Abstract

Employment is essential for reducing recidivism. Accurately reporting employability post-release from prison figures is important for understanding real trends in data. This paper examines the impact of statistical reporting methods on the interpretation of employment data for individuals released from prison. By analysing the Ministry of Justice’s (MoJ) reporting practices, we highlight how the use of percentage-of-percentages can distort the true picture of employment outcomes. We argue that such methods exaggerate small changes and obscure real trends, leading to potential misallocation of resources and misguided policy decisions. We recommend a shift towards reporting raw values, percentage points, and enhanced visualisation of the data to provide a clearer, more accurate representation of employment. This approach will enhance transparency and support more effective policymaking aimed at reducing recidivism through improved employment opportunities for people post-release.
