2. Development & Social Indices

This is the largest and most-tested category, because "development" indices are exactly the ones India's own policy establishment engages with most publicly — cited in Parliament, in Economic Survey chapters, and in ministry press notes.

HDI is the anchor index of this whole category, and the one most often confused with per-capita GDP rank — HDI deliberately uses health and education alongside income precisely so that a country can rank far below its GDP-per-capita position (as India routinely does) or above it. India's "medium human development" category (as opposed to "high" or "very high") is itself a testable fact distinct from the numeric rank.

MPI is the index most likely to be paired with HDI in a "difference between" question: HDI measures national averages on three dimensions; MPI measures the same three dimensions but at the level of the individual household, counting how many separate deprivations (nutrition, child mortality, years of schooling, school attendance, cooking fuel, sanitation, drinking water, electricity, housing, assets, and bank account) a person actually experiences simultaneously — which is why India can show dramatic MPI improvement even while its HDI rank moves only slowly. Note carefully that the global MPI (UNDP/OPHI) and India's own National MPI (NITI Aayog, covered fully in Section 9) use overlapping but not identical indicator baskets and cite different headline figures — a frequent trap is quoting the National MPI's number as if it were the global MPI's, or vice versa.

Global Hunger Index is a recurring flashpoint: India's government has repeatedly rejected the GHI's methodology, arguing that its "proportion of undernourished population" sub-indicator is derived from a small opinion-poll-style survey (the Gallup World Poll's "Food Insecurity Experience Scale") rather than actual consumption data, and that this unfairly depresses India's score relative to its own National Family Health Survey data. Know that the dispute itself is a testable current-affairs fact, independent of the numeric rank in a given year.

Global Peace Index, World Happiness Report, Gender Inequality Index, and Global Slavery Index each deserve their own one-line anchor beyond the shared table row above. The Global Peace Index is built from 23 indicators grouped into three broad domains — ongoing domestic and international conflict, societal safety and security, and militarisation — and is explicitly framed by its publisher (IEP) as measuring the absence of violence ("negative peace") rather than the presence of positive social harmony, a distinction worth stating precisely if a question asks what GPI does not measure. The World Happiness Report is unusual among indices in this book for publishing its underlying explanatory regression variables (GDP per capita, social support, healthy life expectancy, freedom to make life choices, generosity, and perceptions of corruption) openly alongside the ranked life-evaluation score itself, which is why India's comparatively weaker rank is often discussed in terms of which explanatory factor is dragging the score down (commonly cited: social-support and freedom-related survey responses) rather than GDP alone — a country can be middle-income yet happier, or vice versa, precisely because of this multi-factor design. The Gender Inequality Index, nested inside UNDP's own Human Development Report rather than published as a separate flagship document, should not be confused with the WEF's standalone Global Gender Gap Report just above it in the table — GII measures reproductive health, empowerment, and labour-market participation as losses in human development due to gender inequality, while the Gender Gap Report measures relative gaps between men and women's outcomes without folding in an absolute human-development baseline; the two organisations' underlying philosophies differ (UNDP frames it as development lost, WEF frames it as parity gaps), and it is common for an MCQ to swap the two publishers as distractors. The Global Slavery Index's India figure is a favourite "absolute vs per-capita" trap in its own right, structurally identical to the "score vs rank" caution in Section 0.5 — India's enormous population alone guarantees it the largest absolute headcount of any country on almost any human-welfare-burden measure, so a careful answer always specifies whether a cited figure is an absolute count or a per-capita/prevalence rate before drawing a conclusion about India's underlying performance.

World Investment Report, UNCTAD's flagship, is easily confused with UNCTAD's other flagship, the Trade and Development Report (Section 7) — the discriminator is in the name: Investment Report tracks FDI flows and stock; Trade and Development Report tracks merchandise/services trade and broader development trends. Both come from the same Geneva-based UN body, so publisher-based elimination won't separate them — only the "investment vs trade" keyword will.

Global Wealth Report is worth anchoring to its (recently changed) publisher: Credit Suisse produced this report for two decades before its 2023 collapse and takeover by UBS, which has continued the same franchise under its own name — a good example of an index "surviving" a publisher's disappearance by being absorbed rather than discontinued, the mirror image of the Ease of Doing Business story in Section 12. Don't confuse it with the Global Wealth Report's much narrower cousin products (e.g., Knight Frank's Wealth Report, which focuses on the ultra-high-net-worth/luxury-property segment) — an examiner naming "the" Global Wealth Report almost always means the UBS one.

Practice Recall. Before reading on: in one sentence each, distinguish HDI from MPI, and name their shared parent organisation.

Answer: Both come from UNDP (MPI jointly with Oxford's OPHI). HDI = three national-average dimensions (health, education, income) combined into one composite score/rank. MPI = the same three dimensions measured as individual household deprivations, counting how many a person experiences at once, rather than a national average.
