What Happened

Field operations for Phase 1 of Census 2027 — the Houselisting and Housing Census (HLO) — commenced on May 1, 2026, in six states and one Union Territory: Andhra Pradesh, Arunachal Pradesh, Haryana, Chandigarh, Madhya Pradesh, and Chhattisgarh.
The launch follows the completion of a mandatory 15-day self-enumeration window (April 16–30, 2026) in these states, during which households could submit housing data online without a field visit.
Trained enumerators are now undertaking house-to-house visits across these states; field operations will continue through May 30, 2026.
As of the launch date, approximately 82 lakh households had opted for self-enumeration nationally, reducing the in-person enumeration workload.
The houselisting phase collects data on housing conditions, household amenities, and assets — forming the structural baseline before population enumeration in Phase 2.

Houselisting and Housing Census: Purpose and Scope

The Houselisting and Housing Census (HLO) is Phase 1 of the two-phase census process. It is not a population count — it maps the physical and material conditions of residential and non-residential buildings across India. This data feeds directly into housing policy, urban planning, infrastructure allocation (water, sanitation, electricity), and the National Buildings Register. The data distinguishes between census houses used for residential, religious, educational, commercial, and other purposes.

Data collected: building condition, roof/wall/floor materials, household amenities (water, electricity, sanitation), household assets.
Not a headcount — population enumeration happens in Phase 2 (February 2027).
Legal basis: Census Act, 1948; Census is a Union subject under Entry 69 of the Union List (Article 246).
Phase 1 creates a National Buildings Register that is used to assign unique building codes to each census house.

Connection to this news: The six states commencing HLO on May 1 are among the first batch in a staggered national rollout; the staggered approach allows central monitoring and quality control across India's diverse geographies.

Self-Enumeration as a Governance Innovation

The 15-day self-enumeration window ahead of field operations is a first in India's census history. Citizens access the census portal using their mobile number, fill in the housing schedule online, and generate a self-enumeration code that enumerators verify during field visits. This reduces doorstep friction, improves data completeness, and aligns with the Digital India programme's goal of reducing government-to-citizen contact points.

Self-enumeration period for this batch: April 16–30, 2026.
Platform: census self-enumeration portal (government-hosted).
82 lakh households nationally opted in during the self-enumeration phase.
Self-enumeration is optional — households that do not self-enumerate are visited by enumerators.

Connection to this news: The 82 lakh self-enumeration registrations across India represent a significant uptake, validating the digital-first design of Census 2027 and setting a precedent for future data collection exercises.

Staggered Census Rollout and Federal Implementation

Census 2027 is being conducted in staggered batches across states — not simultaneously. This staggering reflects the logistical scale of India's census (over 1.4 billion people, ~300 million households) and allows the Office of the Registrar General of India (ORGI) to provide state-specific training, troubleshoot mobile-app issues, and maintain quality. Different states have different houselisting schedules depending on local administrative calendars, seasonal considerations, and state government readiness.

Registrar General and Census Commissioner of India: nodal authority.
First six states/UT (May 1 batch): Andhra Pradesh, Arunachal Pradesh, Haryana, Chandigarh, Madhya Pradesh, Chhattisgarh.
Subsequent batches include other states (e.g., Goa, Karnataka, Odisha, Andaman & Nicobar Islands in later waves).
Field operations in each batch run for approximately 30 days.

Connection to this news: The concurrent commencement across six geographically and demographically diverse states tests the scalability of the digital census infrastructure before larger states (Maharashtra, West Bengal, Tamil Nadu) begin their operations.
