How is the Dorchester safety index calculated?
SafeRoute weights each incident reported to the Boston Police Department by severity (violence weighs more than shoplifting), sums the last available period within 1 km of the neighborhood center, and normalizes against citywide crime rates onto a 0–100 scale — higher is safer. It describes reported crime only; it is not a guarantee of safety.
