Census: The Indian Census is one of the largest administrative exercises undertaken in the world. Census Act 1948 provides a legal basis for it. The Census of India is conducted once in a decade, using an extended de facto canvasser method. Under this approach, data is collected from every individual by visiting the household and canvassing the same questionnaire all over the country, over a period of three weeks. The count is then updated to the reference date and time, by conducting a revision round. In the revision round any changes that occur on account of births, deaths, and migration between the time of enumerator’s visit and reference date time are noted and record updated.
