Male prisoners are exposed and subject to sexual and physical violence in prisons. When these events occur, the victim usually suffers emotionally and/or physically. Studies suggest that this leads the inmate to accept these types of behaviors and value their lives and the lives of others less when they are released. These dehumanizing acts, combined with learned violent behavior, are implicated in higher recidivism rates. Two studies were done to attempt to provide a “national” recidivism rate for the US. One was done in 1983 which included 108,580 state prisoners from 11 different states. The other study was done in 1994 on 272,111 prisoners from 15 states. Both studies represent two-thirds of the overall prisoners released in their corresponding years. An image developed by Matt Kelley indicates the percent of parolees returning to prison in each state in 2006. According to this image, in 2006, there was more recidivism in the southern states, particularly in the Midwestern region. However, for the majority, the data is spread out throughout the regions.
