Gini Coefficients
Gini coefficients for the majority of countries in the Equity Calculator database are taken from the World Income Inequality Database.[17] For countries which have reliable national or supranational sources (e.g., US Census Bureau, EU Europa database) newer Ginis are used where available. For some countries other sources are used, and for those for which no published figures are available, Gini coefficients are estimated on the basis of comparable countries.
