Administrative / Governance - First census using mobile apps for enumerators with paperless data capture [S2][S4]. - Self-enumeration reduces enumerator load, enables real-time validation [S4]. - States/UTs choose the 30-day window per local convenience — cooperative federalism in scheduling [S2].

Social - Caste enumeration after nearly a century (last full caste census 1931); will feed reservation-policy debates [S4]. - Will update SC/ST/religion data, gender ratio, literacy — basis for delimitation post-2026.

Legal / Constitutional - Backed by Census Act, 1948 (Union List Entry 69 of 7th Schedule) [statutory]. - Article 82: readjustment of Lok Sabha seats after each census (frozen till first census after 2026 per 84th Amendment, 2001) — Census 2027 unlocks delimitation.

Scientific / Technological - Mobile-app based data capture; CMMS dashboards; web portal authentication via mobile OTP [S4]. - Data-security concerns: storage of PII of ~1.4 billion citizens.

Economic - Critical input for NSS surveys, NFHS, finance commission devolution, welfare targeting (PDS, PMAY, MGNREGA).
