What this data can and can’t tell you
- Town and surroundings together. Detachment figures cover the detachment’s whole area: Alliston together with the countryside and smaller places it polices.
- Reading the number. Canada’s own index has been below its 2006 base of 100 for years, so 100 marks a fixed reference, not today’s national average.
- Solved cases. Police clear an incident by charging someone, recommending a charge, or closing it another way. The rate weighs serious crimes more, as the index does.
- How serious, not how safe. The Crime Severity Index adds up police-reported crime, each kind weighted by the sentences courts give it, so one robbery counts for more than many thefts. In Statistics Canada’s words, “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
