India’s census in 2021


India’s next census, the world’s largest enumeration of population, beginning in 2021 will be a "digital” exercise as a mobile app will be used to collect data, Home Minister Amit Shah said on Monday. He also proposed the idea of a multipurpose ID card for every citizen which includes passport, and the voter card. India's last census was carried out in 2011 when the country's population stood at 121 crore. Census 2021 will be the world's largest enumeration exercise, an official said.

"A mobile app will be used in Census 2021. It will be a transformation from paper census to digital census," Shah said at an event in Delhi to lay the foundation stone of the office of the census authority. He proposed one card for all utilities like Aadhaar, passport, bank account, driving license, voter ID card. This is a potential," he said.

The Home Minister said there should also be a system that when a person dies, the information is updated in the population data automatically. An app is being developed indigenously for collecting the data and in Android phones, Shah said adding Rs. 12,000 crore will be spent on the country's first digital census. A total of 33 lakh enumerators, the persons who conduct door-to-door counting, would be mobilized for data collection.
