Limits to keep in mind

Published locations are approximate; they are snapped to anonymous map points before release, and each record is assigned to a sector by its nearest postcode. A sector is small, so counts near its edges are indicative.
These are counts of published police records, not all crime, and not a safety score.
Full detail is on the methodology page and in what a postcode district crime page shows, which covers sectors too.
