Indices India Is Ranked On: HDI, GII, GHI, EPI — What Each One Measures

1. Who Publishes What — The Agency Mix-Up

HDI (Human Development Index) - Published by the UNDP (United Nations Development Programme) inside its annual Human Development Report; introduced in 1990 by economist Mahbub ul Haq.
Mnemonic Hook: "HDI is the UN's report card on living a long, educated, well-off life."
Link: Pair with the fact that the 2025 report uses 2023 data - UNDP's rankings always lag the current year by about two years.

GII (Gender Inequality Index) - Also published by UNDP, inside the same Human Development Report, alongside the HDI; introduced in the 2010 HDR to replace the older Gender Development Index (GDI) and Gender Empowerment Measure (GEM) of 1995.
Mnemonic Hook: "GII is HDI's sibling index - same parent (UNDP), same report, different question (how equal, not how developed)."
Link: Link to GDI/GEM (1995) as the "failed older version" GII was built to fix.

GHI (Global Hunger Index) - Published jointly by two NGOs: Concern Worldwide (Ireland) and Welthungerhilfe (Germany); first released in 2006, originally with IFPRI (International Food Policy Research Institute) as a partner.
Mnemonic Hook: "GHI comes from two European charities, not the UN - 'Concern' and 'Welt' (world) hunger."
Link: Released every October, timed near World Food Day (16 October).

EPI (Environmental Performance Index) - Published by Yale and Columbia Universities (Yale Center for Environmental Law & Policy and Columbia's CIESIN), originally launched with the World Economic Forum in 2002.
Mnemonic Hook: "EPI is the Ivy League's report card on the environment - Yale and Columbia, not the UN."
Link: Released every two years (biennial) - most recently in 2024, next due 2026.

2. Higher Is Better or Lower Is Better — The Direction Trap

HDI - higher is better - Scale of 0 to 1; closer to 1 means greater human development.
Mnemonic Hook: "HDI climbs like a ladder - the higher you are, the better off you are."
Link: Same direction logic as EPI below - both are "achievement" scores.

GII - lower is better - Scale of 0 to 1; 0 means perfect gender equality, 1 means total inequality.
Mnemonic Hook: "GII is a problem score, not a progress score - zero problems is the goal."
Link: Link to GHI below - both GII and GHI are "severity" scores where you want to sink toward zero.

GHI - lower is better - Scale of 0 to 100; 0 is the best possible (no hunger), 100 the worst.
Mnemonic Hook: "GHI measures hunger, and nobody wants a high hunger score."
Link: Shares its "lower is better" logic with GII, not with HDI/EPI.

EPI - higher is better - Scale of 0 to 100; 100 is the best environmental performance.
Mnemonic Hook: "EPI behaves like an exam score out of 100 - score high, perform well."
Link: Easy to confuse with GHI since both run 0-100, but EPI climbs toward 100 while GHI sinks toward 0.

3. Human Development Index (HDI) — The Three-Dimension Classic

What it measures - Three dimensions: a long and healthy life (life expectancy at birth), knowledge (mean years of schooling + expected years of schooling), and a decent standard of living (GNI per capita, PPP $).
Mnemonic Hook: "HDI = Health + Education + Income - the three pillars every civics textbook repeats."
Link: Connect to the four underlying indicators - two of the three dimensions (education) need two indicators each, so HDI math uses four data points for three dimensions.

India's latest standing - HDR 2025 (using 2023 data): HDI value 0.685, rank 130th of 193 countries, category "Medium Human Development" - just short of the 0.700 "High" threshold.
Mnemonic Hook: "India is at 130 out of 193 - remember it as '130 steps still to climb to High.'"
Link: Link to the four HDI categories: Low (below 0.550), Medium (0.550-0.699), High (0.700-0.799), Very High (0.800 and above).

4. Gender Inequality Index (GII) — The Three Dimensions of Gender Gaps

What it measures - Three dimensions: reproductive health (maternal mortality ratio + adolescent birth rate), empowerment (female parliamentary seat share + secondary-or-higher education attainment), and labour market participation (female labour force participation rate).
Mnemonic Hook: "GII's three dimensions spell R-E-L: Reproductive health, Empowerment, Labour market."
Link: Link reproductive health's "maternal mortality ratio" to the same MMR used in India's SDG and National Health Policy targets - it is a recurring static-GS figure.

