Population Policy - Demographic Dividend & Census 2027

The Big Shift — India's Fertility Rate Has Fallen Below Replacement

• India's Total Fertility Rate (TFR) has fallen to 1.9 children per woman (UNFPA State of World Population 2025) — below the replacement level of 2.1 needed to sustain population size across generations without migration.
• NFHS-6 (fact sheet released May 2026, covering survey year 2023-24) confirms the national TFR at approximately 2.0, essentially unchanged from NFHS-5 (2019-21) — the fastest and steepest fertility decline of any large country in recent decades, down from 3.39 in 1990-92.
• Popular misconception: this does not mean India's population is shrinking today — due to demographic momentum (a large existing cohort of young people still entering reproductive age), India's population will keep growing for decades, projected to peak around 1.7 billion roughly 40 years from now before beginning to decline.

The Regional Fertility Divide — Not a Uniform National Story

📊 India's regional fertility divide, NFHS-6 (2023-24)

• Southern/Western states — Tamil Nadu (1.7), Kerala (1.8), Andhra Pradesh (1.8), Karnataka (1.8), Telangana (1.9) — reached replacement fertility decades ago (Kerala in 1988, Tamil Nadu in 1993, Andhra Pradesh in 2004) and are now well into population ageing, not growth.
• Northern/Central states lag far behind: Bihar (2.7, down from 3.0 in NFHS-5), Uttar Pradesh and Jharkhand (2.2), with Bihar not expected to reach replacement fertility until 2039 — the last major state to do so.
• Rajasthan and Madhya Pradesh sit right at replacement level (2.1) but notably showed a slight increase from NFHS-5 — a rare and closely watched reversal against the broader national declining trend.

The Demographic Dividend — A Closing Window

• India's working-age population (15-59) is projected to peak in 2041 at approximately 1.01 billion, before beginning to decline — meaning India has a limited, closing window to convert its favourable age structure into economic growth.
• Analysts increasingly frame this as requiring a shift from a passive 'demographic dividend' (simply having a large working-age population) to an active 'productivity dividend' — sustained investment in education quality (Part 7), healthcare access, and formal job creation to ensure that large cohort is actually productively employed, not merely numerically present.
• Risk framing: commentators warn India could "age before it gets rich" — i.e., see its working-age share shrink before per-capita income and institutional capacity reach levels achieved by countries (Japan, South Korea) that industrialized before their demographic transition matured.

Population Projections and Census 2027's Role

Projection Detail

Current population (2026) Approximately 1.476 billion (17.79% of world population) — world's most populous nation

Projected peak 1,590.1 million by 2051 (Population Foundation of India / IIMAD projections); annual growth rate slowing to 0.5%

Population stabilization target Originally targeted for 2045; now pushed back to approximately 2065 given slower-than-expected decline in some states

Regional population-share shift Northern/Central India's population share projected to rise to 52.7% by 2051; Southern share to fall to 17%

School enrolment impact (already National school enrolment (pre-primary to Class 12) fell by 13.4 million between 2019 visible) and 2025, partly reflecting the fertility decline already working through the system
