HDI is a composite metric (life expectancy, schooling, GNI per capita) released annually by UNDP; India's overall HDI rose from 0.590 (2010) → 0.633 (2015) → 0.685 (2023) per HDR 2025 [1].
No official ST-disaggregated HDI is published in India, making MPCE (HCES 2023-24) the de facto proxy for measuring tribal welfare [1][2].
Relevant for GS-I (society/tribes) and GS-II (vulnerable sections, welfare schemes).
2. Why in the News
Lok Sabha Question (12 March 2026): MoS Tribal Affairs Shri Durgadas Uikey stated that UNDP HDI is computed only nationally and that ST-disaggregated HDI data is not published in India [1].
3. Background & Evolution
HDI introduced by UNDP in 1990 (Mahbub ul Haq, Amartya Sen); India's first National Human Development Report published by Planning Commission in 2001.
Ministry of Tribal Affairs (MoTA) created in 1999 (bifurcated from Ministry of Social Justice & Empowerment).
HCES (NSO) restored in 2022-23 after a gap since 2011-12; provides social-group break-ups including ST [2].
4. Core Static Facts
Implementing/Nodal: Ministry of Tribal Affairs (Union); HDI computed by UNDP (HDRO), not by GoI [1].
HDI components (per PIB): (i) Life expectancy at birth; (ii) Expected/Mean years of schooling; (iii) GNI per capita[1].
GS-I: Social empowerment; issues of tribal communities.
GS-II: Welfare schemes for vulnerable sections; mechanisms for protection of STs.
GS-III: Inclusive growth and development indicators.
Question stems:
1. "In the absence of disaggregated HDI for Scheduled Tribes, how can India robustly measure tribal welfare? Discuss."
2. "Evaluate PM-JANMAN as a saturation-based intervention for PVTGs."
3. "Compare HDI and MPCE as instruments for assessing tribal development outcomes."

10. Common Errors / Trap Areas
HDI is released by UNDP, not World Bank/UNESCO/NITI Aayog.
HDI uses GNI per capita (PPP $), not GDP per capita.
ST-HDI is not officially published — do not quote any figure as "ST HDI".
PM-JANMAN is for PVTGs specifically, not all STs (vs. PMAAGY which covers ST-majority villages).
HCES is by MoSPI/NSO, not Ministry of Tribal Affairs.
