Treharris' crime profile in June 2023 reveals a combination of violent and property crime, with anti-social behaviour dominating the overall picture. The area recorded 49 crimes — 7.7 per 1,000 residents — placing it 9.4% below the UK average of 8.5. This lower-than-average rate, however, masks significant local variations: anti-social behaviour accounted for 36.7% of all crimes, far exceeding its UK average of 1.5 per 1,000. The seasonal context of June — the start of summer and longer daylight hours — may have contributed to increased social interactions in public spaces, potentially fueling anti-social incidents. Violent crimes (14) outnumbered property crimes (10), a shift that contrasts with typical patterns in built-up areas where property crime often dominates. This imbalance could reflect local factors such as the area's proximity to Merthyr Tydfil's urban core, where alcohol consumption and public gatherings are more common. While anti-social behaviour surged, other categories like burglary and vehicle crime remained well below UK averages, suggesting a mixed picture of local crime resilience. The dominance of anti-social behaviour may indicate underlying social tensions or challenges in managing public spaces during peak summer months, a pattern consistent with other small built-up areas in South Wales.
