Gini Index

Gini index (0 = perfect equality, 100 = perfect inequality)·Higher is worse — rank 1 is worst affected·Published by World Bank Group

We hold 21 editions of this indicator, from 2002 to 2022 — 1,677 rows in total, and 73 countries in the newest.

21 reference years (2002–2022), covering 60 to 93 countries, from the World Bank’s own Poverty and Inequality Platform via its indicator API (SI.POV.GINI). The Gini index measures how far a country’s income distribution departs from perfect equality. ⚠ THE COUNTRY SET CHANGES EVERY YEAR, and this is the thing to understand before reading any trend: each figure comes from whichever household survey that country happened to run, so a country missing from an edition did not become equal - it did not run a survey. A single country’s line over time is meaningful; comparing the spread of one year against another is not, because the two years describe different groups of countries. ⚠ Years outside 2002–2022 are not imported because they fall below 60 countries - 2023 has 57, 2024 has 25 and 2025 has 4 so far, and the pre-2002 years are thinner still. ⚠ The Bank publishes no rank, so none is stored; the POSITION shown on the statistics page is derived here by ordering the score, and is labelled as ours. Opted in 2026-09-10, once PIP’s full precision made the ordering clean: no more than TWO countries share a value in any of the 21 editions (2.7% of the field at its worst), where the Bank’s one-decimal copy tied three and collapsed 73 economies onto 59 distinct values. Read from the Bank’s Poverty and Inequality Platform (PIP), not its indicator API: the API re-publishes PIP rounded to one decimal, so Slovakia’s 24.08 arrived as 24.1. Re-sourced 2026-09-09. ⚠ Nineteen countries ran an income AND a consumption survey in the same year; only one can be an edition row, and the two differ by up to 8 index points. The choice is not made here — it is read out of the Bank’s own published figure for that country-year (income in 83 cases, consumption in 5).
