Form used in Census second phase rehearsal has ‘open column’ for caste

1. At a Glance

• The rehearsal for Phase-II (Population Enumeration) of Census 2027, run in 16 States/UTs from 6 July 2026, used a questionnaire with an "open column" for respondents to write their caste, rather than a pre-set drop-down list [1].
• This is the first time since 1931 that caste of all Indians (not just SCs/STs) is set to be enumerated in an Indian Census [1][2].
• The methodology choice — open write-in vs. selecting from a pre-defined list — is a live administrative and political debate with precedents in the SECC 2011 (open column, failed) and Bihar's 2022-23 caste survey (structured list) [1][S4].
• High UPSC relevance: touches Constitution/federalism (Census Act), social justice (OBC/SC/ST classification), and governance (data quality, digital enumeration).

2. Why in the News

• Rehearsal for Phase-II of Census 2027 began in 16 States/UTs on 6 July 2026 (Monday); it runs till 20 July 2026 [1].
• The Hindu (7 July 2026) reported that the trial questionnaire carries an "open column" for caste — signalling a likely (but not final) approach for the actual 2027 caste count [1].
• Officials clarified this is only a pre-test; the final questionnaire/methodology will be settled based on rehearsal feedback, with the final form expected by September 2026 [1].

3. Background & Evolution

• 1872–1931: British Indian censuses recorded caste of the entire population; discontinued for the general population after 1931 (only SC/ST enumerated from 1951 onward) [1].
• 30 April 2025: Cabinet Committee on Political Affairs (CCPA) decided to include caste enumeration in the forthcoming Census — first such decision in independent India for all castes [2].
• 2011: Socio-Economic and Caste Census (SECC), run by the Ministry of Rural Development outside the Census Act framework, used an open column for caste; caste data was never officially released as categories proved unusable (over 46 lakh distinct caste entries — duplicates, misspellings, sub-caste fragments) [2].
• 2022-23: Bihar conducted its own caste-based survey — notified 6 June 2022, data collection began 7 January 2023 (after Supreme Court dismissed challenge petitions), preliminary data released 2 October 2023, full report tabled in Bihar Assembly on 7 November 2023. Bihar used a pre-defined list of castes for respondents to choose from, not an open column [2].
• 1 April 2026: Census 2027 Phase-I (House Listing and Housing Census) commenced, running till September 2026 [2].
• February 2027: Phase-II (Population Enumeration, PE) — the phase carrying caste data — scheduled nationally [1][2].

4. Core Static Facts

5. Multi-Dimensional Analysis

Social

• First all-India, all-caste enumeration since 1931 could reshape the evidentiary basis for reservation policy, OBC sub-categorisation, and welfare targeting [1][2].
• Risk of caste fragmentation/proliferation in data (as seen in SECC 2011) undermines usability for policy unless categories are standardised [2].

Administrative / Governance

• Choice of "open column" vs. "pick-from-list" is not just technical — it determines data cleanliness, processing burden, and credibility of final caste counts.
• ORGI's classification/reconciliation mechanism (to standardise write-in entries against state OBC/SC/ST lists) is central to making an open-column approach viable this time, learning from SECC 2011's failure [2].
• Rehearsal-based, iterative questionnaire design (pre-test → feedback → final form) reflects standard Census methodology rigor.

Legal / Constitutional

• SC/ST enumeration has constitutional backing (Articles 341, 342 — Scheduled Castes/Tribes orders); enumeration of other castes has no equivalent constitutional mandate, making it a policy/administrative decision (2025 CCPA nod) rather than a constitutional requirement [2].
• Bihar's 2022-23 caste survey withstood Supreme Court challenge, establishing that state-level caste surveys are legally permissible — relevant precedent for the national exercise [2].

Political

• Caste census had been a long-standing opposition demand; CCPA's April 2025 decision to include it nationally reflects this political salience.
• Choice of methodology (open column vs. list) has downstream political implications — a list constrains recognised categories, an open column risks both undercounting/miscounting and giving voice to unlisted/sub-castes.

Historical

• Direct historical parallel: British-era censuses (up to 1931) enumerated caste; discontinuation post-Independence was a deliberate policy shift towards a "casteless" official data regime, now being reversed [1].

6. Recent Developments (last 12-18 months)

• 30 April 2025: CCPA decision to include caste enumeration in Census 2027 [2].
• 1 April 2026: Phase-I (House Listing and Housing Census) of Census 2027 begins [2].
• 6–20 July 2026: Rehearsal for Phase-II (Population Enumeration) conducted in 16 States/UTs; questionnaire trialled includes an "open column" for caste [1].
• Officials indicate final caste-recording methodology (open column vs. structured list) will be decided post-rehearsal, with the final questionnaire ready by September 2026 [1].

7. Prelims Hooks

• Census 2027 is the 16th Census of India and the country's first digital Census [1][2].
• It is the first Census since 1931 to enumerate caste for the entire population, not just SCs/STs [1][2].
• Cabinet Committee on Political Affairs approved caste enumeration in Census 2027 on 30 April 2025 [2].
• Census 2027 has two phases: House Listing & Housing Census (from 1 April 2026) and Population Enumeration (February 2027) [2].
• In Ladakh, snow-bound J&K, Uttarakhand and Himachal Pradesh, the Population Enumeration-linked rehearsal/phase concludes earlier (by 30 September) due to weather constraints [1].
• The Phase-II rehearsal (pre-test) ran in 16 States and UTs from 6 to 20 July 2026 [1].
• The rehearsal questionnaire's caste question had an "open column" — respondents write in their caste rather than choosing from a list [1].
• SECC 2011 (Socio-Economic and Caste Census) also used an open column for caste; conducted by the Ministry of Rural Development, not under the Census Act — its caste data was never officially released [2].
• SECC 2011 recorded roughly 46 lakh distinct caste names, rendered unusable due to duplication and spelling variants [2].
• Bihar's caste-based survey (2022-23) used a pre-defined list of castes for respondents to select from — contrasting with the open-column method [1][2].
• Bihar's caste survey notification was issued on 6 June 2022; data collection began 7 January 2023; final report tabled in the Bihar Assembly on 7 November 2023 [2].
• The nodal body for Census operations is the Office of the Registrar General & Census Commissioner of India (ORGI), under the Ministry of Home Affairs [2].
• The final caste-enumeration methodology/questionnaire for Census 2027 is expected to be settled by September 2026 [1].

10. Common Errors / Trap Areas

• Do not confuse SECC 2011 (Ministry of Rural Development, outside Census Act, caste data unreleased) with the decennial Census (Ministry of Home Affairs/ORGI, under Census Act, 1948) — a frequent mix-up.
• The rehearsal's "open column" is not confirmed as the final methodology — aspirants should not assume it as settled fact; final call depends on rehearsal feedback [1].
• Bihar's 2022-23 exercise is a state-conducted caste survey, not a Census exercise, and used a different (list-based) method — do not conflate with the national Census 2027 caste count.
• Remember Census 2027 caste enumeration covers all castes, not just SC/ST, which is the historical norm aspirants may default to.
• Note the correct nodal authority is ORGI under MHA, not the Ministry of Rural Development (which ran SECC) or MoSPI.
