Census 2021

Census 2021 is India's delayed 16th decennial demographic exercise, conceptualized as the country's first digital census relying on mobile applications and self-enumeration portals for comprehensive data collection.

Under Current Affairs

• It serves as the statutory statistical foundation for evidence-based policymaking, fiscal devolution by Finance Commissions, and the future delimitation of electoral constituencies.
• The structural transition to a digital methodology modernizes public administrative capacity by reducing data processing latency and improving spatial data integration.
• The ongoing delay in execution creates a systemic data deficit that affects the accurate targeting of state welfare benefits and the estimation of socio-economic indicators.

UPSC evaluates this topic primarily through GS Paper I and GS Paper II, focusing on the governance consequences of relying on outdated demographic data for public policy. Questions frequently probe the administrative viability of digital enumeration methods, concerns regarding data privacy and infrastructure, and the policy dimensions surrounding demands for integrating socio-economic caste data into the census framework.
