What This Article Covers

1.The 2027 Census questionnaire has 40 questions — a significant departure from previous censuses — seeking details like Aadhaar, voter ID, passport, mobile number, bank accounts, parents' names, and nationality.

2.Experts argue these personal identifiers are not useful for generating statistics and may be used to update the NPR/NRC, violating the UN Fundamental Principles of Official Statistics on confidentiality.

3.Concerns include enumerator burden, respondent fatigue, ambiguous phrasing ('if available'), and potential misuse of data by non-census functionaries.

The Big Picture
Prelims · HighMains · High

The Census 2027 questionnaire includes 40 questions asking for personal identifiers like Aadhaar, voter ID, passport, mobile, and bank accounts — data of no statistical value. Critics fear this is a backdoor attempt to update the National Population Register (NPR) and eventually the National Register of Citizens (NRC), bypassing state consent and violating confidentiality principles. This has serious implications for privacy, federalism, and the integrity of the census exercise.
