Census: Six months to go, government explores how to count caste
With months to go before the population enumeration phase of Census 2027, officials are finalising the method to be used for recording caste details of every citizen
This will be the first time caste data for all communities (not just Scheduled Castes and Scheduled Tribes) is collected in a nationwide Census since 1931
Two broad methodology options have been under consideration: an "open column" format where a respondent's caste name is recorded exactly as self-declared, versus use of a pre-compiled, verified list of caste names from which a respondent selects
A pre-test/rehearsal exercise in select areas trialled the open-column, self-declaration approach, with a Self-Enumeration ID (SE ID) generated online and later confirmed by a field enumerator
Census 2027 is being conducted under the Census Act, 1948, in two phases, with the population enumeration reference date fixed at 00:00 hours on 1 March 2027 (1 October 2026 for Ladakh, snow-bound Jammu & Kashmir, Uttarakhand and Himachal Pradesh regions)
Constitutional and Statutory Basis of the Census
Conducting a population census is a Union subject under Entry 69 of the Union List (Seventh Schedule), which Parliament legislates on using its exclusive power under Article 246(1). The operational law is the Census Act, 1948, which authorises the Union government (through the Office of the Registrar General and Census Commissioner of India, under the Ministry of Home Affairs) to conduct the decennial census and makes furnishing of information to census officials compulsory, while individual data on named persons is kept confidential under Section 15 of the Act.
Key Details
- Census is Entry 69, Union List, Seventh Schedule; Article 246(1) gives Parliament exclusive power to legislate on Union List subjects
- Census Act, 1948 is the governing statute; census-taking is administered by the Registrar General of India (Ministry of Home Affairs)
- India's census has been conducted decennially since 1881 (uninterrupted since 1881); Census 2021 was postponed due to the COVID-19 pandemic, making Census 2027 the 16th Census of independent India (post-1951 series) and the first to be conducted digitally
- Individual-level responses are confidential and cannot be used as evidence in any proceeding, under Section 15 of the Census Act, 1948
Because the entire exercise runs on the Census Act's authority, the choice of how caste is recorded (open column vs. fixed list) is an administrative/implementation decision by the Registrar General's office, not something requiring fresh legislation — the debate is about survey design, not legal power.
Caste Enumeration: 1931 Census vs. SECC 2011 vs. Census 2027
The last time the Census officially counted caste for all communities was in 1931, during British colonial rule; independent India's censuses recorded only Scheduled Caste and Scheduled Tribe populations, not the full caste spectrum. The 2011 Socio-Economic and Caste Census (SECC) attempted to fill this gap outside the regular Census framework but its caste data was never officially released, as the open-ended, non-standardised format it used generated over 46 lakh distinct caste, sub-caste, surname and clan entries — a dataset the government and the Supreme Court both found too error-ridden to be usable for policy purposes.
Key Details
- 1931 Census: last full caste count of British India across all communities
- Post-1951 Censuses record only SC/ST population counts, not other caste categories
- SECC 2011 was conducted by ministries outside the Registrar General's office, without the Census Act's standardised protocol; it returned over 46 lakh caste-name variants due to its open-ended, unstandardised format, and its caste data was never officially published
- The Union Cabinet decided in 2025 to include caste enumeration as part of the main Census 2027 exercise, giving it the legal and administrative rigour of the Census Act framework (rather than a separate survey like SECC)
The government's methodology debate is a direct response to the SECC 2011 experience — the "open column" pre-test is designed to allow self-declaration while avoiding the uncontrolled proliferation of caste-name variants that made the 2011 data unusable, though a coded/standardised list remains an alternative under discussion.
Census 2027 Design: Digital, Two-Phase Structure
Census 2027 is India's first digital census, conducted using a mobile app/online self-enumeration portal in addition to traditional door-to-door enumeration, and is structured in two phases as with previous censuses: House-listing and Housing Census (Phase I), followed by Population Enumeration (Phase II).
Key Details
- Phase I (House-listing and Housing Census): a 30-day district-wise field exercise (with a preceding 15-day self-enumeration window), conducted between April and September 2026
- Phase II (Population Enumeration): conducted in February 2027, with the reference date/time as 00:00 hours, 1 March 2027 (1 October 2026 for high-altitude/snow-bound areas)
- Self-Enumeration ID (SE ID): generated when a respondent fills details online in advance; a field enumerator subsequently visits to verify and confirm the data
- Caste enumeration is embedded within Phase II's population schedule, alongside existing demographic, socio-economic and housing parameters
Because caste enumeration is folded into the regular Population Enumeration phase (Phase II, from February 2027), the methodology for recording caste has to be finalised and field-tested well before that phase begins — explaining why the design choice is being worked out in the months preceding it.
- Last full caste count of British India: 1931 Census
- SECC 2011: produced over 46 lakh distinct caste/sub-caste/surname categories; caste data never officially released
- Census is Union List Entry 69 (Seventh Schedule); legislated under Article 246(1); governed by the Census Act, 1948
- Census 2027 Phase I (House-listing): April–September 2026; Phase II (Population Enumeration): February 2027
- Population Enumeration reference date: 00:00 hours, 1 March 2027 (1 October 2026 for Ladakh, snow-bound J&K, Uttarakhand, Himachal Pradesh)
- Census 2027 is the first digital census of India and the first Census since 1931 to enumerate caste for all communities
