What this data can and can’t tell you
- What 100 means. The index is scaled so that Canada as a whole scored 100 in its base year, 2006: a town at 50 has half that severity per resident.
- The clearance rate. A crime is cleared when police lay or recommend a charge, or solve it another way; the weighted rate counts serious crimes for more.
- Severity, weighed. Statistics Canada, which publishes the index, attaches a caution: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.” The number weighs each reported crime by its seriousness before dividing by residents.
- A wider policing area. Detachment figures cover the detachment’s whole area: Black Diamond together with the countryside and smaller places it polices.
