Chart of the Day – America’s Prison Population Over the Past 100 Years

There are 2.3 million Americans in prison or jail. The U.S. has 5 percent of the world’s population but 25 percent of its prisoners. One in three black men can expect to spend time in prison. There are 2.7 million minors with an incarcerated parent. The imprisonment rate has grown by more than 400 percent since 1970. Recent research suggests that incarceration has lost its potency. A report released this week from the Brennan Center for Justice at the New York University School of Law finds that increased incarceration has had a very limited effect on crime over the past two and a half decades.
