Background & Context

The Census of India has been conducted every decade since 1881, becoming a cornerstone for administrative and policy decisions by detailing demographic, economic, and social characteristics of the population. The 2021 census was deferred due to the COVID-19 pandemic and electoral processes, making the 2027 census crucial for updated data.

Integrating modern digital technology aims to enhance enumeration accuracy, speed, and data security. Comprehensive caste enumeration will provide granular data to inform social justice policies and reservation frameworks, reflecting India's complex caste dynamics.

The census data underpin key functions such as resource allocation, socio-economic welfare planning, delimitation of electoral constituencies, and support evidence-based policymaking.
