Barnham (Arun) experienced a 17.2% rise in its overall crime rate in September 2025 compared to August, but the area still maintained a rate of 5.8 per 1,000 residents—21.6% below the UK average of 7.4. This relative safety, despite the increase, may be attributed to the built-up area’s characteristics, such as its smaller population and community-focused infrastructure. The most prevalent crimes were violence and sexual offences (27.1% of total), followed by anti-social behaviour (20.8%) and burglary (14.6%). These figures align with patterns often seen in mixed-use urban areas, where high foot traffic and community events can influence crime dynamics. The seasonal context of September—marked by back-to-school activities and the start of university terms—may have contributed to the surge in criminal damage and arson (a 500% increase), as evenings grow darker and public spaces become more crowded. However, the decline in vehicle crime (50%) and public order offences (33.3%) suggests that some crime types are seasonal or influenced by specific local factors, such as reduced commuter traffic. The area’s violence and sexual offence rate being 38% below the UK average could reflect effective policing or the absence of high-risk environments typically associated with higher violent crime rates, such as nightlife hubs or densely populated urban centres. This data, while showing a rise in certain categories, still positions Barnham as a comparatively safe area within the UK’s broader crime profile.
