Demographic and Social Factors in India’s Population Growth — 2025 Paper II

Question · 2025 · Paper II · 15 Marks

Elucidate the role of demographic and social factors for population growth in India.

Model Answer

VAID ICS

Introduction

Population growth is determined demographically by births minus deaths plus net international migration. In India, the twentieth-century acceleration resulted mainly from a rapid decline in mortality while fertility remained high. Fertility has now fallen to about replacement level nationally, but population continues to increase because of population momentum and large regional differences.

Demographic factors

  • Fertility: The number and timing of births directly determine natural increase. NFHS-5 reported an all-India total fertility rate of about 0, but rates remain higher in some states and social groups.
  • Mortality decline: Vaccination, antibiotics, sanitation, maternal-child health and food security reduced death and infant mortality. Initially, more surviving children enlarged the population before desired family size adjusted.
  • Age structure and momentum: A large cohort entering reproductive ages produces many births even when each woman has fewer children. This is now a central reason for continued growth.
  • Nuptiality: Early and near-universal marriage lengthens exposure to childbearing; delayed marriage and first birth reduce completed fertility.
  • Life expectancy and ageing: Longer survival increases population stock and gradually raises the elderly share, even as growth slows.
  • Migration: Internal migration redistributes people towards cities and growth centres but does not add to India’s total population; net international migration has a comparatively small role.

Social factors shaping fertility and mortality

  • Female education and autonomy: Schooling delays marriage, increases paid work and contraceptive knowledge, and lowers desired family size.
  • Child survival: Where infant mortality is high, families may have additional births as insurance. Reliable child health services accelerate fertility decline.
  • Son preference: Sex-selective stopping behaviour and the desire for at least one son can increase parity and distort the sex ratio.
  • Poverty and agrarian livelihood: Children may contribute labour and old-age security, while pensions and secure employment reduce this economic motive.
  • Urbanisation: Housing costs, education expenses, women’s employment and reduced value of child labour favour smaller families.
  • Access to contraception and healthcare: Quality, informed choice and spacing methods matter more than target-driven or coercive programmes.
  • Culture and social norms: Family expectations, kinship and religion influence behaviour, but their effects are substantially mediated by education, residence, class and gender relations.

Critical perspective

India is in different stages of demographic transition simultaneously. Southern and several western States face low fertility and ageing, while parts of the north-central belt retain youthful age structures. The Economic Survey 2018-19 projected India’s working-age share to peak around 2041; it did not say that the demographic-dividend opportunity would abruptly close in that year. Converting the window into gains requires health, education, skilling, employability and higher female labour-force participation. Policy must move beyond the language of a uniform “population explosion” towards reproductive rights and region-specific planning.

Conclusion

India’s population trajectory reflects mortality transition, fertility decline and age-structural momentum, all shaped by education, gender, livelihood and public policy. Social development - especially women’s agency and child survival - is the most durable and ethical route to population stabilisation.

Diagram to draw: High mortality/high fertility -> mortality decline -> rapid growth -> fertility decline -> momentum -> stabilisation and ageing; add “working-age share peaks around 2041” as a value-add.
