How will caste be recorded in second phase of Census 2027? | Explained
The Registrar General and Census Commissioner of India (RGCCI) notified 40 questions for the household schedule to be used in the second phase (Population Enumeration) of Census 2027.
Of these, 13 are new data fields that were not part of the Census 2011 questionnaire.
Caste will be recorded through an "open column" — enumerators will write down the caste name exactly as stated by the respondent, rather than selecting from a pre-populated dropdown list.
SC and ST status will continue to be recorded using existing official community codes, distinct from the open-column method used for the general caste question.
The methodology was tested in a pre-test conducted across multiple states and union territories before the final notification.
Census 2027's Two-Phase Structure
Census operations in India are conducted in two distinct phases: House Listing and Housing Census (which collects data on dwellings, amenities, and household assets) and Population Enumeration (which collects individual-level demographic, social, and economic data). The caste question falls in the second phase.
Key Details
- Phase I — House Listing and Housing Census: April 1, 2026 to September 30, 2026, conducted over a 30-day window as per each state/UT's convenience.
- Phase II — Population Enumeration: scheduled for February 2027, and this is the phase carrying the 40-question household schedule with the caste field.
- Snow-bound and difficult-terrain regions are typically enumerated earlier (in some cases from September) to avoid winter access issues.
- This two-phase structure has been used in Indian censuses since well before Independence and is distinct from a "digital census" pilot layer being introduced alongside paper/mobile-app enumeration.
The caste question is embedded specifically in the Phase II schedule now notified, meaning its actual field collection will only happen in the February 2027 population count, not during the ongoing housing phase.
The "Open Column" Method vs Fixed Caste Lists
An "open column" (or open-ended) survey field allows respondents to state an answer in their own words, which the enumerator transcribes verbatim, as opposed to a "closed" or "pre-coded" field where respondents choose from a fixed list of options. Census 2027 uses the open-column method for caste (excluding SC/ST, which retain official codified lists).
Key Details
- Open-column responses require post-enumeration coding and classification — a process where the Census organisation groups raw caste-name entries (including spelling variants, sub-castes, and synonyms) into standardised categories.
- This mirrors the approach used in the Socio-Economic and Caste Census (SECC) 2011, which also used open-ended caste entry and generated over 46 lakh raw distinct entries needing classification — a process that was never fully completed to the government's satisfaction.
- SC and ST categories avoid this problem because they are recorded against pre-existing statutory lists notified under Articles 341 and 342 of the Constitution.
- The risk with open-column methods is respondent self-reporting inconsistency (same caste written differently by different people) versus the risk with closed lists is incompleteness (a list can never capture every caste/sub-caste in India).
By choosing "open column" over a fixed dropdown, Census 2027 avoids the practical impossibility of pre-listing every caste and sub-caste nationally, but takes on the classification burden that made SECC 2011's caste data unusable.
Articles 341 and 342 — SC/ST Notification
SC and ST status is not self-declared in the open sense; it is recorded against lists that are constitutionally notified. Article 341 empowers the President to specify Scheduled Castes for a state/UT (via public notification, amendable only by Parliament); Article 342 does the same for Scheduled Tribes.
Key Details
- Article 341(1) and 342(1): President's notification, after consultation with the Governor in the case of a state, specifying the castes/tribes deemed Scheduled Castes/Scheduled Tribes for that state or UT.
- Article 341(2) and 342(2): Parliament may include or exclude any community from the notified list by law — the list cannot be varied by any other authority, a position affirmed by the Supreme Court in cases upholding the primacy of the Presidential notification process.
- Because SC/ST lists are state-specific, the same community may be listed as SC/ST in one state but not in another.
This constitutional machinery is why SC/ST can be recorded via pre-set codes in the Census 2027 schedule, while the general caste question (OBC and "General" category communities) requires the more improvised open-column approach.
- Total questions in Census 2027 household schedule: 40 (Census 2011 had 29).
- New data fields introduced: 13, including caste, Aadhaar, mobile number, bank accounts, voter ID, passport, and COVID-19 vaccination site.
- Caste recording method: open column (free-text, enumerator-transcribed) for general population; codified lists for SC/ST.
- Phase I (Housing Census): April 1–September 30, 2026.
- Phase II (Population Enumeration, with caste question): February 2027.
- SECC 2011 caste entries requiring classification: approximately 46.7 lakh distinct raw entries (never fully resolved/released).
- Constitutional basis for SC/ST notification: Articles 341 and 342.
