What this data can and can’t tell you
- Cleared, not convicted. Cleared means solved by police, charged or not; it says nothing about what courts decide.
- What the index measures. 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.”
- Shared policing. The service that polices Thorold reports once for its whole area, so the figures aren’t the town’s alone.
- 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.
