For a population of 10,116, Caernarfon recorded 142 crimes in August 2023, a rate of 14.0 per 1,000 residents—72.8% above the UK average of 8.1 per 1,000. This stark divergence from national trends highlights the area’s unique challenges, particularly in violent crime, which accounted for 44.4% of all incidents. Violence and sexual offences, at 63 cases, dominated the crime picture, significantly exceeding the UK average by 135%. Anti-social behaviour followed closely with 38 incidents, 164% above the UK rate, while criminal damage and arson added 12 cases, 90% above the national figure. The seasonal context of August—a peak holiday month—likely contributes to these patterns, with increased tourism potentially straining local resources and leaving properties unoccupied, heightening burglary risks. However, the data also reveals uneven trends: shoplifting dropped sharply by 56.3%, possibly due to targeted retail security efforts or reduced foot traffic during holidays, while theft from the person rose by 100%, indicating vulnerabilities in public spaces. The area’s built-up nature, with a mix of residential and commercial zones, may amplify anti-social behaviour and violent incidents in densely populated areas. Despite the overall high rate, the month-on-month decline of 4.7% from July’s 14.7 per 1,000 suggests some mitigating factors, though the scale of violent crime remains a pressing concern. This snapshot underscores the need for tailored strategies addressing both the immediate spikes in violent crime and the underlying social dynamics shaping Caernarfon’s crime profile.
