What is the most unequal country in South America? It depends on what metric you look at. One way to measure income inequality is to look at the share of all income that goes to the top income earners.

At the turn of the millennium, 2.2 billion people in the world lived in extreme poverty. In international statistics, this means they survived on less than $3 per day (in todayâs money). In the two decades that followed, this number more than halved. You can see this decline in the chart.
