Position

The bubbles in the top section of the chart are the most effective in reducing crime. The positioning is determined by analysis of the best-available evidence. Only interventions that have been subject to a systematic review of the evidence are included in the Toolkit

Colour

​The bubbles are colour-coded based on the context in which the interventions are implemented.  They can be filtered by prevention, diversion or reoffending and any combination of these

Size

​The larger the bubble, the better the quality of the evidence about the intervention.  Quality is based on a range of methodological issues and ratings are based on the method used to review the research, not the methods of single research studies

Filters

​These can be used to find the most relevant interventions. Filters are arranged in 4 sections:
focus:  the context the intervention is usually delivered in
problem:  crime type or issue. This is based on what crime type is used to measure the effectiveness of the intervention
population:  age of perpetrator. You can also select location to find place-based interventions
factor:  characteristics of the intervention e.g. policies related to alcohol sales, or the problem e.g. gang-related crime

Clicking filters in each section can help focus your search and clicking multiple filters in the same section expands your search. These filters can be cleared using the reset filters button

Pins

​Each bubble has a pin to allow you to keep the bubble expanded, showing a brief description of the intervention. Multiple pins can be applied at a time so you can use the pins to view what options there are to tackle particular crime problems. Click or tap the pin to minimise the bubble again  

Sharing

​The sharing functions at the top right of the screen allow you to show the results of your filtered search to others. You can share by e-mail or on social media

Evidence summaries

​Click ‘read more’ on a bubble to read a short summary of the findings of the research. The summaries are based on the EMMIE framework developed by UCL
