    Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure) among individuals or households within an economy deviates from a perfectly equal distribution. A Lorenz curve plots the cumulative percentages of total income received against the cumulative number of recipients, starting with the poorest individual or household. The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line. Thus a Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality. Source: World Bank, Poverty and Inequality Platform. Data are based on primary household survey data obtained from government statistical agencies and World Bank country departments. Data for high-income economies are mostly from the Luxembourg Income Study database.

    Open at source

Series-level selection: for each country the whole series comes from the highest-priority source that has any non-forecast value for it. If a lower-priority source is more than three years fresher, the freshest source wins instead. Non-chosen values are kept as alternatives, never discarded.

Countries without data

Typical reasons: the source does not survey small territories or micro-states; the statistical office reports with a lag of one to three years; the series is only compiled for member countries of the source organisation (OECD, EU, Eurostat); or a value exists but failed validation and is quarantined rather than shown.
