We hope you will find here something that is of interest and we will add new material as that is developed. In particular we explore a range of policy examples which we intend to be a growing repository of quantitatively analysed criminal justice ideas. The scope and accuracy of the simulation engine continue to be developedand tested. The algorithms are periodically reviewed for improvement and so the results may change or be updated. So come back often to see what is new, but please read the disclaimer.
If you have a project where you think we can help, want to ask questions and give feedback or wish to support this work, please get in touch.
Tackling crime, punishing and rehabilitating offenders, remain core issues to the wellbeing and proper governance of any country. In general, justice systems comprise many agencies working together - the police, prosecution, courts, prisons, probation, health and other social support organisations. The processes involved are multistage with decisions taken by different agencies and at different times. The impacts of sentencing and effects of interventions can take time to work through. All this poses some tough challenges for policy makers and organisational leaders in how best to analyse the available data, to identify underlying principles and draw meaningful and robust conclusions, better to reform such services and to improve outcomes.
We use scientific, quantitative methods to explore policy and practice issues in criminal justice and related areas. We emphasise whole system approaches using simulation, among other techniques, to help understand the operation of justice systems and to explore the impact of policy and practice reforms. While predominantly the results shared here are for England & Wales, the techniques and methods involved are general and could be applied to other judicial settings.
