Data hygiene: On the Census and enumerators

📌 Summary:

• Census 2027 enumerators in Rajasthan and Uttar Pradesh were reportedly advised to "revisit households and correct data discrepancies" and "not to select options that may show the government in a poor light"
• In Rajasthan, a circular from the Director of Census Operations asked officials to fix field-data discrepancies; in some cases enumerators were told to record data on assumptions
• Example: if a household lacks a toilet, enumerators were told to check for a nearby toilet and change the entry from "open defecation" to "access to latrine"
• Raises concern that legitimate re-verification is being misused to sanitise data and manage perceptions rather than reflect reality
• Episode exposes the gap between Open Defecation Free classifications (ODF, ODF Plus, ODF Plus Model) and ground reality
• Census 2027 phase 1 is the Houselisting and Housing Operation (HLO); total Census outlay is about ₹11,718 crore
• Editorial urges the Union government to raise enumerator allowances, sensitise the public to give correct information, and ensure data sanitisation is not done under the guise of re-verification
