India is set to conduct its first digital and caste-inclusive census in 2027, marking a historic shift in how the country’s population data is collected and used. The Union Home Ministry officially notified the schedule and methodology on June 16, 2025, making this the first nationwide caste enumeration since 1931 and the first census since 2011.
Key Features of the 2027 Census
1. Two-Phase Census Operation
- Phase 1 (Houselisting Operation): Begins October 1, 2026. Collects data on assets, family income, housing conditions, and amenities. For the first time, this phase will be conducted digitally, allowing respondents to answer queries from home via a dedicated portal or mobile app.
- Phase 2 (Population Enumeration): Starts March 1, 2027 (reference date for most regions; October 1, 2026, for snow-bound areas). This phase gathers demographic, socio-economic, cultural, and personal data—including caste details for every individual.
2. Digital-First Approach
- Self-Enumeration: Households can log into a government portal or use a mobile app to fill out their details, generating a unique ID for verification by enumerators.
- Mobile Apps & Real-Time Monitoring: Enumerators will use handheld devices preloaded with the census app, enabling real-time data collection, error alerts, and GPS/geotagging for accuracy.
- Languages: Apps are available in English and 15 regional languages to ensure inclusivity.
3. Caste Enumeration
- For the first time since 1931, caste data will be collected for all communities, not just SC/ST, making it a landmark exercise for social policy and welfare.
- The inclusion of caste data is expected to influence future welfare policies, reservations, and governance structures.
4. Policy Implications
- Women’s Reservation Bill: The census paves the way for the implementation of the Women’s Reservation Bill, which reserves one-third of seats in the Lok Sabha and state assemblies for women. This can only take effect after the census and a subsequent delimitation exercise.
- Delimitation: The census will be the basis for redrawing electoral constituencies, a process frozen since 1971 and now scheduled to resume after 2027.
- National Population Register (NPR): The census will also update the NPR, which was cleared by the cabinet in 2019.
5. Budget and Manpower
- Estimated Budget: Rs 4,000 crore (as per Cabinet Committee on Economic Affairs).
- Enumerators: Approximately 30–34 lakh personnel, primarily school teachers, will be deployed for the exercise.

Conclusion
