• Decennial exercise, last full census in 2011.

The Census of India 2021 has been significantly delayed, primarily due to the COVID-19 pandemic and subsequent administrative reasons, impacting various policy decisions and resource allocations. Concurrently, there is an intensified national debate regarding the inclusion of caste-wise enumeration beyond Scheduled Castes and Scheduled Tribes.

The delay in Census 2021 has significant implications, as the data from the 2011 Census is now over a decade old and may not accurately reflect current demographic realities. This impacts the effective planning and implementation of welfare schemes, resource distribution to states, and the delimitation of electoral constituencies, potentially leading to misallocation of funds and skewed representation.
