North-South Demographic Divide
India's population growth has been highly uneven across regions. Southern states (Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Telangana) achieved replacement-level fertility (Total Fertility Rate ≈ 1.7–2.0) by the 1990s–2000s, while several northern states (UP, Bihar, Rajasthan, MP) still have TFRs above the national average of 2.0. Since Lok Sabha seats are allocated proportionally to population (Article 81), states that reduced fertility face a structural paradox: good governance on population policy reduces political representation.
- Tamil Nadu and Kerala together have about 50 Lok Sabha seats currently; under fresh delimitation based on 2027 population data, their share could fall relative to UP and Bihar.
- The 1971 census freeze (84th Amendment) was explicitly designed to protect southern states from this penalty during the Emergency era.
- The proposed 816-seat expansion aims to mitigate this by enlarging the total pie — all states gain seats in absolute terms, even if relative shares shift.
- At 816 seats with 33% women's reservation, total women's seats would be 273 (up from current 82 women MPs, about 15%).
