People are producers and consumers of resources. Population is the point of reference from which all other elements are observed. A census is an official enumeration of population, done periodically.
The Indian Census is the most comprehensive source of demographic, social and economic data.
It provides answers to three primary issues:
- Population size and distribution
- Population growth and processes of population change
- Characteristics or qualities of the population
India’s population as on March 2001 stood at 1,028 million, which is 16.7 per cent of the world’s population.
With a population size of 166 million people, Uttar Pradesh is the most populated state in India. Almost half of India’s population lives in the states of Uttar Pradesh, Maharashtra, Bihar, West Bengal and Andhra Pradesh.
