While the process of NPR and Census will begin simultaneously, the two databases are not same.
The decennial census is the largest single source of a variety of statistical information on different characteristics of the people of India.
While NPR only contains demographic information, more details are required for census like information on demography, economic activity, literacy and education, and housing and household amenities besides others.
The census is the basis for reviewing the country’s progress in the past decade, monitoring the ongoing schemes of the government and plan for the future.

The census provides detailed and authentic information on demography, economic activity, literacy and education, housing and household amenities, urbanisation, fertility and mortality, scheduled castes and scheduled tribes, language, religion, migration, disability besides others.
The enumerators also collect data related to cultivators and agricultural labourers, their sex, occupational classification of workers in the non-households industry, trade, business, profession or service by class of worker and sex.
There will be a detailed survey on gender and literacy rate, a number of towns, slum households and their population.
Information is also collected on sources of potable water, energy, irrigation, method of farming, whether a house is a concrete, thatched or others.
For snow-bound areas in Jammu and Kashmir, Himachal Pradesh and Uttarakhand, the reference date will be October 1, 2020.
With a history of more than 130 years, this reliable, time tested exercise has been bringing out a veritable wealth of statistics every 10 years, beginning from 1872 when the first census was conducted in India non-synchronously in different parts.
