What Happened
- The first phase of Census 2027 — House Listing and Housing Operations — formally begins on April 1, 2026, making it the first phase of India's 16th national census.
- Self-enumeration (where households upload their own data) begins on April 1 for eight states and UTs including Delhi, Goa, Karnataka, Odisha, Sikkim, Mizoram, Andaman and Nicobar Islands, and Lakshadweep.
- The government has notified 33 questions for Phase 1 covering housing conditions, amenities, asset ownership, and household composition.
- Caste enumeration will be conducted in Phase 2 (Population Enumeration phase, beginning February 2027), not Phase 1 — the specific caste questions will be notified separately before Phase 2 begins.
- This will be India's first full digital census, with self-enumeration available via the portal se.census.gov.in; a 16-digit unique Self-Enumeration ID is generated for each household.
- Data provided will be legally protected as confidential under the Census Act, 1948.

The Census in India — Constitutional and Legal Basis
The Census of India is conducted under the Census Act, 1948, which mandates decennial population counts and empowers the Registrar General of India (RGI) to collect demographic data. Article 246 of the Constitution places "census" in the Union List (Entry 69, Seventh Schedule), making it an exclusive central subject. The census forms the statistical backbone for delimitation of constituencies, allocation of central funds (Finance Commission devolution), reservation rosters, and development planning. The last census was conducted in 2011; the 2021 census was postponed due to the COVID-19 pandemic, making 2027 census a long-delayed exercise.
- Census 2027 is India's 16th national census; the previous one in 2011 counted 1.21 billion people.
- The Census Act, 1948 (Section 15) makes it mandatory to answer census questions; false answers attract penalties.
- The RGI and Census Commissioner of India is the nodal authority.
- Self-enumeration portal: se.census.gov.in; households generate a 16-digit ID for enumerator verification.
- Phase 1 (House Listing): April 1 – September 30, 2026, across all states/UTs in staggered windows of 30 days each.
Connection to this news: The commencement of Phase 1 on April 1, 2026 marks the formal restart of India's census machinery after a five-year gap, with digital self-enumeration as its most significant process innovation.
Caste Enumeration — Historical and Political Context
India last conducted a full caste census in 1931 under British rule. Post-Independence censuses have enumerated Scheduled Castes and Scheduled Tribes but not OBC (Other Backward Classes) sub-groups. The Mandal Commission (1980) estimated OBC population at 52% based on 1931 data — a figure still contested. The Socio-Economic and Caste Census (SECC) 2011 collected caste data but was never officially published in full. The inclusion of caste enumeration in Census 2027 follows significant political pressure from OBC-dominant states and multiple Supreme Court cases on sub-classification within reservations.
- Caste questions will be part of Phase 2 (Population Enumeration, February 2027), not the ongoing Phase 1.
- Specific questions on caste have not yet been finalised; they will be notified after consultations with ministries, departments, and census data users.
- The Supreme Court's August 2024 judgment in Punjab v. Davinder Singh permitted sub-classification within SC/ST reservations, making precise caste data more legally significant.
- Bihar was the first state to conduct its own caste survey (2023), estimating OBC + EBC population at ~63% of the state.
Connection to this news: The placement of caste enumeration in Phase 2 — with questions still to be notified — reflects the political sensitivity of the exercise, even as the government has committed to including it for the first time since Independence.
Digital Census and Self-Enumeration
Census 2027 introduces self-enumeration, allowing households to register directly on a government portal before enumerators arrive. This reduces enumerator bias, speeds up data collection, and creates a verifiable digital trail. Self-enumeration operates as a 15-day window that precedes the 30-day house-to-house houselisting operations in each state/UT. The 16-digit Self-Enumeration ID generated by the portal must be shared with the visiting enumerator for cross-verification — making it a hybrid digital-field process rather than a fully online census.
- Portal: se.census.gov.in — households register using mobile number and basic details, pin house location on a map.
- 33 questions in Phase 1 cover: building materials (floor, wall, roof), drinking water source and availability, lighting source, latrine type, drainage, kitchen and bathing facilities, asset ownership (TV, internet, smartphone, bicycle, car).
- Live-in couples will be counted under the same household for the first time.
- Data is protected under the Census Act, 1948; individual-level data cannot be shared with any other government department.
Connection to this news: The digital-first approach and self-enumeration option address longstanding concerns about enumerator quality and data accuracy, while also broadening access for literate, urban households.
