What this data can and can’t tell you
- 100 is Canada in 2006. Figures are relative to one fixed point, Canada in 2006 at 100, rather than to this year’s national number.
- Cleared, not convicted. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
- What the index measures. 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.
- Shared across the MRC. The Sûreté du Québec reports by MRC, so the figures cover every municipality it polices there, Lachute among them.
