Delimitation Freeze

42nd Constitutional Amendment Act, 1976

• Froze the allocation of Lok Sabha and State Assembly seats among States based on the 1971 Census until after the 2001 Census.
• This was done to ensure that States successfully implementing Family Planning were not disadvantaged.

84th Constitutional Amendment Act, 2001

• Extended the freeze on the allocation of seats among States until the first Census after 2026.
• However, it allowed readjustment of constituency boundaries and SC/ST reserved seats based on the 2001 Census, without changing the total number of seats.

87th Constitutional Amendment Act, 2003

• Permitted delimitation using the 2001 Census instead of the 1991 Census, while continuing the freeze on the total number of seats.

Present Position (Updated)

• The 2002 Delimitation Commission implemented delimitation using the 2001 Census.
• Its recommendations came into effect in 2008.
• No nationwide delimitation has been carried out after 2008.
• The next nationwide delimitation exercise is expected after the publication of the first Census conducted after 2026, as required by the Constitution.

Exam Note: Although the constitutional freeze ends after the first Census conducted post-2026, the actual delimitation exercise will take place only after that Census is completed and Parliament enacts the necessary law.
