What this data can and can’t tell you
- Severity, weighed. One robbery outweighs a run of minor thefts here, since every crime counts by the sentences courts give it. Statistics Canada adds: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
- One figure for the MRC. Where the Sûreté du Québec polices, Statistics Canada publishes one figure per MRC; Berthier-sur-Mer shares it with its neighbours.
- What 100 means. Statistics Canada set the national index at 100 for 2006; every figure here is read against that.
- The clearance rate. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
