The most unequal countries in the world include third world nations, emerging markets and one global superpower.America is the #39 most unequal country in the world, based on the CIA-recognised Gini index.

The U.S. has more income inequality than Russia (#51) and China (#52). It ranks far worse than Portugal (#71), which is the worst in Western Europe.

The Gini index is calculated based on the range of cumulative family incomes, where 0 stands for perfect equality and 100 stands for perfect inequality.

Gini coefficient measures inequality, with 0 expressing total equality and 100 maximal inequality.
