“Violent” is police.uk’s violence and sexual offences (which includes harassment, stalking and assault without injury), robbery and possession of weapons. Anti-social behaviour isn’t a crime category; shoplifting and other theft happen mostly in shops and town centres rather than to residents, so neither counts in the grade.

Counting serious injuries too, a town of Trimley St Mary’s size at the median for UK towns of 2,500 to 10,000 people would see about 3 people killed or seriously injured in five years; Trimley St Mary had 2.
Casualties are counted where the collision happened, not where people lived: a main road through town adds through-traffic, and residents’ own risk on roads elsewhere isn’t here. Seriously injured uses the Department for Transport’s adjusted figures, which even out the police forces’ different ways of recording injuries. There’s no national rate here: more than half of road deaths in England and Wales (58%) happen outside every town’s built-up area. Source: DfT road casualty statistics (STATS19), 2021–2025.

What this data can and can’t tell you
- Where crimes happen, not where victims live. police.uk places each crime at a point near where it happened. Town centres with shops, stations, a hospital and nightlife record more crime per resident, and residents of nearby villages who come in to shop or go out are part of that count.
- Bigger towns record more per resident. Across UK towns, recorded crime per resident rises steeply with size, more than in the U.S., so a city’s grade sits low against the whole UK. The “towns its size” figures show where Trimley St Mary sits among towns like it; they are context and don’t change the grade.
- Points are approximate. police.uk moves each point to the nearest of a set of anonymous map points, so crimes near the edge of the built-up area can fall either side of it.
