Annual 1990–2024 · World Bank PIP via Our World in Data · coefficient 0–1
Gini coefficient — income or consumption inequality — on a scale from 0 (perfect equality) to 1 (maximum inequality). Annual series, 1990-2024.
World Bank, Poverty and Inequality Platform (PIP 2026), via Our World in Data. Gini is measured through irregular surveys: any single year is covered by only 55 to 93 countries. To maximise displayed coverage, the last known survey value is carried forward to later years (a display carry-forward, not a new measurement); a country never measured stays grey, with no backward fill.
Time slider. Depending on the country and year, the underlying base is income (after taxes and transfers) or consumption — hence levels sometimes lower than the more widely reported "income" Gini figures.
Brazil (0.539) and Colombia (0.516) rank among the most unequal societies in the world, a legacy of colonial-era land and social structures that has barely shifted despite decades of redistributive policy. At the other end, Slovenia (0.246) and Czechia (0.25) show among the lowest inequality — a legacy shared by most former Eastern Bloc countries, where income flattening remains a lasting trace of the communist era.
