As part of the Home Office’s Ending Gang and Youth Violence programme a commitment was made to help police forces better understand their local gang issues (HM Government, 20131 ). This research aims to meet this commitment by testing the use of social network analysis using police intelligence data, as a tool to more systematically understand gangs and to help direct law enforcement activities. As such, the report serves as one example of how social network analysis can be used, but the approach could also be applied to other types of crime and disorder to explore the networks of people involved (such as those connected to acquisitive crime or sexual abuse). The research was undertaken in partnership with Great Manchester Police and addresses two research questions: 1. What can social network analysis tell us about gangs? 2. How useful are the social network analysis outputs for the police? For this, five individuals living in Manchester and identified as having gang links were chosen as the starting point for the network analysis. Further details about how to conduct social network analysis can be found in the ‘How to guide’ 2 published as an annex to this report.
