2011: ~31% urban.
  • 2024: ~36% urban.
  • 2050: projected 50%+ urban.
  India is urbanising rapidly. Adding ~10 million urban residents per year.

Step 2 — Top metropolitan areas.
  Delhi-NCR: 33 million.
  Mumbai: 22 million.
  Kolkata: 15 million.
  Bangalore: 14 million.
  Chennai: 12 million.
  Hyderabad: 10 million.

Step 3 — Major urban challenges.

(a) SLUMS AND HOUSING.
  • ~65 million Indians live in slums.
  • Housing shortages, high prices in major cities.
  • Informal settlements with poor infrastructure.

(b) WATER AND SANITATION.
  • Many cities face seasonal water shortages.
  • Inadequate sewage treatment.
  • Open defecation in some areas.

(c) TRANSPORTATION.
  • Traffic congestion.
  • Inadequate public transport (compared to demand).
  • Long commutes (60+ minutes one way in major cities).
  • Air pollution from vehicles.

(d) POLLUTION.
  • Air pollution (Delhi consistently among world's most polluted).
  • Water pollution (industrial + sewage).
  • Solid waste management (landfills overflowing).

(e) INEQUALITY.
  • Stark contrast between rich neighbourhoods and slums.
  • Limited access to good schools, healthcare for the poor.

(f) UNEMPLOYMENT.
  • Urban underemployment is a major issue.
  • Many migrants find informal, low-wage work.

(g) ENVIRONMENTAL DEGRADATION.
  • Loss of green space.
  • Urban heat island effects.
  • Reduction in groundwater levels.
  • Loss of natural drainage and flood control.

Step 4 — Government response.
  • Smart Cities Mission.
  • Swachh Bharat (Clean India) Mission.
  • AMRUT (Atal Mission for Rejuvenation and Urban Transformation).
  • Pradhan Mantri Awas Yojana (housing).
  • Urban transport investments.

✦ Answer: India's rapid urbanisation has created challenges in housing (65M in slums), water and sanitation, transportation, pollution, inequality, unemployment, and environmental degradation. Government missions (Smart Cities, Swachh Bharat, AMRUT) are addressing these — but the pace of urbanisation outstrips infrastructure development.

Question 10

Describe the demographic transition of India.

Accepted Answer

Step 1 — What is demographic transition?
  Demographic transition is the long-term pattern of population change as a country DEVELOPS economically. All countries go through four (or five) stages.

Step 2 — Stage 1: High Stationary (pre-1921 in India).
  • Birth rate: HIGH (~50 per 1,000).
  • Death rate: HIGH (~50 per 1,000) — due to disease, famine, war.
  • Population growth: VERY SLOW (~0.2% per year).
  • This is the 'pre-modern' state — characterised the world for most of human history.

Step 3 — Stage 2: Early Expanding (1921-1951 in India).
  • Birth rate: STILL HIGH (~45 per 1,000).
  • Death rate: BEGINS TO FALL (~35 by 1951).
  • Triggered by: improved medicine (vaccines), sanitation, transport (reducing famines), better food.
  • Result: RAPID POPULATION GROWTH (~1.2% per year).
  • This is the 'population explosion' phase.
  • India entered this phase later than Western countries (about 100 years late).

Step 4 — Stage 3: Late Expanding (1951-2001 in India).
  • Birth rate: STARTS FALLING (45 → 24 per 1,000).
  • Death rate: CONTINUES TO FALL (~10 per 1,000).
  • Triggered by: declining fertility due to family planning, female education, urbanisation, economic development.
  • Result: GROWTH SLOWING (~2.0% per year — still high but declining).
  • Cultural changes — preference for smaller families.

Step 5 — Stage 4: Low Stationary (2001 onwards in India).
  • Birth rate: LOW (~17 per 1,000 in 2024).
  • Death rate: LOW (~7 per 1,000).
  • Result: SLOW POPULATION GROWTH (~1.0% per year, falling).
  • TFR (Total Fertility Rate): 2.0 — BELOW REPLACEMENT level (2.1).
  • Population still grows because of demographic momentum (large existing reproductive-age cohorts).
  • India officially reached this stage around 2010-2015.

Step 6 — Stage 5: Declining (potentially after 2050 for India).
  • Birth rate: VERY LOW (already in countries like Japan, South Korea, China).
  • Death rate: stable or slightly rising due to ageing.
  • Population: DECLINES.
  • China is currently in this stage (already declining).
  • India: projected peak ~2065 at 1.65 billion, then decline.

