What this data can and can’t tell you
- The clearance rate. Weighted like the index, so solving one assault counts for more than solving a mischief; a charge laid, recommended or otherwise resolved all count.
- Severity, weighed. 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.
- One figure for the MRC. The Sûreté du Québec’s figures are for its MRC as a whole, not for Thetford Mines alone.
- What 100 means. A reading of 100 is the whole country in 2006. Half of that, 50, means half the severity per resident.
