Mountain Ash’s crime rate of 94.9 per 1,000 residents is 4.1% above the UK average, but the sharp 150% YoY increase in robbery stands out. While property crime is 32.4% below the UK average, the spike in violent crime and rising robbery rates highlight complex local dynamics. This data reveals both risks and opportunities for targeted safety improvements.

Mountain Ash is a built-up area in Rhondda Cynon Taf, historically shaped by coal mining and now transitioning to a commuter hub. Its proximity to urban centres and mixed demographics likely contribute to higher rates of violence and anti-social behaviour. The area’s compact layout and limited public transport may also influence patterns of property crime and vehicle-related incidents.

The most striking finding is that violence and sexual offences in Mountain Ash are 43% above the UK average, with 46.2 crimes per 1,000 residents. This may reflect the area’s younger population and proximity to nightlife venues, where alcohol-fuelled incidents are more common. Conversely, anti-social behaviour is 22% below the UK average, possibly due to community cohesion or effective local policing. Public order crimes, however, are 59% above the UK average, likely linked to crowded public spaces and transient populations. Vehicle crime is 10% above the UK average, potentially tied to commuter parking areas and unsecured vehicles. These disparities highlight how geography, demographics, and local infrastructure intersect to shape crime profiles.