Step 7 — Why demographic transition matters.
  Each stage requires different policy:
  • Stage 2: focus on reducing fertility, improving healthcare.
  • Stage 3: invest in education, jobs to absorb growing workforce.
  • Stage 4: maximise the demographic dividend (we are here NOW).
  • Stage 5: prepare for ageing — pensions, eldercare.

Step 8 — Comparison with other countries.
  • UK: completed transition by 1900.
  • China: completed transition by 2000.
  • India: completing transition now (2025).
  • Africa: many countries still in Stage 2-3.

Step 9 — Implications for India today.
  • Demographic dividend is available NOW.
  • Need to invest in education, jobs, healthcare to harness it.
  • Population will peak ~2065 then decline.
  • Ageing will be a challenge post-2050.
  • India's window of opportunity is the next 25-30 years.

✦ Answer: India's demographic transition unfolded over the 20th century:
• Stage 1 (pre-1921): high birth + high death rates, slow growth.
• Stage 2 (1921-1951): death rates fell with better medicine, birth rates stayed high — population exploded.
• Stage 3 (1951-2001): birth rates also began falling. Growth slowed.
• Stage 4 (2001-now): low birth + low death rates. Now below replacement TFR.
• Stage 5 (post-2050): population may decline.
India is currently in Stage 4 with demographic dividend opportunity until ~2050.

Question 11

What is the National Population Policy 2000 of India? What are its main objectives?

Accepted Answer

Step 1 — Background.
  Before 2000, India had various family planning programs but no comprehensive population policy. The 1976 emergency-era policy of forced sterilizations was a disaster — discrediting government population programs for decades.
  The 2000 policy was a new, voluntary, rights-based approach.

Step 2 — Date and adoption.
  • National Population Policy (NPP) adopted in February 2000.
  • Government of India under Atal Bihari Vajpayee.
  • Drafted by a National Commission on Population.

Step 3 — Vision.
  Population stabilisation, not control. A voluntary approach respecting individual rights.
  Linked to broader development goals — quality of life, education, health.

Step 4 — Immediate objectives.
  • Address unmet need for contraception.
  • Provide healthcare and infrastructure.
  • Improve mother and child health.
  • Provide family planning services to all who want them.

Step 5 — Medium-term objectives (by 2010).
  • Achieve replacement-level fertility (TFR = 2.1).
  • Provide complete coverage of vaccinations.
  • Universal primary education.
  • Reduce maternal mortality.

Step 6 — Long-term objectives (by 2045).
  • Stable population.
  • Improved overall quality of life.
  • Sustainable economic development.

Step 7 — Major program components.

(a) Health.
  • Janani Suraksha Yojana — financial assistance for safe maternity.
  • Pradhan Mantri Matru Vandana Yojana — cash transfer for pregnant women.
  • Mission Indradhanush — vaccination drive.
  • Ayushman Bharat — health insurance.

(b) Education.
  • Right to Education Act (2009).
  • Mid-day meals.
  • Free books and uniforms.

(c) Family planning.
  • Free contraceptives.
  • Counseling.
  • Voluntary sterilisation.
  • Promotion of two-child families.

(d) Empowerment.
  • Beti Bachao Beti Padhao (girl child welfare).
  • Skill development programs.
  • Increased female education focus.

Step 8 — Results.
  • TFR achieved replacement level (~2.0 in 2021) — major success.
  • Maternal mortality reduced from 330/100,000 (2000) to ~ 100/100,000 (2024).
  • Infant mortality reduced from 70/1000 to ~ 30/1000.
  • Female literacy increased.
  • Sex ratio improving.

Step 9 — Continuing challenges.
  • Population still growing due to demographic momentum.
  • Regional disparities (Bihar, UP have higher fertility than Kerala, TN).
  • Need for continued investment in education, healthcare.
  • Quality of services varies by state.

Step 10 — Future directions.
  • Continue focusing on female education.
  • Address gender-based sex selection.
  • Plan for ageing post-2050.
  • Sustainable development goals.

✦ Answer: National Population Policy 2000 is India's voluntary, rights-based approach to population stabilisation. Adopted Feb 2000. Aims to achieve replacement-level TFR (2.1) by 2010 (achieved 2021), stable population by 2045. Focuses on health, education, family planning, and women's empowerment. Major schemes: Janani Suraksha Yojana, RTE, Beti Bachao Beti Padhao, Ayushman Bharat. Results: TFR below replacement, maternal mortality halved, literacy up. Continuing challenges: regional disparities, ageing planning.
