The Union Cabinet, chaired by Prime Minister Narendra Modi, on December 12, 2025 approved the scheme for the Conduct of Census of India 2027 with a financial outlay of ₹11,718.24 crore — the largest-ever investment in an Indian census. The 2027 census will be India's first fully digital census, using mobile applications for data collection (available on Android and iOS), a Central portal for real-time monitoring, and geospatial mapping for enumeration accuracy. The census will be conducted in two phases: Phase I — Houselisting and Housing Census (April–September 2026) — and Phase II — Population Enumeration (February 2027). Approximately 30 lakh field functionaries will be deployed. The most politically significant provision is the inclusion of caste enumeration for all communities — the first such comprehensive caste count since 1931 under British India. The Cabinet Committee on Political Affairs had approved caste enumeration in April 2025. Previously, only Scheduled Castes and Scheduled Tribes were enumerated by caste in post-independence censuses. The digital census will also capture housing data, living standards, and amenity access, providing a comprehensive socio-economic baseline. The National Population Register (NPR) update is not part of this exercise. The self-enumeration option allows citizens to fill in their own data through a portal, reducing enumerator burden. The data from Census 2027 will inform welfare schemes, delimitation of constituencies (after 2026 Delimitation Commission), and evidence-based policymaking across sectors.
