What this data can and can’t tell you
- Reading the number. Statistics Canada set the national index at 100 for 2006; every figure here is read against that.
- Solved cases. Cleared means solved by police, charged or not; it says nothing about what courts decide.
- How serious, not how safe. Each incident counts by its seriousness, judged from court sentences, and the total is set per resident. As Statistics Canada puts it, “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
- A regional police service. Deux-Montagnes is policed by a service that covers other municipalities too, and Statistics Canada reports the service as a whole.
