If you feel like the gap between the world’s rich and poor is widening, you may be right.Since the 1980s, countries like New Zealand, Israel, and the United States have seen their populations become less equal, based upon rapid income growth for those countries richest. Others like Turkey and Chile have become more equal as a result rapid development.

Inequality is measured using the Gini coefficient, which is imperfect, but a good indicator of inequality within countries. The larger the Gini coefficient, the more unequal a country is.

Note: Measured using the Gini coefficient, the OECD average is 0.31. We’ve listed all those countries which are equal to, or above that average, according to OECD data. The list is limited to OECD countries.
