This World Map Shows The Enormity Of America's Prison Problem
About 2.4 million people live behind bars in America — the highest number in the world. That's a little more than 0.7% of the population and more than 700 for every 100,000 people. This world map illustrates how disconcerting that is. The size of each country corresponds to the size of its total prison population (as of 2010), and a darker color indicates a higher incarceration rate.
