BharatNotes What is Demographic Ageing?
Demographic ageing is the structural increase in the proportion of older persons in a population, paired with a rise in the median age. In India, "elderly" conventionally means persons aged 60 years and above. The phenomenon is the by-product of the demographic transition: as a society industrialises, death rates fall first (raising life expectancy) and birth rates fall later. Once fertility drops below the replacement level (a Total Fertility Rate of about 2.1), the base of the population pyramid narrows while its apex widens — and the share of the elderly steadily climbs.
Key Drivers
- Falling fertility — India's TFR is now around 2.0, below the replacement level of 2.1 (NFHS-5, 2019-21).
- Rising life expectancy — life expectancy at birth has risen to roughly 70 years, improving survival into old age.
- Past high-fertility cohorts — large generations born in earlier decades are now entering old age, accelerating the shift.
Current Status (date-stamped)
| Indicator | Value | Source / Year |
|---|---|---|
| Elderly (60+) share | ~10.1% (138 million) | NSO, Elderly in India 2021 |
| Projected 60+ share, 2050 | ~20.8% (347 million) | UNFPA India Ageing Report 2023 |
| Growth of 80+ population, 2022-2050 | ~279% | UNFPA India Ageing Report 2023 |
| Old-age dependency ratio | 15.7% (2021) → 20.1% (2031) | NSO, Elderly in India 2021 |
| Elderly sex ratio | 1,065 women per 1,000 men | NSO, Elderly in India 2021 |
| State with highest elderly share | Kerala, ~16.5% | NSO, Elderly in India 2021 (2021) |
By around 2046, the elderly are projected to outnumber children aged 0-14 (UNFPA, 2023). The higher elderly sex ratio reflects the feminisation of ageing — older women outlive men but are more likely to be widowed, without independent income, and dependent on family.
Significance and Challenges
Ageing carries fiscal and social weight: a rising old-age dependency ratio strains pensions and the working-age tax base; chronic and geriatric illness raises health-care costs; and the decline of joint families leaves many elderly socially and financially vulnerable. India also faces a uneven transition — southern states (Kerala, Tamil Nadu) are ageing far ahead of younger northern states, complicating uniform policy.
Policy Response
- Maintenance and Welfare of Parents and Senior Citizens Act, 2007 — makes maintenance of parents/senior citizens a legal obligation, with tribunals for enforcement.
- National Programme for Health Care of the Elderly (NPHCE) — geriatric care across primary, secondary and tertiary levels (Ministry of Health & Family Welfare).
- Indira Gandhi National Old Age Pension Scheme (IGNOAPS) — monthly pension for below-poverty-line elderly.
UPSC Angle
Treat demographic ageing as the flip side of the demographic dividend: India must convert its current youth bulge into productivity before the ageing burden peaks. Strong answers link the data (60+ share, dependency ratio, feminisation) to policy gaps in pensions, geriatric health, and elderly-care infrastructure — a foundation concept that recurs across population, society and welfare-policy questions.
