Street-crime records per 1,000 residents

15% of this area's records sit at postcodes created after Census Day 2021, whose residents the census could not count, so no rate is shown.

Rates cover England and Wales only. Residents: Office for National Statistics, Census 2021 postcode estimates, Open Government Licence v3.0. How rates are built.

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.

Share of residents in each decile, from 1 (most deprived) to 10 (least deprived) of England's small areas.

Deciles rank neighbourhoods within one nation, so English and Welsh deciles don't compare. They describe areas, not the people living in them, and crime is one of the things the index measures, so this mix partly overlaps the crime figures above. How this is built.
