Ystrad Mynach’s crime rate in March 2025 stood at 9.7 per 1,000 residents — 24.4% above the UK average of 7.8 per 1,000. This places the area squarely above national trends, with violent crimes dominating the landscape. Violence and sexual offences accounted for 46.7% of all recorded crimes, a rate of 4.5 per 1,000 — 65% above the UK average. Anti-social behaviour followed closely, at 20.6% of all crimes (2.0 per 1,000), also significantly higher than the national rate. These figures reflect a pattern that aligns with the area’s built-up character, where social interactions in public spaces may contribute to higher reports of disorder. March’s transition to spring, with longer evenings and the clocks changing, may have influenced activity patterns, increasing opportunities for anti-social behaviour and public order offences. The data also reveals a stark contrast in categories: while violent and anti-social crimes are well above the UK average, property-related crimes such as burglary (0.1 per 1,000) and shoplifting (0.2 per 1,000) are below national rates. This divergence could be attributed to the area’s specific demographics or local policing strategies. The seasonal context of March, with its mix of post-winter fatigue and the onset of spring, may have played a role in the sharp increase in anti-social behaviour. However, without further data, such connections remain speculative. The overall picture suggests that while Ystrad Mynach is not a high-crime area in absolute terms, its violent and disorderly crime trends are higher than the UK average, requiring targeted attention from local authorities.
