What Happened

Approximately 82 lakh (8.2 million) households have opted for the self-enumeration facility during the initial phase of Census 2027's Houselisting and Housing Operations (HLO).
Enumerators commenced ground-level field operations on 1 May 2026 in six states and union territories: Andhra Pradesh, Arunachal Pradesh, Haryana, Madhya Pradesh, Chhattisgarh, and Chandigarh UT.
The HLO exercise in these regions will continue through 30 May 2026; different states follow staggered schedules with the overall HLO phase running April–September 2026.
Self-enumeration, available for a 15-day window before house-to-house visits, lets households log onto a secure portal using a mobile number, fill in details, generate a unique ID, and hand it to enumerators during verification visits.
Enumerators use a dedicated mobile application for data collection — making Census 2027 India's first fully digital census.
Each household faces 33 questions covering home facilities, household composition, member names and gender, and property ownership.
The Cabinet Committee on Political Affairs (CCPA) decided on 30 April 2025 that Census 2027 will also conduct caste enumeration during Phase II (Population Enumeration, February 2027).

Static Topic Bridges

Census Act, 1948 and the Legal Framework

The Census of India is governed by the Census Act, 1948 (Act No. 37 of 1948, as amended in 1994). Participation in the census is mandatory under this Act. The Census Commissioner is appointed under Section 4(1) of the Census Act by the Central Government. The office is officially designated as the Registrar General and Census Commissioner of India, functioning under the Ministry of Home Affairs.

Census Act, 1948 — primary enabling legislation; makes census participation compulsory
The Registrar General is responsible for planning, coordination, supervision of field activities, data processing, tabulation, and dissemination of census results
Census falls under Entry 69 of the Union List (Seventh Schedule) — exclusively a Central Government function
Post-1949, all censuses have been conducted by the Registrar General under the Ministry of Home Affairs
India has conducted censuses decennially since 1881 (during British rule) and continuously since independence — the 2021 Census was postponed due to COVID-19, making 2027 the first census since 2011

Connection to this news: The Census Commissioner, operating under the Census Act, 1948, is responsible for rolling out the 2027 Census including the digital innovations such as the self-enumeration portal and mobile-based field enumeration.

HLO Phase vs Population Enumeration Phase: Two-Phase Structure

Census 2027 follows a two-phase structure, a practice that has evolved since the 1990s to improve data quality.

Phase I — Houselisting and Housing Operations (HLO): Scheduled April–September 2026 (30-day window per state). Focuses on housing units, household facilities, and structural data. Self-enumeration option available for 15 days before house-to-house visits. Enumerators ask 33 questions.
Phase II — Population Enumeration (PE): Scheduled February 2027. Captures detailed demographic, socio-cultural, economic, migration, and fertility data of individuals. Caste enumeration to be conducted in this phase.
Near Real-Time Monitoring: Census Management & Monitoring System (CMMS) portal enables supervisors to track field progress digitally.
The two phases are separated by a gap of six to eight months.

Connection to this news: The current news marks the start of Phase I field operations. The 82 lakh self-enumeration households represent an early indicator of public adoption of the digital-first approach that is new to Census 2027.

Census Data and Constitutional/Policy Significance

Census data is the bedrock of India's constitutional, representational, and welfare architecture. Its delayed completion since 2011 has had wide cascading effects.

Delimitation of parliamentary and assembly constituencies under Article 82 (Lok Sabha) and Article 170 (State Assemblies) is based on Census data — the pending delimitation (and consequently the 106th Amendment's women's reservation) are blocked until Census 2027 data is available
Article 330 (reservation for SC/ST in Lok Sabha) and Article 332 (in State Assemblies) require updated Census-based population ratios for recalculation
Welfare scheme targeting, MGNREGS allocations, hospital and school planning, and financial devolution formulas (Finance Commission) all depend on Census data
The 2011 Census recorded India's population at 121.1 crore; Census 2027 is expected to enumerate approximately 145–150 crore people
India has missed the global standard of decennial census — the 16-year gap (2011–2027) is the longest in independent India's history

Connection to this news: The commencement of field operations is the most visible step toward resolving the data vacuum that has constrained constitutional processes (delimitation, reservation recalculation) and welfare targeting since 2021.
