In this phase, enumerators collect the following information:

Questions for Phase I were notified in January 2026. A full pre-test rehearsal took place in November 2025 across about 5,000 blocks in all States and UTs.
Phase II: Population Enumeration (PE)
Phase II takes place in February 2027. It collects detailed individual-level data. Additionally, the Cabinet Committee on Political Affairs (CCPA) has decided to include caste enumeration in this phase.
Phase II covers the following data points:
- Name, age, sex, and relationship to head of household

- Caste data (for the first time since 1931)
Census of India 2027: First-Ever Digital Census
Census 2027 is India’s first fully digital census. This makes it unique in the history of census in India. Enumerators use mobile apps to collect and submit data directly. There is no paper form or manual data entry at any stage.
Key Digital Features:
- Firstly, enumerators use a mobile app. They collect census data using smartphones.
- Moreover, the system supports 16 languages. Therefore, people can use the app and portal in Hindi, English, and other Indian languages.
- Additionally, officials use dashboard monitoring. They track census progress in near real-time.
- Furthermore, the system uses HLB mapping. It creates Houselisting Blocks with the help of a web mapping tool.
- In addition, the portal auto-generates records. So, it prepares some census data automatically.
- Finally, the government ensures data security. It takes all necessary steps to protect people’s data.
Self-Enumeration (SE): A New Feature
Self-Enumeration is a new and secure web-based facility. It allows citizens to fill their census details online before the enumerator’s visit. This gives households the flexibility to participate at their own convenience.
The Self-Enumeration portal is available at se.census.gov.in. Citizens must follow these steps:
Self-Enumeration Process – Step by Step
| Step | Action |
| Step 1 | Visit se.census.gov.in |
| Step 2 | Login using Mobile Number |
| Step 3 | Identify location on map |
| Step 4 | Fill Household Details |
| Step 5 | Submit Information |
| Step 6 | Receive unique SE ID |
| Step 7 | Share SE ID with Enumerator |
| Step 8 | Data confirmed and included in Census |
After successful submission, the system generates a unique Self-Enumeration ID (SE ID). Citizens must share this SE ID with the enumerator during the field visit.
