Caste Census 2027: Full list of questions to be asked in the second phase of Census
The Population Enumeration (PE) phase — the second and main phase of Census 2027 — will record caste identity for every resident, not only Scheduled Castes and Scheduled Tribes, for the first time since 1931.
The Registrar General and Census Commissioner of India has finalised roughly 40 questions for the Population Enumeration schedule, covering demographic, caste, religious, economic, and digital-identity details.
The PE phase begins in snow-bound areas of Ladakh, Jammu and Kashmir, Himachal Pradesh, and Uttarakhand from mid-to-late August 2026, with the rest of the country covered in February 2027.
Census 2027 is being conducted digitally for the first time, using a mobile application and a central monitoring portal, with a self-enumeration option available to citizens ahead of door-to-door enumeration.
Constitutional and statutory basis of the Census
Conducting the Census is a Union subject, and the exercise is governed by a dedicated central statute rather than being constitutionally mandated in its procedural details.
Key Details
- "Census" falls under Entry 69 of the Union List (Seventh Schedule), read with Article 246, giving Parliament exclusive power to legislate on it.
- The Census Act, 1948 is the governing statute; it empowers the Central Government to notify a Census and vests the Registrar General and Census Commissioner of India (under the Ministry of Home Affairs) with administrative control.
- Section 15 of the Census Act guarantees confidentiality — individual Census records cannot be disclosed and are inadmissible as evidence in any court proceeding.
- The last full Census was in 2011; Census 2021 was postponed due to the COVID-19 pandemic, making Census 2027 the 16th Census of independent India and the first in 16 years.
The Population Enumeration questionnaire being finalised now operates under this statutory (not constitutional) framework, which is why its content — including the caste question — can be modified by executive notification without a constitutional amendment.
Delimitation freeze and Article 82 — why Census 2027 matters beyond headcounts
Article 82 requires Parliament to readjust Lok Sabha seat allocation and constituency boundaries after every decennial Census through a Delimitation Act. This process has been frozen for decades, and Census 2027 is significant as the trigger Census for the freeze's expiry.
Key Details
- The 42nd Amendment Act, 1976 first froze delimitation at the 1971 Census figures to avoid penalising states that had achieved better population control.
- The 84th Amendment Act, 2001 extended this freeze until the first Census taken after 2026 — meaning seat allocation among states will finally be revisited based on Census 2027 population data.
- Internal boundary readjustment (without changing total seat numbers) was permitted based on the 2001 Census under the 84th and 87th Amendment Acts, 2001/2003.
- Delimitation is carried out by a Delimitation Commission under the Delimitation Act (most recently the 2002 Act for the 2001 Census-based exercise); its orders are not open to judicial challenge (Article 329(a) read with the Delimitation Act).
Because Census 2027 is the first Census after the 84th Amendment's 2026 cut-off, its final population figures will determine the basis for the next delimitation exercise — raising the stakes of accuracy and timing for the Population Enumeration phase now being rolled out.
Caste enumeration and Social Justice — SECC 2011, 1931 Census, and Mandal-era jurisprudence
India's Census has not counted caste for the general population since 1931; post-independence Censuses recorded only SC/ST status. Caste Census 2027 marks a return to comprehensive caste enumeration, intersecting with the constitutional debate on reservation ceilings and OBC sub-categorisation.
Key Details
- The 1931 Census under British India was the last to publish a full caste-wise population count for all communities.
- The Socio Economic and Caste Census (SECC) 2011 collected caste data as part of a separate exercise (not the decennial Census), but its caste data was never officially released due to inconsistencies in caste names.
- The Constitution (Ninety-third Amendment) Act, 2005 inserted Article 15(5) enabling reservation for socially and educationally backward classes (including OBCs) in educational institutions; Indra Sawhney v. Union of India (1992) capped total reservation at 50% (subject to exceptions) and distinguished the "creamy layer" among OBCs from SC/ST reservation.
- The Population Enumeration schedule now includes a dedicated caste column for all residents (not just SC/ST), alongside religion, disability, mother tongue, migration, education, and financial-inclusion (bank account, Aadhaar) details.
The finalised PE questionnaire operationalises the caste enumeration decision, and the resulting nationwide caste data — unlike the unreleased SECC 2011 figures — is expected to directly inform future policy debates on OBC sub-categorisation and reservation ceilings.
- Population Enumeration (PE) is Census 2027's second phase; roughly 40 questions have been finalised for this schedule.
- PE begins August 17, 2026 (self-enumeration) in snow-bound areas of J&K, Ladakh, Himachal Pradesh, and Uttarakhand, with door-to-door enumeration from September 1-30, 2026; the rest of India is covered in February 2027.
- The Census Reference Moment is 00:00 hours, October 1, 2026 (for snow-bound areas), with a revisional round October 1-5, 2026.
- Governing statute: Census Act, 1948; subject falls under Entry 69, Union List (Article 246).
- Last full caste enumeration of the general population: 1931 Census.
- 84th Amendment Act, 2001 froze delimitation until the first Census after 2026 — making Census 2027 the trigger for the next delimitation exercise under Article 82.
- Census 2027 is the 16th Census of independent India, delayed from its usual 2021 schedule, and the first to use a digital, app-based enumeration process.
