Q. The population figures of which among the following censuses is basis of delimitation currently?
Answer: 2001 Census
Notes: Delimitation is the process of redrawing the boundaries of parliamentary and assembly constituencies. The current delimitation of parliamentary constituencies in India is based on the 2001 census. The 2001 census figures were used under the Delimitation Act of 2002. The first election to use the new boundaries was in Karnataka in May 2008.  The total number of seats in the Lok Sabha and the number of seats allotted to each state remained unchanged. The distribution of seats in the Parliament is based on the 1971 census. The freeze on the number of seats in the Lok Sabha and Assemblies was extended until 2026. The delimitation will take place after the first decennial census after 2026.
