What this data can and can’t tell you
- Solved cases. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
- How serious, not how safe. 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.”
- Town and surroundings together. An RCMP or OPP detachment reports one set of figures for everywhere it polices, so Corunna’s are shared with its surroundings.
- Reading the number. Figures are relative to one fixed point, Canada in 2006 at 100, rather than to this year’s national number.
