Countries
The World Bank publishes a 2021 Gini index for 79 of the 176 countries on this map. A Gini index needs a household income or consumption survey, so a blank country is one with no such survey published for 2021.

Classification
Palette
A diverging palette needs a real centre, and only fertility has one here, so brown–teal is offered there alone. Red–blue is kept for two-party vote share.
Projection
Italic labels mark measures with a value for fewer than 70% of the 176 countries drawn.
Income inequality (Gini index), 2021
79 of 176 countries have a value
Reading this map: A Gini index needs a household income or consumption survey. The blank countries are mostly those that ran no such survey for 2021 or did not publish one, so the gaps are not spread at random.

Coverage is part of the map
The 11 measures here range from 170 countries with a value to 79. A value is usually missing because a country did not run or publish the survey behind it, and the countries without household income surveys are not a random sample. The blank areas on the 2021 inequality map show who measured inequality that year.
Switching inequality to each country’s latest survey fills the map for 154 countries, with survey years from 1992 to 2025, and 43 of those surveys predate 2020.
The classification control changes which countries share a colour while the values stay the same. Countries are the only level here, because every series on this page is published for whole countries.
Borders and disputed territories
The outlines are Natural Earth’s 1:110m countries (version 5.1.2), which draws borders by who controls the ground rather than by claims. Western Sahara is drawn in two parts, with the part Morocco administers inside Morocco’s outline and the rest as a separate polygon. Kosovo, Palestine (the West Bank; Gaza is too small to draw at this scale), Taiwan, Northern Cyprus and Somaliland are separate polygons. Crimea is inside Russia’s outline, and Kashmir is divided among India, Pakistan and China by the area each administers.
South Sudan, Kosovo and Palestine take their values from the World Bank codes SSD, XKX and PSE. Western Sahara, Northern Cyprus and Somaliland have no value on any of the 12 maps here; Taiwan has a value on 2 of them, Kosovo on 8 and Palestine on 8.
