5. Multi-Dimensional Analysis

Administrative / Governance - Conducted in rolling state-wise windows rather than one synchronised national month, to ease logistics across 28 States + 8 UTs. [S2] - Hybrid model: SE (digital, self-driven) followed by enumerator door-to-door to ensure coverage of non-digital households. [S1]

Scientific / Technological - First digital census of India: paperless data capture via mobile app, real-time encrypted upload, faster processing. [S5][S1] - Self-Enumeration generates a unique SE ID linking online submission to field verification — reduces duplication. [S1]

Legal / Constitutional - Census is a Union subject — Entry 69, List I, Seventh Schedule. [S5] - Confidentiality guaranteed under Sec 15, Census Act 1948; participation is statutorily compulsory. [S7]

Social - Caste enumeration in Phase II — first comprehensive caste count since 1931 (SECC 2011 caste data was never released). [S6] - Data feeds delimitation, women's reservation operationalisation, and welfare targeting. [S5]

Economic - Houselisting data underpins MPI poverty estimates, PMAY, Jal Jeevan Mission, Swachh Bharat baselines (assets, drinking water, sanitation, fuel). [S7] - Foundation for NSO sampling frames, GDP rebasing post-2026. [S5]
