Census and Delimitation
The Political Dimension
Delimitation refers to the process of redrawing boundaries of electoral constituencies based on the latest census data. The Constitution (84th Amendment) Act, 2002 froze the total number of Lok Sabha and State Assembly seats based on the 1971 Census until the first census after 2026. With Census 2027 data, the long-deferred delimitation exercise can proceed, potentially reshaping India's political map.
- Article 82 — Readjustment of Lok Sabha seats after each census (currently frozen based on 1971 data by 84th Amendment, 2002)
- Article 170 — Readjustment of State Assembly seats after each census (similarly frozen)
- 84th Amendment (2002): Extended the freeze on delimitation (originally from 42nd Amendment, 1976) until the first census after 2026
- The Delimitation Commission is constituted under the Delimitation Act; most recent was the Delimitation Commission of 2020 (for J&K only, under the J&K Reorganisation Act, 2019)
- Political concern: Southern states (Tamil Nadu, Kerala, Andhra Pradesh, Karnataka, Telangana) which achieved lower population growth through successful family planning programmes fear losing relative representation if seat allocation is purely population-based
- 15th Finance Commission introduced a compromise: Used 2011 population for tax devolution (not 1971), while political representation (seats) remained frozen
