What this data can and can’t tell you
- An index, not a verdict. Statistics Canada builds the index from every crime police record, weighted by how seriously the courts treat it, and divides by the population. It adds a warning of its own: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
- A wider service area. The service that polices Delson reports once for its whole area, so the figures aren’t the town’s alone.
- The index’s scale. Statistics Canada set the national index at 100 for 2006; every figure here is read against that.
- What clearance means. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