India's latest published standing - Rank 108th of 193 countries with a GII value of 0.437 (2022 data, released in HDR 2023-24) - the most recent GII figure UNDP has published for India at the time of writing.
Mnemonic Hook: "GII's '108' is easy to swap with HDI's '130' - remember GII's number is always smaller because fewer countries get a complete-enough gender dataset in some editions."
Link: Link to the fact that GII is published inside the same HDR as HDI but is not always updated in lock-step every single year.

5. Global Hunger Index (GHI) — The Four Hunger Indicators

What it measures - Four component indicators: undernourishment (insufficient caloric intake), child stunting (low height-for-age), child wasting (low weight-for-height), and child mortality (under-five death rate).
Mnemonic Hook: "GHI's four indicators spell U-S-W-M: Undernourishment, Stunting, Wasting, Mortality - two are about calories/death, two are about child growth."
Link: Link stunting (chronic, long-term) versus wasting (acute, short-term) - UPSC loves to swap these two definitions.

India's 2025 standing - Score 25.8, rank 102nd of 123 countries, severity category "Serious" (the band runs from 20.0-34.9); components were undernourishment 12.0%, child stunting 32.9%, child wasting 18.7%, child mortality 2.8%.
Mnemonic Hook: "GHI's severity ladder climbs: Low, Moderate, Serious, Alarming, Extremely Alarming - India sits on rung three, 'Serious.'"
Link: Link India's persistently high child wasting rate (among the world's highest) to the government's repeated objections to GHI's methodology.

6. Environmental Performance Index (EPI) — The Three Policy Objectives

What it measures - 58 indicators grouped into 11 issue categories under three broad policy objectives: Climate Change (emissions and projected emissions), Environmental Health (air quality, sanitation, drinking water, heavy metals, waste management), and Ecosystem Vitality (biodiversity, forests, fisheries, agriculture, air pollution, water resources).
Mnemonic Hook: "EPI's three objectives spell C-H-V: Climate, Health, Vitality (of ecosystems)."
Link: Link "Environmental Health" here to "public health," not to ecosystem health - a common mix-up with the Ecosystem Vitality objective.

India's 2024 standing - Overall rank 176th of 180 countries, score 27.6; worst on Environmental Health (177th, score 13.5), followed by Ecosystem Vitality (171st, score 30.4) and relatively better on Climate Change (133rd, score 35.0).
Mnemonic Hook: "India's weakest EPI leg is Health, not Climate - air and water quality drag the overall score down the most."
Link: Link to the Indian government's standard rebuttal - that EPI undervalues India's per-capita low emissions and forest-cover gains.

Quick Revision List

• Agency map: HDI and GII - UNDP; GHI - Concern Worldwide & Welthungerhilfe; EPI - Yale & Columbia Universities.

• Direction map: HDI and EPI - higher is better; GII and GHI - lower is better.

• India's current snapshot: HDI rank 130/193 (Medium); GII rank 108/193; GHI rank 102/123 (Serious); EPI rank 176/180.

• Scale map: HDI and GII run 0-1; GHI and EPI run 0-100 - but a 0-100 scale does not mean the same direction (GHI sinks to 0, EPI climbs to 100).

• GII was built to replace GDI/GEM (1995) and was introduced in the HDR's 20th-anniversary edition (2010).

• EPI is the only one of the four not released every year - it is biennial.

Common Confusion Traps

• Assuming all four indices are published by the UN/UNDP: Only HDI and GII come from UNDP; GHI comes from two European NGOs and EPI from Yale and Columbia Universities.

• Assuming a higher score is always better: True for HDI and EPI, but false for GII and GHI, where a lower score signals better performance.

• Confusing GII's rank with HDI's rank for India: HDI rank (130/193) and GII rank (108/193) measure entirely different things - swapping them is a classic Prelims trap.

• Mixing up child stunting and child wasting in GHI: Stunting is chronic (low height-for-age, long-term undernutrition); wasting is acute (low weight-for-height, short-term/sudden undernutrition).

• Treating EPI's "Environmental Health" as ecosystem health: It actually covers human health risks from air quality, sanitation, drinking water and waste - "Ecosystem Vitality" is the separate objective for biodiversity and forests.

• Assuming EPI is released annually like GHI: EPI is biennial (every two years); only GHI and the HDR (hosting HDI/GII) are annual.
