For the first time, BJS used prison records from the National Corrections Reporting Program and criminal history data to analyze various characteristics and the arrest history of persons admitted to state prison in the United States. The report presents findings on the age at first arrest, number of prior arrests, and length of criminal history of persons admitted to state prison in 2009 and 2014. It also examines the post-prison arrests during the 2 years following their release from prison.
- More than 1 in 4 persons admitted to state prison in 34 states in 2014 had been sentenced for a violent offense.
- The 369,200 persons admitted to state prison in 34 states in 2014 had an estimated 4.2 million prior arrests in their criminal histories, including the arrest that resulted in their prison sentence.
- In both 2009 and 2014, persons admitted to prison had a median of nine prior arrests in their criminal histories.
- About 1 in 10 persons admitted in 2014 at age 24 or younger had at least one prior out-of-state arrest, and about 4 in 10 persons admitted at age 40 or older had at least one such arrest.
