INCOME INEQUALITY BETWEEN THE 1% AND THE 99%
Data on the top 1%’s share of income are available for nineteen rich democracies. They are compiled by the World Top Income Database, using tax records. These data are for pretax income excluding capital gains.
INCOME INEQUALITY WITHIN THE BOTTOM 99%
The following charts show the Gini coefficient for household income in the lower 99%. The Gini can range from zero to 100, with larger numbers indicating greater inequality. The incomes include government transfers and subtract taxes. The data are from three sources: the Luxembourg Income Study (LIS), the OECD, and Frederick Solt’s Standardized World Income Inequality Database.
INCOME INEQUALITY IN THE LOWER HALF
The following charts show the ratio of household income at the 50th percentile (median) to income at the 10th percentile. This is a useful indicator of inequality within the lower half of the income ladder. The incomes include government transfers and subtract taxes. For most countries we have two data sources: the Luxembourg Income Study (LIS) and the OECD.
