Time Served: The High Cost, Low Return of Longer Prison Terms

The length of time served in prison has increased markedly over the last two decades, according to a new study by Pew's Public Safety Performance Project. Prisoners released in 2009 served an average of nine additional months in custody, or 36 percent longer, than offenders released in 1990.

Over the past 40 years, criminal justice policy in the U.S. was shaped by the belief that the best way to protect the public was to put more people in prison. Offenders, the reasoning went, should spend longer and longer time behind bars.
