The Union Cabinet approved a proposal to update the National Population Register (NPR), which is linked to the Census. The exercise will cost Rs 8,500 crore, the government said. The Census Commission has said the objective of the NPR is to create a comprehensive identity database of every "usual resident" of the country. The database will have demographic details. A "usual resident", for the NPR, is a person who has lived in an area for at least six months or more, or a person who intends to live in an area for the next six months or more. It is mandatory for every "usual resident" of India to register in the NPR. The NPR, since it is linked to the Census, is seen as the first step towards a nationwide exercise to implement the National Register of Citizens (NRC). Though an NPR doesn't necessarily mean it's guaranteed there will be an NRC, it clears the path for a nationwide citizens' list. This is seen as one of the reasons why some states like West Bengal and Kerala, which are opposed to the NRC, have stopped work on the NPR. On this edition of The Big Picture we will take a closer look at the National Population Register.
