Census 2027 – Overview
The Census 2027 is a landmark exercise. It will be the first digital census in independent India and the first to enumerate caste beyond Scheduled Castes (SC) and Scheduled Tribes (ST). The Cabinet Committee approved this expansion in April 2025, signalling a major policy shift.
Key Developments
- Phase‑1 – Housing Listing Operations (HLO) began on 1 April 2026 and will end on 30 September 2026 across all States and Union Territories.
- Phase‑2 – Population Enumeration (PE) is scheduled for February 2027, with a rehearsal held from 1‑20 July 2026 in 16 regions.
- Caste data for all communities will be captured during PE, using an open‑column format for non‑SC/ST groups.
- Self‑enumeration will be available from 17‑31 August 2026, allowing citizens to submit details online in 16 languages.
- Around 30 lakh field functionaries, including enumerators and supervisors, will be deployed.
Important Facts
The first phase (HLO) includes 33 questions covering household head gender, cereal consumption, and number of couples. The second phase (PE) will ask 40 questions, adding items on COVID‑19 vaccination, bank accounts, and various identity proofs.
Key additions are:
- Explicit caste enumeration for every resident.
- Digital literacy status, mobile number, Aadhaar, Voter ID, passport, and driving licence details.
- COVID‑19 vaccination place, reflecting health‑policy integration.
Exam Relevance
Understanding the census is crucial for GS‑1 (Demography) and GS‑3 (Economy). The expanded caste data will aid policymakers in assessing social equity, reservation policies, and targeted welfare schemes. The digital mode showcases India’s push towards e‑governance, relevant for questions on technology adoption in administration.
The role of the RG&CCI highlights institutional responsibilities and inter‑ministerial coordination, a common UPSC theme.
Way Forward
Students should monitor the rollout of self‑enumeration platforms, as they illustrate citizen‑centric data collection. Analysts must watch how the caste data influence future policy debates on affirmative action and social justice. Finally, the success of the digital infrastructure will set a precedent for other large‑scale government surveys.
