Census trainers grapple with sensitive data collection on Aadhaar, caste

Census field trainers have identified Aadhaar data, caste information, age verification, and parental birthplace as key stumbling blocks in preparing enumerators for the next national census, according to observations from training sessions being conducted across the country.

The difficulties reflect broader sensitivities around personal information collection in India. Trainers have reportedly advised enumerators on strategies to encourage respondents to share Aadhaar details, with some suggesting the document could serve as proof of citizenship. However, senior Census officials have denied issuing any formal directives to promote Aadhaar data collection during enumeration exercises.

Questions related to caste remain particularly contentious, as do inquiries about respondents' ages and the birthplaces of their parents. Trainers have noted that respondents frequently express reluctance or suspicion when confronted with these queries, complicating the enumeration process.

The training challenges highlight the inherent tensions Census authorities face in balancing comprehensive data collection requirements with public concerns over privacy and the sensitive nature of certain demographic categories. How field teams navigate these obstacles may significantly impact the quality and completeness of census data collection.
