The United States has the highest incarceration rate in the world, higher than that of Russia and China, with a rate of 655 per 100,000. The United States imprisons more people, 2.2 million, than any other nation. The incarceration rate in America is so high that the line representing the United States extends well off the page in graphics of the prison rates in the developed world. If the U.S. prison population were a city, it would be the fifth largest in America.
