For every 1,000 residents in Thornbury, 5.9 crimes were reported in September 2025, a rate 20.3% below the UK average of 7.4 per 1,000. This relatively low per-capita risk is shaped by the area's character as a historic market town with a mix of residential and commercial zones. Violence and sexual offences accounted for nearly half (46.3%) of all crimes, reflecting the impact of seasonal rhythms such as the return to school and university freshers' week, which may contribute to increased social interactions and associated incidents. Anti-social behaviour (20.7%) and public order offences (9.8%) followed, aligning with the town's compact built-up area where noise and disorder can more easily escalate. The UK average comparison highlights Thornbury's strength in property-related crimes, which are 51% below the national rate for shoplifting and 64% lower for burglary. This may be attributed to the town's smaller scale, limited retail density, and strong community engagement, though the seasonal context of September—nights drawing in and the start of term—likely influences the balance between violent and property crimes. The data also suggests a slight uptick in violent incidents compared to the UK average for this category, a trend that could be linked to the concentration of younger residents in the area.
