The decadal exercise — the 15th headcount of India’s population since 1872 — is undertaken to create a database on demography, economic activity, literacy and education, housing and household amenities, urbanisation, fertility and mortality, social structure, language, religion and migration. Some 8,000 million tonnes of paper have been used for the exercise. The census is the only source of credible data base in India that the government uses to formulate its policies.
