From the mid-1970s to the mid-’80s, America’s incarceration rate doubled, from about 150 people per 100,000 to about 300 per 100,000. From the mid-’80s to the mid-’90s, it doubled again. By 2007, it had reached a historic high of 767 people per 100,000, before registering a modest decline to 707 people per 100,000 in 2012. In absolute terms, America’s prison and jail population from 1970 until today has increased sevenfold, from some 300,000 people to 2.2 million. The United States now accounts for less than 5 percent of the world’s inhabitants—and about 25 percent of its incarcerated inhabitants. In 2000, one in 10 black males between the ages of 20 and 40 was incarcerated—10 times the rate of their white peers. In 2010, a third of all black male high-school dropouts between the ages of 20 and 39 were imprisoned, compared with only 13 percent of their white peers.
