“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.

27 violent and sexual offences in the last 12 months, against 43 the year before
“Towns its size” pools all UK towns of 1,000 to 2,500 people that police.uk covers each month (Greater Manchester has no data).
Rolling twelve-month rate, per 1,000 residents a year (longer windows for smaller places, where a few crimes swing a month). In the 12 months to August 2026 against the 12 before: violent -37% (towns its size +3%).
No one died in a collision on Gaerwen’s roads in 2021–2025
Police recorded 4 collisions with injuries inside Gaerwen in five years. 1 person was killed or seriously injured: 0 on foot and 0 on a bicycle.
Most UK towns of 1,000 to 2,500 people (94%) had no road deaths in these five years, and Gaerwen is one of them.
Counting serious injuries too, a town of Gaerwen’s size at the median for UK towns of 1,000 to 2,500 people would see about 1 people killed or seriously injured in five years; Gaerwen had 1.
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 Gaerwen 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.
