Examine why civil society groups are demanding a unique coding system for castes before India's next census. What are the risks of an open-ended caste column?

Census 2027 will record caste for the whole population for the first time since 1931, captured electronically during the Population Enumeration phase [1]. Civil society groups argue that counting caste without a standardised code list will produce data too noisy to guide policy.

Why a unique coding system is demanded

• Parity with SC/ST practice: SCs and STs are enumerated against notified, coded lists, while OBC and General categories have no separate coded column; groups want every caste, along with its synonyms and regional variants, mapped to a unique code [5].
• Known messiness of caste lists: the Rohini Commission was expressly tasked with correcting "repetitions, ambiguities, inconsistencies and errors of spellings or transcription" in the Central OBC list — proof that unstandardised names already distort entitlements [3].
• Filling a long data vacuum: the Census has enumerated only SC/ST since 1951, and SECC 2011 caste figures were never released, leaving reservation and welfare targeting without dependable caste numbers [2].
• Fiscal and technical prudence: with an approved outlay of about ₹11,718 crore [4], a count that cannot be tabulated is seen as avoidable waste; coded fields also suit a digital, self-enumeration-enabled census [1].

Risks of an open-ended column

• Fragmentation: a single caste written in several spellings or dialect forms is tabulated as many small communities, shrinking its apparent share.
• False clubbing: identical or similar names borne by unrelated communities in different States get merged.
• Enumerator subjectivity: with no drop-down or verification step, recording depends on how the entry is heard and spelt.
• Deferred, contested classification: raw write-ins must be reclassified later by experts — the very bottleneck that stalled SECC 2011 [2] — weakening OBC sub-categorisation and commission work [3].

Standardised codes are therefore a data-quality safeguard, not a quota demand. Pre-testing a national caste code directory with State backward classes commissions, plus a transparent grievance route for omitted communities, would let Census 2027 deliver evidence-based social justice rather than a disputed headcount.
