Census 2027, which commenced in April 2026, is the 16th census of India and the 8th since independence, the first fully digital census, and the first since independence to enumerate the caste of all communities. It arrives after the longest gap in census history (the 2021 round was postponed by COVID-19).
The Two Phases
| Phase | What | When |
|---|---|---|
| Phase 1: Houselisting and Housing Census (HLO) | 34 notified questions on housing stock and amenities | April-September 2026 (30 days per state/UT, with a 15-day self-enumeration window first) |
| Phase 2: Population Enumeration | Full demographic count including caste | February 2027 (September 2026 in snow-bound Ladakh, J&K, Uttarakhand, Himachal) |
The Digital Machinery
- 3.1 million+ field workers trained, working on a Bring-Your-Own-Device model
- HLO mobile app (Android/iOS) in 16 languages; CMMS management portal; HLBC satellite-imagery web app
- Self-enumeration portal: se.census.gov.in (an SE ID issues on completion); helpline 1855
- Legal basis: Census Act 1948 and Census Rules 1990; MHA notification June 16, 2025
- Chain of command: Union Home Ministry to the Registrar General and Census Commissioner of India to state Census Directorates
The 2011 Baseline It Updates
Population 121.0 crore; 25.0 crore households; literacy 73.0 percent; sex ratio 943; urban share 31.1 percent. Every welfare denominator, delimitation debate and reservation formula in use today still leans on these 15-year-old numbers.
Mains Angle
Why this census is consequential: caste enumeration will reset the empirical basis of reservation and welfare targeting; fresh population data feeds the frozen-since-1971 delimitation question and the women’s reservation timeline. Risks: digital exclusion in self-enumeration, data privacy in a BYOD exercise, and the political economy of caste data release. Way forward: publish anonymised microdata fast, and legislate clear rules on caste-data custodianship before release.
