What this data can and can’t tell you
- How serious, not how safe. 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.”
- Reading the number. 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.
- Solved cases. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
