India's Fertility Falls Below Replacement: SRS 2024 and NFHS-6 Confirm Demographic Shift

Political & Constitutional

• The north-south fertility divergence collides with the looming delimitation of Lok Sabha seats. Southern states that controlled population early (TFR ~1.3-1.5) fear losing parliamentary weight to high-fertility northern states (Bihar 2.9, UP, MP), raising federalism and representation tensions.
• Fertility, public health and family welfare sit on the Concurrent List, requiring Centre-State coordination.

Economic & Financial

• A 66.4% working-age share is India's window to grow rich before it grows old — but only if jobs, skills and female labour-force participation rise. The dividend is expected to peak around 2036-2041; the risk is India "ageing before becoming rich."
• A shrinking future workforce and rising old-age dependency will strain pensions, healthcare and elder-care financing.

Social Dimensions

• Falling fertility reflects female empowerment — later marriage, education, contraception — a development success, not merely a policy target.
• Persisting IMR gaps (Kerala 8 vs Chhattisgarh 36) expose unequal health outcomes; SRB at 918 signals lingering son-preference and sex-selection concerns.

Governance & Administrative

• The jump in institutional deliveries (90.6%) and insurance coverage (60.2%) validates NHM, JSY/JSSK and Ayushman Bharat.
• Even where institutional delivery is near-universal (e.g. Chhattisgarh), high IMR shows last-mile and post-natal health delivery remains weak.

International Perspective

• India mirrors the path of China, Japan and South Korea, but at a lower per-capita income — heightening the ageing-before-rich risk.
• It aligns with SDG-3 (health) and SDG-5 (gender equality) and reframes the global narrative from "population explosion" to managing transition and ageing.
