“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.

A ward’s rate counts crimes where they happened, not where victims live. police.uk places each crime at an anonymous map point; some are named for the kind of place (a supermarket, a car park), and each row adds up every place of that kind in Ystrad Mynach. We show only these, never streets or homes.

Violent crime held steady over the year
“Towns its size” pools all UK towns of 10,000 to 50,000 people that police.uk covers each month (Greater Manchester has no data).
Rolling six-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 +2% (towns its size +1%), homes and vehicles +54% (towns its size -2%), shoplifting and theft -26% (towns its size +1%), anti-social behaviour +25% (towns its size -4%).
Two people died in collisions on Ystrad Mynach’s roads in 2021–2025
Police recorded 37 collisions with injuries inside Ystrad Mynach in five years, in which two people died (1 was a cyclist). 14 people were killed or seriously injured: 4 on foot and 1 on a bicycle.
That is about what is typical for UK towns of 10,000 to 50,000 people: at their median rate (0.9 deaths per 100,000 residents a year), a town of Ystrad Mynach’s size would see about 1 in five years. With numbers this small, a death or two either way changes the picture, so Ystrad Mynach’s own rate (3.4) is context, not a ranking.
Counting serious injuries too, Ystrad Mynach had 24.4 people killed or seriously injured per 100,000 residents a year, about the same as the median for UK towns of 10,000 to 50,000 people (23.8).
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 Ystrad Mynach 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.
