The Union Ministry of Home Affairs has officially notified that the next national census will be conducted in 2027, marking India’s first population count since 2011. The notification, issued on 16th June 2025, sets the reference date for the census at 00:00 hours on 1st March 2027 for most of the country. However, for snow-bound and remote regions such as Ladakh, Jammu and Kashmir, Himachal Pradesh, and Uttarakhand, the reference date will be 1st October 2026, to account for logistical challenges in those areas.

This will be the 16th census since the exercise began in India and the 8th since Independence. The census, which was originally scheduled for 2021 but delayed due to the COVID-19 pandemic and other factors, will now be held after a gap of 16 years. The notification supersedes the earlier 2019 order that had set the framework for the postponed 2021 census.

Two-Phase Exercise with Digital Transformation

The 2027 census will be conducted in two major phases. The first phase, known as the Houselisting Operation (HLO), will begin in October 2026 for the snow-bound regions and in early 2027 for the rest of the country. This phase will collect data on housing conditions, household assets, and access to amenities. The second phase, called Population Enumeration (PE), will start from 1st March 2027, gathering detailed demographic, socio-economic, and cultural information about every individual in the country.

For the first time in Indian history, the entire census will be carried out digitally. Enumerators—primarily school teachers—will use mobile applications and handheld devices to record data. A self-enumeration option will also be available, allowing households to fill in their own details online through a secure government portal. This digital move is expected to speed up the process, reduce manual errors, and enable near real-time monitoring and quality checks.

The government has assured that stringent data security measures will be in place at every stage—collection, transmission, and storage—to protect the privacy of citizens.

Historic Caste Enumeration After 90 Years

A significant feature of Census 2027 is the inclusion of caste enumeration for all communities, something not done on a national scale since 1931. This means that, apart from the usual demographic and socio-economic data, the census will collect detailed information on caste for every individual, not just for Scheduled Castes (SC) and Scheduled Tribes (ST) as in previous decades.

However, the government has clarified that there will be no consolidated Other Backward Classes (OBC) category; all castes will be listed individually. The inclusion of caste data is seen as a response to long-standing demands from various political and social groups, and is expected to influence future policy planning and welfare schemes.

Political and Administrative Implications

The timing of the census is crucial, as it will provide the data needed for the long-awaited delimitation of parliamentary and assembly constituencies. According to the 84th Constitutional Amendment, the first census after 2026 will be used as the basis for redrawing constituency boundaries and implementing the 33% women’s reservation in the Lok Sabha and state assemblies, as mandated by the 128th Constitutional Amendment.

The census results are expected to be processed and provisional data released within days of enumeration, with final data likely available within six months. This could pave the way for the delimitation process to begin before the 2029 general elections, although some political leaders, especially from southern states, have expressed concerns about possible changes in parliamentary representation based on population figures.

Modernised Process and Data Collection

The digital census will introduce several technological upgrades compared to the 2011 exercise. Enumerators will use GPS-enabled devices for accurate mapping, and a new coding system will standardise responses to minimise errors and speed up data processing. The questionnaire will cover 34 columns in the house-listing phase and 28 columns in the population enumeration phase, capturing extensive information on housing, assets, language, occupation, education, religion, and now caste.

A total of about 34 lakh enumerators and supervisors, along with around 1.3 lakh census officials, will be deployed across the country to ensure smooth conduct of the exercise.

Census 2027 marks a major leap for India, not only as the first digital census but also as the first to count caste for all communities in nearly a century. The data collected will shape government policies, resource allocation, and political representation for years to come. With the process now formally notified, preparations are underway to ensure that this massive national exercise is completed efficiently and securely.
