Welcome to the Crime Reduction Toolkit

The Crime Reduction Toolkit summarises the best-available research evidence on what works to reduce crime. 

It allows users to see the impact of different interventions on crime and understand how they work, where they work, how to implement them and their cost.  The Toolkit can be viewed in table mode and bubble mode; both of which draw on the same research evidence.
