The Centre will allow residents to fill columns in the National Population Register (NPR) forms on their own through online mode, a month before door-to-door enumeration by Census officials starts. After filling the form online, residents will get a reference code that they could mention to the field enumerator at the time of her/his visit, according to a senior government official.
The NPR is a register of the usual residents of the country. It contains information collected at the local (village/sub-town), subdistrict, district, state and national level under provisions of the Citizenship Act, 1955 and the Citizenship (Registration of Citizens and Issue of National Identity Cards) Rules, 2003.
NPR was first done in 2010 and was later updated in 2015 when it was linked with the Aadhaar.
