How is the Safety Index calculated?
We rank each place against others in the same country by its rate per person of violent crime (half the weight) and of property crime: break-ins, car theft and theft (the other half). The index is the share of places with a higher combined score. Where a police service did not report car thefts, its property crime is ranked on break-ins and theft only. It uses police-reported crime only, which depends on how often residents report. Full method, sources and a worked example.
