What this data can and can’t tell you
- Solved cases. A crime is cleared when police lay or recommend a charge, or solve it another way; the weighted rate counts serious crimes for more.
- 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. Figures are relative to one fixed point, Canada in 2006 at 100, rather than to this year’s national number.
