Examine the implications of reintroducing caste enumeration in the census.

Acting on the Cabinet Committee on Political Affairs decision of April 2025, Census 2027 will record caste for every individual — the first such count since 1931, since post-Independence censuses enumerated only SCs and STs [1]. The implications run well beyond statistics, into welfare design, federal politics and data governance.

Supplying the missing denominator

• Backward-class reservations and scheme targeting are currently fixed without any official count of the groups concerned; caste tables would give policy a measurable base for the first time in nearly a century [1].
• Group size underpins constitutional claims: the NCST's recommendation to bring Ladakh under the Sixth Schedule rests on its tribal population exceeding 97% [5].
• Digital capture with self-enumeration should compress the gap between collection and publication [2].

Political and social consequences

• Every published caste share becomes a claim for a larger quota. After its own caste survey, Bihar enacted Act 18 of 2023, raising reservation in educational institutions to 65%, beyond the 50% ceiling [4].
• Counting caste risks hardening identity rather than dissolving it. Crucially, size is not backwardness — caste tables read without income, education and occupation columns can justify quotas for groups that are not the worst off.

Administrative and data-governance risks

• The SECC 2011 precedent is cautionary: open-ended recording produced roughly 46 lakh caste, sub-caste, synonym and surname entries, requiring a Cabinet-approved expert group under NITI Aayog to classify them — and its tables were never released [3]. A free-text field in the census app would repeat this; a State-wise standardised caste directory is the corrective.
• Section 15, Census Act 1948 keeps individual records outside the RTI Act and inadmissible in court, backed by end-to-end encryption and Critical Information Infrastructure hosting [2].

Caste enumeration is therefore necessary but not sufficient: its worth depends on classification discipline and timely release. Publishing caste tables alongside socio-economic indicators, on a pre-announced date, would convert a contested count into evidence-based targeting — advancing the substantive equality promised by Articles 15(4) and 16(4).
