In states across the country, private prisons have been plagued with a multitude of problems – major riots have exploded, inmates have died, and civil rights have been routinely violated. Private prisons have an economic motive to cut costs in every area of operations, resulting in lower quality staff, higher employee turnover, and degrading prison conditions. These dismal conditions directly contribute to the decreased security and higher incidence of violence found at privatized prisons.

In this backgrounder brief, we discuss findings from research in this area, share experiences of states that have privatized prisons, and profile a few of the major for-profit private prison operator.
