“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.

How crime in St Dennis has moved
Devon & Cornwall Police published three months short or not at all (Sep 2023, Oct 2023 and Nov 2023), so the line breaks there and those months are left out of the rates. “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 +29% (towns its size +3%), homes and vehicles +16% (towns its size +0%), anti-social behaviour -60% (towns its size -1%).

Safety letters rank against every UK town of 1,000 or more; the order here is context only.
Graded crime per 1,000 residents a year, September 2023 to August 2026, counting from the least: towns ranked near St Dennis, and others in Cornwall.
For every 1,000 residents, about 47 violent and sexual offences in the 12 months to August 2026
A crime isn’t a victim: one person can report several, and crimes in a town centre often involve visitors rather than residents.
And about 16 burglaries, vehicle crimes or acts of criminal damage, plus 3 shoplifting and theft reports, in the 12 months to August 2026. Each dot is one resident; each coloured dot is one recorded crime.
No one died in a collision on St Dennis’s roads in 2021–2025
Police recorded 7 collisions with injuries inside St Dennis in five years. 2 people were 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 St Dennis is one of them.
Counting serious injuries too, a town of St Dennis’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; St Dennis 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
- Some months are short. Devon & Cornwall Police published September 2023, October 2023 and November 2023 only in part or not at all. Those months are left out of the rates, which average the months that were published in full; the raw counts include what was published.
- 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 St Dennis 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.
