A new Justice Department study has found that some 5.6 million people living in the U.S. have been incarcerated at one time. Over the last 30 years the number of current and former inmates has risen by 3.8 million.

About 17 percent, or nearly one in five, African-American male adults have been or are in prison. That’s compared to nearly 8 percent of Latino men and about 2 and a half percent of white men.

The study went on to determine that if the incarceration rate from 2001 stays steady, one in three African-American men born in the year 2001 will serve time in jail at some point in their lives.
