Confidentiality under the Census Act, 1948

The Census Act, 1948 protects individual census information from routine inspection, evidentiary use and unauthorised disclosure. Its confidentiality framework rests mainly on Sections 11 and 15, while preserving narrow statutory exceptions.

Protection against access and use in proceedings

Under Section 15, no person has a right to inspect any book, register or record prepared by a census officer, or any census schedule delivered under Section 10. Despite the law of evidence, entries in these materials are not admissible in civil proceedings or, ordinarily, in criminal proceedings.

• The evidentiary bar covers all civil proceedings.
• In criminal proceedings, the exception is a prosecution under the Census Act or another law for an act or omission constituting an offence under the Act.

Protection against unauthorised disclosure

Under Section 11, a census officer who discloses information received through, or for the purposes of, a census return without prior sanction of the Central or State Government commits an offence. This penal provision reinforces the confidentiality of individual returns.

• The protection concerns identifiable census returns and records, while census authorities may publish statistical information in aggregated form.
• The statutory scheme should not be described as an exceptionless secrecy rule because the Act itself recognises prior governmental sanction and limited use in offence-related prosecutions.
