India is preparing for a major transformation in its population survey process with the launch of Census 2027, marking the country’s first fully digital census exercise. In a landmark shift from traditional paper-based enumeration, the upcoming census will rely on mobile applications and online platforms for collecting household data.
Odisha is set to play a pioneering role in the digital transition, becoming one of the first regions in the country where residents can participate in the newly introduced self-enumeration facility.
Digital Census to Replace Paper-Based Surveys
Unlike previous decennial censuses, which relied heavily on paper forms and lengthy interviews conducted by enumerators, Census 2027 will operate on a completely digital infrastructure.
Field officials will record information using mobile applications during door-to-door visits, significantly reducing paperwork and improving data accuracy and processing speed.
To further streamline the process, the Ministry of Home Affairs (MHA) has introduced a web-based self-enumeration portal, enabling citizens to submit their household details online before the official enumeration begins.
Self-Enumeration Window for Odisha
Residents of Odisha will be among the earliest in India to access the digital portal, with the self-enumeration facility scheduled to open from April 1 to April 15, 2026.
This initial rollout phase will also cover several other regions, including:
- Andaman and Nicobar Islands
- Goa
- Karnataka
- Lakshadweep
- Mizoram
- Sikkim
- NDMC and Cantonment Board areas of Delhi
Nationwide Rollout Schedule
Following the first phase, the self-enumeration facility will gradually expand to other parts of the country according to a staggered schedule:
- April 5 – April 19, 2026: Gujarat, Dadra and Nagar Haveli, Daman and Diu
- April 10 – April 24, 2026: Uttarakhand
- April 16 – April 30, 2026: Andhra Pradesh, Arunachal Pradesh, Chandigarh, Chhattisgarh, Haryana and Madhya Pradesh
- April 17 – May 1, 2026: Bihar
- April 26 – May 10, 2026: Telangana
- April 30 – May 14, 2026: Punjab
- May 1 – May 15, 2026: Delhi (MCD), Maharashtra, Meghalaya, Rajasthan and Jharkhand
- May 7 – May 21, 2026: Uttar Pradesh
- May 17 – May 31, 2026: Jammu and Kashmir, Ladakh and Puducherry
- June 1 – June 15, 2026: Himachal Pradesh
Multilingual and User-Friendly System
The digital census platform has been designed to support 16 languages, ensuring accessibility for citizens across India’s diverse linguistic landscape.
The self-enumeration process has been structured to be simple and user-friendly, allowing residents to complete their details in a few steps.
Steps in the Self-Enumeration Process
The online census submission follows a straightforward digital workflow:
Authentication:
Users log in to the portal using their mobile number for verification.
Geotagging:
A digital map tool is used to pinpoint the exact location of the household.
Data Entry:
Respondents enter details related to household members, housing conditions and other census information.
ID Generation:
After submission, the system generates a unique Self-Enumeration ID.
Verification:
This ID must be shared with the census enumerator during the door-to-door verification stage, allowing authorities to confirm and officially include the submitted data.
A Major Step in India’s Administrative Modernisation
Officials believe that the digital census system will significantly improve efficiency, transparency and accuracy in data collection.
By enabling citizens to submit information themselves and allowing enumerators to verify it digitally, the government hopes to reduce errors, speed up data processing and simplify one of the world’s largest administrative exercises.
With Odisha among the first states to adopt the self-enumeration model, Census 2027 is expected to mark a new chapter in India’s governance and digital public infrastructure.
