Ystrad Mynach’s crime rate in October 2025 was 0.2 per 1,000, placing the built-up area 97.4% below the UK average of 7.7 per 1,000. This figure, the lowest recorded for the area in recent data, reflects an exceptionally low level of criminal activity compared to national trends. The monthly breakdown reveals that all reported crimes were violent, with no property-related offences recorded — a stark contrast to the UK average, where property crimes typically constitute a larger share of total incidents. Seasonal factors, including the transition to darker evenings and the timing of Halloween, may have influenced local patterns, though the area’s low crime rate suggests that these factors had limited impact. The absence of property crime reports is particularly notable, as it deviates from the UK profile where such offences often dominate. This anomaly may be attributed to local characteristics such as community cohesion, effective policing, or the area’s built-up nature, which could reduce opportunities for certain types of crime. The exceptionally low rate highlights Ystrad Mynach’s status as a relatively safe area, though residents should remain vigilant during periods of heightened seasonal activity. The data also indicates that violent crime, while present, remains far below national levels, reinforcing the area’s overall safety profile.
