India’s Next Census Scheduled for 2027

  • The government has announced that the next nationwide population census will begin on April 1, 2026.
  • Key Features of the 2027 Census
    • First Digital Census: The upcoming exercise will be India’s first fully digital census.
    • Caste Enumeration: For the first time since Independence, the census will include caste-based data collection.
  • Timeline and Phases
    • The census will be held in two phases:
      • House Listing and Housing Schedule
      • Population Enumeration (includes caste data)
    • Both phases will span April 1, 2026 to February 28, 2027.
  • Reference Date:
    • March 1, 2027 (for most of India)
    • October 1, 2026 (for Ladakh and snow-bound areas in J&K, Himachal Pradesh, and Uttarakhand)
  • Legal and Procedural Aspects
    • The census will be conducted under the Census Act, 1948 and the Census Rules, 1990.
    • A gazette notification under Section 3 of the Census Act is expected soon, which will formally announce the schedule.
  • Political Implications
    • As per the constitutional mandate, the first census after 2026 can be used for the delimitation of Lok Sabha constituencies.
    • This data could form the basis for electoral constituency restructuring before the 2029 General Elections.
  • Impact on Women's Reservation
    • The 33% reservation for women in the Lok Sabha and State Assemblies, as mandated by the recently passed Women’s Reservation Act, will also come into force only after a new delimitation exercise is conducted based on post-2026 census data.
  • No Update on NPR
    • There was no mention of updating the National Population Register (NPR) during the announcement.
      • As per Citizenship Rules, 2003, NPR is the first step toward compiling a National Register of Indian Citizens (NRIC/NRC).
  • Background
    • The last census was conducted in 2011, with the first phase held in 2010.
    • The 2021 census was delayed due to the COVID-19 pandemic and other administrative reasons.

Delimitation to Begin After Release of Census 2027 Data

  • Once the final census data is released in late 2027, the process of delimitation will begin.
  • The Parliament must first pass a new Delimitation Act to legally empower the formation of a Delimitation Commission.
  • Legal Provision and mandate
    • The process is mandated under Articles 81 and 82 of the Constitution, which require delimitation after every Census.
    • Once formed, the Commission will consult state governments and stakeholders to devise a formula based on population per constituency.
  • Formation and Composition of the Delimitation Commission
    • The Delimitation Commission will be:
      • Headed by a retired Supreme Court judge
      • Include the Chief Election Commissioner and State Election Commissioners
      • Assisted by MPs and MLAs from states as associate members (without voting rights)
  • Historical Background
    • Delimitation was done after the 1951, 1961, and 1971 censuses.
    • The 42nd Constitutional Amendment (1976) froze the number of seats until after the 2001 Census.
    • The 84th Constitutional Amendment (2002) extended this freeze until the first census after 2026.
  • Current Scenario
    • The current 543 Lok Sabha seats are based on the 1971 Census.
    • The Delimitation Act of 2002 allowed only boundary redrawing, not an increase in seat numbers.
    • To increase seats, a Constitutional Amendment is required, needing a two-thirds majority in Parliament.
  • Political and Regional Challenges
    • Southern states may lose out in a population-based seat redistribution, as they have successfully controlled population growth.
    • Maintaining the current cap of 550 seats (Article 81) without increasing total seats could disadvantage them further.
