India's Census 2027 will be the first fully digital census, introducing self-enumeration that allows citizens to provide household details online. This initiative, starting in April 2026, aims to enhance the accuracy of data collection and streamline the process. The census is divided into two phases: Phase I, from April to September 2026, will gather housing-related information, while Phase II, scheduled for February 2027, will collect individual details such as age, sex, and education. The self-enumeration process is optional but highly recommended, as it offers privacy and saves time for both citizens and officials. The official self-enumeration portal will be accessible only within India and requires an internet connection, ensuring that all data is encrypted and securely stored. Participation in the census remains mandatory under the Census Act, 1948, which is conducted every ten years to aid in planning and resource allocation.
