economic inequality

economic inequalities (ref:Wikipedia)

Differences in national income equality around the world as measured by the national Gini coefficient. The Gini coefficient is a number between 0 and 1, where 0 corresponds with perfect equality (where everyone has the same income) and 1 corresponds with perfect inequality (where one person has all the income, and everyone else has zero income). Countries in red tones have societies with more income inequality than those in green tones.

Note that Iran and the US have the same economic inequality and Greenland, Denmark, Hungary and Japan are the fairest countries!
