About this ranking

Income inequality on a 0 to 100 scale, where 0 is perfect equality.

Covers Spain, the EU and its countries, and the United States. For other countries use gini_index_world_bank, which is measured on a different basis. US values measure household money income before taxes and are not directly comparable with the EU-SILC measure based on equivalised disposable income.

Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. Equal values share a rank.
