The Census Act 1948: Duties, Penalties and Confidentiality

Legal framework: Census 2027 is conducted under the Census Act, 1948 (Act No. 37 of 1948) and the Census Rules, 1990, as amended by the Census (Amendment) Rules, 2022. Census is a Union subject — entry 69 of the Union List, Seventh Schedule of the Constitution. The Census Commissioner of India is appointed by the Central Government under Section 4(1); the Office of the Registrar General and Census Commissioner of India functions under the Ministry of Home Affairs.

Duty to answer: under Section 8(2), every person asked a census question 'shall be legally bound to answer such question to the best of his knowledge or belief' (official Goa FAQ quoting the Act). Answering is compulsory and participation mandatory. Penalty: Section 11(1)(d) makes refusing to answer, or giving a false answer, an offence punishable with a fine that 'may extend upto one thousand rupees' (Rs 1,000). Public obligations under the Act (even for those self-enumerating online): (a) allow census staff entry to the house; (b) allow the painting/writing of the census number on the house; (c) give correct information to the best of knowledge and belief.

Confidentiality — Section 15: personal information given in the census is treated as strictly confidential; census records are 'not open to inspection nor admissible in evidence' in any court; per the PIB Backgrounder, individual data 'cannot be made public under the RTI Act, used as evidence in any court of law, or shared with any institution.' Only aggregate data at administrative levels (State, district, sub-district, village/town) is published.

No proof or documents can be demanded from respondents — everything is recorded as declared. Census (Amendment) Rules, 2022: issued under Section 18(1) of the Act, these amendments legally enabled the digital census by (1) defining 'self-enumeration' as 'filling-up, completion and submission of census schedule by respondents themselves' and permitting it, and (2) allowing census schedules in 'electronic form' as defined in Section 2(1)(r) of the Information Technology Act, 2000 (Legitquest text of the 2022 Rules; the Act text is on India Code).

Digital-era security additions layered on the statute: end-to-end encryption, storage in Critical Information Infrastructure (CII)-designated certified data centres, ISO/IEC 27001:2022 compliance, and regular third-party security audits (PIB Backgrounder). Census functionaries are themselves census officers under the Act and bound by its secrecy provisions; enumerator appointment is done by State/District administration 'as per the provisions of Census Act 1948 and Rules thereof.' RGI assurance at the April 1, 2026 launch: Registrar General Mritunjay Kumar Narayan 'assured that necessary measures for data security have been taken' (newsonair).
