The report said prison growth and higher incarceration rates do not reflect a parallel increase in crime or in the nation’s overall population. Instead, it said, more people are behind bars mainly because of tough sentencing measures, such as “three-strikes” laws, that result in longer prison stays.
“For some groups, the incarceration numbers are especially startling,” the report said. “While one in 30 men between the ages of 20 and 34 is behind bars, for black males in that age group the figure is one in nine.”
The nationwide figures, as of Jan. 1, include 1,596,127 people in state and federal prisons and 723,131 in local jails — a total 2,319,258 out of almost 230 million American adults.
The report said the United States is the world’s incarceration leader, far ahead of more populous China with 1.5 million people behind bars. It said the U.S. also is the leader in inmates per capita (750 per 100,000 people), ahead of Russia (628 per 100,000) and other former Soviet bloc nations which make up the rest of the Top 10.
