The debate over method in caste enumeration is as important as the decision to enumerate. Discuss with reference to open-column versus coded approaches.

Census 2027 will be the first Census of independent India to count caste. The Cabinet Committee on Political Affairs approved this in April 2025 [2]. OBC groups are now protesting the design, not the decision: an open write-in column for everyone except SCs and STs [1]. The method of counting will decide whether the data can be used at all.

Why method matters

• Usability: SECC 2011 had an open caste field. It produced about 46 lakh caste, sub-caste, surname and gotra names, so the Cabinet set up a NITI Aayog-led expert group just to classify them [3].
• Policy stakes: OBC sub-categorisation (Rohini Commission), the Indra Sawhney 50% cap and Article 340 inquiries all need clean, comparable caste data.
• Trust: SECC caste tables were never made public. A disputed method could repeat that loss of trust.

Open-column approach

• Merits: respects self-identification; records small or unlisted communities; no government-drawn list decides who "exists" in the data.
• Limits: spelling variants, occupations entered as castes and local names lead to slow, closed post-count coding. This is how SECC failed [3]. A digital app [2] records only what is typed.

Coded (drop-down) approach

• Merits: unique codes for every caste (SC, ST, OBC, General) give standard data that can be tabulated quickly. Protesting groups demand exactly this [1], and a digital Census makes it possible [2].
• Limits: it needs one national master list, but Central and State OBC lists differ. Disputed entries in state surveys show that a poorly built menu can cause protests and leave communities out.

Way forward

• The Registrar General should publish a caste coding dictionary before counting begins. It can be built from Central and State lists and the SECC name variants [3].
• Hybrid design: respondents write freely while the app suggests matches. This keeps self-identification and cuts down variants.
• State Backward Classes Commissions should check how names map to codes in their state. Unmatched names should be published, with a fixed date for releasing the data.

The choice between open and coded methods decides whether caste enumeration produces evidence or controversy. A transparent hybrid, with codes fixed in advance and states consulted, can combine accuracy with self-identification. Done well, Census 2027 can turn the social-justice promise of Articles 15(4), 16(4) and 340 into well-targeted policy based on data.
