How is the Grangetown safety index calculated?
SafeRoute weights each police-recorded incident by severity (violence weighs more than shoplifting), sums the last published month within 1 km of the ward centre, and normalises against Cardiff rates onto a 0–100 scale — higher is safer. It describes reported crime only; it is not a guarantee of safety. The scale is calibrated within Cardiff, so scores compare wards to each other and cannot be read against another city's.
