The first complete census of India was conducted during the British colonial period, i.e., 1881 under the administration of Lord Mayo, who served as the Viceroy of India from 1869 to 1872.
The primary objective of conducting the census was to gather detailed demographic and socio-economic data about the population of British India. This comprehensive enumeration aimed to provide accurate and reliable information for administrative, governance, and policy-making purposes.
The methodology involved extensive field surveys and data collection carried out by enumerators.
Following the first census in 1872, the Census of India became a decennial exercise, with subsequent enumerations taking place every ten years.
Each successive census added new dimensions to the data collected, allowing for a more nuanced understanding of the changing demographic and socio-economic landscape of the country.
