Constitutional Provisions Related to Delimitation

History of Delimitation Exercises in India
Delimitation has been undertaken four times:
- 1952
- 1962
- 1972
- 2002
The Post-1972 Concern
After the delimitation of 1972, it was the thought that any further delimitation would alter share of states in lok sabba detrimentally affecting the southern States which were successful in implementing population control programmes as these seats could be appropriated by the states which witnessed exponential population growth.
Constitutional Amendments and Freeze on Delimitation
- 42nd Constitutional Amendment Act, 1976 stalled any further delimitation till the year 2000, and share of States in Lok Sabha was frozen till 2026.
- Once the probibition period got over in 2000, Parliament passed 84th CAA 2001 to provide for fresh delimitation on the basis of 1991 census figures.
- Delimitation Act, 2002: Parliament passed the Delimitation Act -constituted a three-member Delimitation Commission;Empowered it to redraw constituency boundaries.
- 87th Constitutional Amendment Act, 2003: Allowed use of 2001 Census data instead of 1991 Census.
The Post-2026 Scenario: What Lies Ahead?

- As per the 84th Constitutional Amendment: Fresh delimitation is not mandatory until the first Census after 2026.
