OECD Countries: All 38 Members

About these figures

• Combined figures are sums of the members’ own figures for one year, not official aggregates, and are shown only when every member has a figure for that year. Missing figures are not counted as zero.
• Growth, inflation and other rates are not added up or averaged into a group or continent rate, because an unweighted average gives a small economy the same weight as a large one.
• GDP is converted to US dollars at market exchange rates; GDP at purchasing power parity (PPP) adjusts for differences in price levels, so it is the better comparison of living standards and gives a different order.
• The tax column is central government tax revenue as the World Bank publishes it. It is not the OECD’s own tax-to-GDP ratio, which also counts social security contributions and taxes raised by state and local government, so it is lower, sometimes much lower, in federal countries. The Gini index comes from household surveys run in different years, shown in each cell.
• IMF figures for the current year are projections from the World Economic Outlook, revised at each release, not measured values.

Gini index SI.POV.GINI

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. Unit: 0 (equal) to 100. World Bank (World Development Indicators)

Central government tax revenue GC.TAX.TOTL.GD.ZS

Taxes are compulsory, unrequited payments, in cash or in kind, made by institutional units to government units. This indicator is expressed as a percentage of Gross Domestic Product (GDP) which is the total income earned through the production of goods and services in an economic territory during an accounting period. Unit: % of GDP (World Bank). World Bank (World Development Indicators)
