Many ex-prisoners reoffend.
Almost a third (31%) of people released from prison in 2016 were again convicted of an offense committed the year after their release, according to a study published Thursday in the statistical newsletter of the justice system.
"The risk of recidivism is all the higher as people are young when they enter prison, and increases with the number of previous convictions", write the statisticians Frédérique Cornuau and Marianne Juillard in the July issue of the bulletin " Justice infostat ”, produced by the Chancellery.
The study carried out by the statistical service of the Ministry of Justice (SDSE) concerns 41,500 convicted and imprisoned adults who left penitentiary establishments in mainland France and overseas in 2016.
Often young repeat offenders
According to the data collected, half of these detainees were under 30 years old before entering detention, nearly two-thirds had a low level of education and 86% of them had already been convicted in the past.
Two out of five prisoners in 2016 also spent less than six months in jail, short sentences that were often desocializing and rarely amended, the modification of the sentence being a means of combating recidivism.

Among the entire population studied, 5% reoffended within 30 days of release from prison and 20% within six months.
79% of repeat offenders were sentenced to a new prison sentence.
The recidivism rate varies greatly depending on the initial offense, with perpetrators of simple thefts (43%) or aggravated thefts without violence (39%) being the most likely to be re-convicted, while perpetrators of sexual violence reoffend few in the short term (12%) just like the perpetrators of homicide (9%).
Recidivism probably underestimated
The offenses subject to a long judicial treatment may however not have been taken into account and "an underestimation of recidivism is therefore probable", warn the statisticians.
For the authors of the study, the other factors influencing recidivism are sex and age, men being twice as concerned as women and 55% of 18-20 year olds compared to 12% of 60 year olds and over.
People with a heavy judicial past and with psychological and psychiatric disorders also reoffend more.
Finally, "the fact of working in prison slightly reduces the risk of committing a new offense, by 1.8 points," says the study.
