More than half (57 percent) of violent offenders who were released from state prison in 2016 served less than three years before their release, the Bureau of Justice Statistics announced today. About 1 in 25 violent offenders served 20 years or more before their release.
These findings are based on prisoner records from BJS’s National Corrections Reporting Program and reflect 2016 releases. They are based on state prisoners’ initial release after serving time for a given offense and exclude persons who had been released after serving time for an offense, returned to prison for violating community supervision and were released again.
The average time an offender served in state prison in 2016, from the date of first admission to initial release, was 2.6 years. The median amount of time served (the middle value in the range of time served, with 50 percent of offenders serving more and 50 percent serving less) was 1.3 years. Persons serving less than one year in state prison made up 40 percent of first releases in 2016.
Based on 2016 release data, the average time served before initial release by state prisoners who were sentenced for a violent offense was 4.7 years and the median time was 2.4 years. Offenders sentenced for murder or non-negligent manslaughter served an average of 15 years and a median time of 13 years in state prison before initial release. State prisoners sentenced for rape or sexual assault served an average of 6.2 years and a median time of 4.2 years before initial release.
An estimated 96 percent of violent offenders released in 2016, including 70 percent of those sentenced for murder or non-negligent manslaughter, served less than 20 years before initial release. Roughly 1 in 5 persons released in 2016 after being sentenced for rape or sexual assault served 10 or more years before initial release.
State prisoners serving time for drug offenses, including trafficking and possession, served an average of 22 months and a median time of 14 months before their initial release. About 3 in 5 offenders released after serving time for drug possession served less than one year before their initial release.
In general, state prisoners served an average of 46 percent of their maximum sentence before their first release. Violent offenders served 54 percent of their maximum sentence, property offenders served 42 percent, drug offenders served 41 percent and public order offenders served 45 percent.
Persons in state prison for rape or sexual assault served an average of 62 percent of their maximum sentence before initial release. Those in prison for drug possession served an average of 38 percent of their maximum sentence length.
