The Registrar General and Census Commissioner of India (RGCCI) is a statutory office under the Ministry of Home Affairs (MHA), Government of India. Established in 1949, it was created to provide a permanent institutional framework for conducting the decennial census and managing vital statistics, moving away from the ad-hoc census organizations used during the British Raj.
The office derives its primary authority from the Census Act, 1948, which empowers the Central Government to appoint a Census Commissioner to supervise the taking of the census. Furthermore, under the Registration of Births and Deaths (RBD) Act, 1969, the RGI acts as the central authority to coordinate and unify the Civil Registration System (CRS) across all States and Union Territories.
Key functions include conducting the Decennial Census, the world’s largest administrative exercise, and managing the Sample Registration System (SRS), which provides annual estimates of fertility and mortality rates. Crucially, under the Citizenship Act, 1955 and the Citizenship (Registration of Citizens and Issue of National Identity Cards) Rules, 2003, the RGI is designated as the National Registration Authority, responsible for maintaining the National Population Register (NPR).
For the UPSC exam, this institution is significant for GS Paper I (Population and Associated Issues) and GS Paper II (Statutory Bodies and Governance). It is central to policy-making, delimitation of constituencies, and the ongoing discourse surrounding the National Register of Citizens (NRC). Related concepts include the Linguistic Survey of India, the Socio-Economic and Caste Census (SECC), and the Mother Tongue Survey of India (MTSI).
