Census 2027 to be India’s First Fully Digital Enumeration

India is set to conduct its first fully digital population census, with the initial phase beginning on 1 April 2026. Announced by the Registrar General and Census Commissioner, the exercise will mark the 16th census since inception and the eighth after Independence. It is expected to be the world’s largest enumeration exercise, involving over 3 million officials, including enumerators and supervisors, across the country.

Digital transformation and self-enumeration

For the first time, the census will be conducted using mobile applications for data collection. A major innovation is the introduction of self-enumeration, allowing citizens to submit their details through a secure online portal available in 16 languages. Households can generate a unique Self-Enumeration ID after submission, which will be verified during the enumerator’s visit. This hybrid model combines traditional field surveys with digital convenience and aims to improve data accuracy and participation.

Legal framework and reference dates

The census will be conducted under the Census Act, 1948 and the Census Rules, 1990. The reference date for most parts of the country is 1 March 2027. However, snow-bound regions such as Ladakh and parts of Jammu and Kashmir, Himachal Pradesh and Uttarakhand will have an earlier reference date of 1 October 2026, considering climatic constraints.

Two-phase census structure

The exercise will be conducted in two phases. Phase I, from April to September 2026, will focus on house listing and housing conditions, including amenities and assets. Phase II, scheduled for February 2027, will collect demographic, socio-economic and educational data. Enumeration of castes will also be undertaken during the second phase, making it a significant data collection effort for policy planning.
