What this data can and can’t tell you
- What 100 means. Figures are relative to one fixed point, Canada in 2006 at 100, rather than to this year’s national number.
- The clearance rate. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
- 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. The service that polices Chambly reports once for its whole area, so the figures aren’t the town’s alone.
