With a record-setting 2 million people locked up in American jails and prisons, the United States has overtaken Russia and has a higher percentage of its citizens behind bars than any other country.
...During the 1990s, the United States and Russia vied for the dubious position of the highest incarceration rate on the planet.
But in the past few years, Russian authorities have carried out large-scale amnesties to ease crowding in disease-infested prisons, and the United States has emerged unchallenged into first place, at 702 prisoners per 100,000 population. Russia has 665 prisoners per 100,000.
Today the United States imprisons at a far greater rate not only than other developed Western nations do, but also than impoverished and authoritarian countries do.
On a per capita basis, according to the best available figures, the United States has three times more prisoners than Iran, four times more than Poland, five times more than Tanzania and seven times more than Germany. Maryland has more citizens in prison and jail (an estimated 35,200) than all of Canada (31,600), though Canada's population is six times greater.
