The Cardiff Model
for Violence Prevention National Network
The Cardiff Model for Violence Prevention
More than half of violent crimes in the U.S. are not reported to law enforcement. That means cities and
communities may not fully understand where and how frequently violence occurs, which limits their ability
to develop effective solutions.
Initially developed and implemented in Cardiff, Wales, the Cardiff Model for Violence Prevention is a multi-agency, public health approach to violence prevention. The Model combines and maps violent injury data from hospitals, emergency medical services, and law enforcement to assist people and agencies in preventing violence in their communities. This method of sharing and mapping data helps communities more effectively identify where violence frequently occurs. More than just an approach to map violence, the Cardiff Model also provides a straightforward framework for sustained partnership between hospitals, law enforcements agencies, public health agencies, community groups, and others to develop, deliver, and monitor collaborative, place-based violence prevention strategies. In Cardiff, Wales, the Cardiff Model has proven effective in reducing hospital admissions for violent injuries.
