The Census 2027 will be conducted in two phases namely:

• Phase I – House Listing and Housing Census (HLO)
• Phase II – Population Enumeration (PE)

Phase I – House Listing and Housing Census (HLO)

House Listing and Housing Census (HLO) will start from May 22, 2026 to June 20, 2026 in Uttar Pradesh state along with option of Self-enumeration of 15 days period just before the 30 days period of house-to-house houselisting work i.e. May 7, 2026 to May 21, 2026. In this phase information about condition of houses, amenities available to the household and assets possessed by the household will be collected. Questions of the Phase I of the Census have been notified in January, 2026.

For self-enumeration, respondents can log into the SE portal using their mobile number and other basic details, and complete the Census schedule at their convenience. Upon successful submission, a unique Self-Enumeration ID (SE ID) will be generated which is to be shared with the enumerator during the field visit. Self-Enumeration option provides flexibility to fill the information at one’s own convenience before the enumerator’s visit. While enumerators will continue to make house to house enumeration in their allocated blocks as in the previous Censuses, Self-enumeration is an additional facility given this time to respondents.
