The Pew Center on the States has just released a new report that finds that one out of 100 adult Americans is in prison–the highest rate in the world. According to the Pew Center press release:
…at the start of 2008, 2,319,258 adults were held in American prisons or jails, or one in every 99.1 men and women, according to the study. During 2007, the prison population rose by more than 25,000 inmates. In addition to detailing state and regional prison growth rates, Pew's report, One in 100: Behind Bars in America 2008, identifies how corrections spending compares to other state investments, why it has increased, and what some states are doing to limit growth in both prison populations and costs while maintaining public safety.
As prison populations expand, costs to states are on the rise. Last year alone, states spent more than $49 billion on corrections, up from $11 billion 20 years before. However, the national recidivism rate remains virtually unchanged, with about half of released inmates returning to jail or prison within three years. And while violent criminals and other serious offenders account for some of the growth, many inmates are low-level offenders or people who have violated the terms of their probation or parole.
On the other hand, Department of Justice data show that as our prisons filled, crime rates plummeted.
