On January 22, 2025, the Registrar General and Census Commissioner of India (RG&CCI) issued a notification with 33 questions for the first phase of Census 2027. This phase, covering house listing and housing enumeration, is set to run from April 1 to September 30. The 33 questions cover key household details such as the materials used for flooring, walls, and roofing; number of married couples; head of the household's gender; cereal consumption; access to water and latrines; and ownership of vehicles and electronic devices. This builds on a previous list of 31 questions from 2020 that was delayed by COVID-19. Notably, the flooring, walls, and roofing question has been split into three separate parts. Mrityunjay Kumar Narayan, Registrar General of India, outlined these updates in the gazette notification. The official questions include basic details like building and house numbers, household size, and caste identity of the head of household. The survey will also ask about drinking water sources, lighting, cooking fuel, internet access, and possession of items like radios, TVs, phones, bicycles, and cars. A mobile number will be collected for Census communication only. Census 2027 aims to be India’s first fully digital Census. Around 30 lakh enumerators will collect data using mobile apps available on Android and iOS to improve accuracy. A pre-test of the first phase was done between November 10-30, 2025, in select locations. It collected data on 35 questions about housing materials, cereals consumed, water, cooking fuel, and married couples. The government has confirmed that caste data will be captured electronically later in the population enumeration phase. (With PTI inputs)
