Centre Issues Notification to Conduct Decennial Census in 2027
Source:Indian Express ↗

Why It Matters
The Census determines the statistical foundation for governance, welfare delivery, and political representation. For UPSC aspirants, understanding the direct linkage between the 2027 Census, the lifting of the delimitation freeze, and the realization of women's political reservation is critical for GS-2 (Polity and Social Justice) and GS-1 (Population dynamics).
Summary
The Centre has issued a notification scheduling the next decennial Census for the year 2027, formally shifting the timeline of the delayed 2021 exercise. This decision holds immense political and administrative significance. The completion of the 2027 Census will trigger the delimitation of parliamentary and state assembly constituencies, as the current constitutional freeze on altering constituency boundaries applies until the publication of the first census conducted after 2026. Furthermore, the implementation of the Nari Shakti Vandan Adhiniyam (Women's Reservation Act)—which promises 33% reservation for women in the Lok Sabha and state assemblies—is legally tethered to the completion of this upcoming delimitation. The delayed data collection also impacts the mapping of India's demographic dividend and the targeted delivery of welfare policies.
Key Points
- The Union Government has officially issued a notification to conduct the decennial Census in 2027, replacing the delayed 2021 Census.
- The Census was originally indefinitely postponed citing the COVID-19 pandemic and subsequent administrative delays.
- The 2027 Census is crucial as it will lift the freeze on delimitation (which is pegged to the first census after 2026), leading to the redrawing of Lok Sabha and State Assembly constituencies.
- The implementation of the Nari Shakti Vandan Adhiniyam, which mandates a 33% reservation for women in legislative bodies, is contingent upon the completion of this post-2026 delimitation exercise.

Cross-Topic Patterns
Delimitation vs. Fiscal Federalism
Impending delimitation raises concerns among southern states that their successful population control measures will inadvertently reduce their parliamentary representation and alter federal resource allocation.
