Justice Data Lab Re-Offending Analysis: HMP Downview D Wing Resettlement Unit

This document describes an evaluation of the effectiveness of the D Wing Resettlement Unit at HMP Downview on reducing re-offending rates among offenders. The study analyzed data from 109 offenders between 2002 and 2010, with 70 successfully matched to the Police National Computer. A control group of 33 offenders was also established for comparison. The evaluation utilized statistical testing and confidence intervals to assess re-offending rates, which showed no statistically significant difference between the treatment and control groups, with both exhibiting a 15% re-offending rate. The study highlights the importance of considering confidence intervals and acknowledges limitations such as potential selection bias, missing information, and the need for a larger sample size. It also notes the exclusion of sex offenders due to distinct re-offending patterns and provides a standardized difference key to compare offender characteristics between groups.
