CLAT GK + Polity / Governance
India has begun the world’s largest census exercise. Phase 1 — the Houselisting and Housing Census (HLO) — of Census 2027 commenced across the country from April 16, 2026, in eight pilot States/UTs (Odisha, Goa, Karnataka, Mizoram, Sikkim, Lakshadweep, Andaman & Nicobar, NDMC/Delhi Cantonment), with a phased rollout to follow nationally. This will be India’s first-ever fully digital census: enumerators carry a mobile app, and citizens can self-enumerate online via se.census.gov.in.
The Indian Express’s ground report from Banamalipur, Khordha district, Odisha, profiles Sarmishta Sahoo, a 25-year-old enumerator going door-to-door in 35°C heat with ORS packets and a mandatory ID card. Each enumerator is averaging ~256 buildings; over 1 lakh enumerators (mostly schoolteachers) have been deployed nationally. Heatstroke deaths of enumerators in Dhenkanal and elsewhere — 5 deaths reported so far — have triggered a Standard Operating Procedure (SOP) on heat safety and ID-carry.
What Happened
HLO captures details on housing conditions and household amenities — 33 questions in Phase 1, notified in January 2026. It is the precursor to Phase 2 — Population Enumeration (Feb–Mar 2027) with the reference moment fixed at 00:00 hours on 1 March 2027. Census 2027 will also be the FIRST since 1931 to formally enumerate caste — a politically charged restoration with deep policy and reservation implications.
The Background
Census in India is decennial since 1881 (under W.C. Plowden); the 1872 round was a non-synchronous trial. The 2021 census was indefinitely postponed in March 2020 because of COVID-19, breaking a 140-year unbroken decennial sequence. Census 2027 thus arrives 16 years after 2011 — making it both delayed and historically significant.
Constitutional & Legal Framework
- Article 246 + Seventh Schedule, Union List Entry 69 — “Census” is a Union subject; only Parliament can legislate.
- Census Act, 1948 — governs conduct, enumerator powers, penalties for refusal/false answers, and absolute confidentiality of returns.
- Article 82 — readjustment of Lok Sabha seats after each census; relevant for the post-2026 delimitation debate.
- Registrar General & Census Commissioner of India (RGCCI) — under the Ministry of Home Affairs (MHA); the constitutional authority for census conduct.
- Information Technology Act, 2000 — relevant to data security of digital enumeration and self-enumeration portal.
Why This Matters
Census data drives delimitation of constituencies, reservation matrices, scheme targeting (PMAY, Jal Jeevan, MGNREGA), Finance Commission devolution, and India’s BIMSTEC/G20 demographic narrative. The 2027 caste-enumeration restoration will reshape political and policy debates on quota expansion. The digital format also raises new data-protection questions under the DPDP Act 2023.
CLAT 2027 — Why You Must Know This
Census 2027 is a near-certain CLAT GK and Legal-Reasoning topic. Expect: (i) Article 82 + Article 81 questions on delimitation freeze; (ii) Census Act 1948 confidentiality vs RTI; (iii) Concurrent vs Union List placement; (iv) Articles 14 & 16 implications of caste enumeration; (v) federal-cooperation questions (state IDs, schoolteacher deployment).
