What This Article Covers

1.The delimitation of Lok Sabha seats remains frozen based on the 1971 Census due to the 42nd (1976) and 84th (2002) Amendments, creating a massive disparity in the value of a vote across states.

2.This malapportionment means an MP in Kerala represents 1.75 million citizens while an MP in Bihar represents 3.1 million, giving a Kerala vote almost twice the electoral weight.

3.Any future delimitation based on current population (post-2026) will require a fundamental reimagining of India's fiscal federalism, including greater financial devolution to states and a restructured Rajya Sabha.

The Big Picture
Prelims · HighMains · High

India's delimitation freeze, which uses 1971 population data to allocate Lok Sabha seats, violates the constitutional principle of 'one person, one vote' by creating severe malapportionment. Southern states with lower fertility face potential seat loss, raising critical questions about fiscal federalism and political representation that are central to UPSC Polity and Governance syllabus.
