Census 2027 Pre‑test on Open‑Ended Caste Counting – Methodology and UPSC Implications

Census 2027: Pre‑test of Caste Counting Method The government has begun the second phase of the Census 2027 pre‑test on 6 July 2026 . It is being conducted in 16 states and union territories and will end on 20 July 2026 . A distinctive feature is an “open column” where respondents can write their caste, a practice that was also used in the 2011 SECC . Unlike the 2011 exercise, this time the caste count has statutory backing. Key Developments Open‑ended caste response will be recorded by enumerators on handheld devices. Government will finalise the counting methodology after the pre‑test. Expectation that a curated list of castes/sub‑castes will replace free‑text entries. Lessons drawn from the 2022‑23 Bihar caste survey, which used a pre‑loaded list. Important Facts The 2011 SECC generated more than 46 lakh distinct “caste names”, compared with only 4,147 entries in the 1931 Census – the last census to tabulate caste. The explosion of entries occurred because respondents entered surnames, sub‑castes, and clan names interchangeably, rendering the data unusable. In 2021, the Centre told the Supreme Court that SECC figures were too error‑prone for reservation decisions. To avoid a repeat, the current pre‑test proposes using digital handheld devices pre‑loaded with a curated list of castes . Enumerators will ask respondents their caste and then select the appropriate entry from the list. Mistakes may still occur, but the approach promises more reliable data, as demonstrated by the Bihar survey.
