SG9 crime rate and statistics

Last 12 published months

September 2025 to August 2026. Street-crime records include anti-social behaviour.

Month-by-month totals

Street-crime records per 1,000 residents

Published street-crime records (including anti-social behaviour), September 2025 to August 2026, per 1,000 usual residents in the Census 2021.

859 records and 12,543 residents. Residents-only rates overstate crime where many people visit who do not live there, such as city centres, stations, and retail parks. Residents are counted at March 2021 while records are current, so areas with many newer homes can read higher.

No England and Wales comparison is shown, because not every force involved has published every month of this window.

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

Where records cluster in SG9

Records by part of SG9: the south 691, the north 606, the north-west 150, the north-east 77, the east 28, the centre 3.

North is at the top. Each hexagon is about 1.2 km across, the size the crime map uses zoomed out, and holds at least one of SG9's postcodes; darker ones hold more records. Hexagons at the edge also hold records from neighbouring districts, and SG9's records placed outside these hexagons are not drawn, so the map's counts won't add up to the page's total. Police place each record at an approximate public point, so this shows which parts of SG9 records cluster in, not where incidents happened. Explore SG9 on the crime map.

Highest and lowest published crime rates by postcode district

Deprivation where residents live

Covers 100.0% of the 12,543 Census 2021 residents of SG9.

England: English Indices of Deprivation 2025

Of these residents in England, 0.0% live in the most deprived 20% of England's neighbourhoods and 8.9% in the least deprived 20%.

Share of residents in each decile, from 1 (most deprived) to 10 (least deprived) of England's small areas. Shares are rounded, so they may not total 100%.

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.
