The census is conducted every 10 years and provides valuable demographic data for central and state governments. It is the primary source of data at the village and town level on population characteristics, economic activity, education, housing, and other socio-cultural factors. The census data is used for reviewing development progress, monitoring government schemes, and planning for the future. It also forms the basis for reserving constituencies in parliamentary and local body elections. The National Population Register will create an identity database of usual residents to help target government benefits and services, and strengthen security. Both exercises are statutory and involve systematically counting and collecting information about the population.
