What this data can and can’t tell you
- The clearance rate. Police clear an incident by charging someone, recommending a charge, or closing it another way. The rate weighs serious crimes more, as the index does.
- Severity, weighed. The index weighs crimes rather than counting them: a serious offence moves it far more than a minor one. Statistics Canada is plain about its limits: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
- One service, several municipalities. Longueuil is policed by a service that covers other municipalities too, and Statistics Canada reports the service as a whole.
- What 100 means. A reading of 100 is the whole country in 2006. Half of that, 50, means half the severity per resident.
