The Government of India has constituted four Delimitation Commissions up until December 2023. These commissions were established to carry out the task of redrawing the boundaries of various electoral constituencies in India. The primary objective of delimitation is to ensure that each constituency has roughly the same population, thereby maintaining the principle of "one person, one vote."
1. Delimitation Commission of 1952: The first Delimitation Commission was set up after the first general elections in independent India. The main task was to readjust the boundaries of the constituencies based on the 1951 Census, ensuring fair representation as India embarked on its democratic journey.
2. Delimitation Commission of 1963: The second Delimitation Commission was constituted following the 1961 Census. Its objective was to reassess and realign the boundaries of constituencies based on the changes in population that occurred over the decade.
3. Delimitation Commission of 1973: Established after the 1971 Census, this commission had the task of further adjusting constituency boundaries to account for population changes over the previous decade.
4. Delimitation Commission of 2002: The fourth Delimitation Commission was set up after the 2001 Census. However, its work was carried out under unique circumstances because the Constitution of India was amended in 1976 (during the Emergency) to freeze the number of seats in the Lok Sabha and State Legislative Assemblies until 2000, based on the 1971 Census figures. The 84th Amendment extended this freeze until 2026.
