Wales cuts reported violence by 42% in its capital with data sharing model

Wales reduced police-recorded violence by 42% in its capital by encouraging hospital emergency departments to share anonymised data with law enforcement. In the "Cardiff Model", data is analysed to isolate violence hotspots, giving policymakers information on where they should change alcohol licensing and pedestrianise streets. It has saved the city an average of $6.6 million a year in health, social and criminal justice costs.
