The Registrar General and Census Commissioner of India (RG&CCI) announced 33 questions for the first phase of Census 2027. This phase, called Houselisting & Housing Census, will run from April 1 to September 30, 2026. This is two more questions than the 31 planned for the delayed Census 2021. The new notification separates the previous combined question about house materials into three: predominant materials used for the floor, walls, and roof. The government said this will be the first fully digital Census. Respondents will be able to self-enumerate through an online portal, which is yet to be announced. The second phase, Population Enumeration, is scheduled for February 2027. This will count caste and include new questions to be notified later. Census India posted on X: "The notification of questionnaire of Phase I of Census of India 2027 - Houselisting & Housing Census has been issued. The questionnaire for Phase II i.e. Population Enumeration will be notified in due course." The 33 questions cover details such as building and house numbers, house material types, house use and condition, household size, head of household’s name, sex, caste status, ownership, number of rooms, number of married couples, water and lighting sources, sanitation, cooking fuel, appliances owned, internet access, vehicles, main cereal consumed, and a mobile number for census communications only. A preparatory test was done from November 10-30, 2025, asking 35 questions in selected areas. It tested the census survey process and content. About 30 lakh officials including enumerators and supervisors will be deployed for the Census. They will collect data on their personal mobiles and receive an honorarium for this work on top of their regular duties.
