The Census Act of 1948 (Act No. 37 of 1948) is a central legislation enacted by the Indian Parliament to provide the legal and administrative framework for conducting the decennial census in India. It received the President's assent on September 3, 1948, and was piloted by the then Home Minister, Sardar Vallabhbhai Patel. The Act was created to establish a permanent legal basis for census operations, unlike previous Census Acts which were confined to specific census years, and to ensure uniformity, accountability, and confidentiality in data collection. The first census of independent India in 1951 was conducted under the provisions of this Act.
The Act empowers the Central Government to declare its intention to take a census and to appoint a Census Commissioner and Directors of Census Operations. Key provisions include Section 3, which grants the Central Government the authority to take a census, and Section 4, which deals with the appointment of census staff. The Act makes it legally obligatory for every citizen to answer the census questions truthfully, and it provides penalties for giving false answers or obstructing the process. A crucial mechanism is the guarantee of confidentiality under Section 15, which stipulates that census records are not open to inspection and are not admissible as evidence in any civil or criminal proceeding, ensuring the data is used only for statistical purposes. The Act also allows the government to requisition premises, vehicles, or animals for census work, with provisions for compensation.
The Census Act of 1948 is intrinsically connected to the Constitution of India, as the population census is a Union Subject listed at serial number 69 of the Seventh Schedule under Article 246. It is also linked to the Office of the Registrar General and Census Commissioner, Ministry of Home Affairs, which was established in 1949 to deal with vital statistics and the census. The Act was amended in 1994 to update certain provisions, including the insertion of sections like Section 4A (staff of local authorities to be made available) and Sections 7A-7F (requisitioning of premises and vehicles).
