## How to read this measure

The Crime Severity Index is not an indicator of overall safety. 2019 is the first full year under revised reporting standards; compare earlier years with caution. Revised 2021 and 2022 data use updated crime weights. The previous year may be revised at each release. Northwest Territories includes Nunavut in 1998; they are separate from 1999.

## How this answer was calculated

The headline compares the first and last observations shown. Overall change is the last index value minus the first and is reported in index points; relative change is (last ÷ first − 1) × 100. Intermediate observations remain visible in the chart and exact values. This is descriptive and does not identify causes.
