The crime profile of Caernarfon in December 2025 reveals a stark imbalance, with violent crimes and anti-social behaviour dominating the local landscape. Violence and sexual offences accounted for 44.4% of all reported crimes, a figure that is 98% above the UK average of 2.6 per 1,000. This category’s prevalence is consistent with the area’s character as a historic town with a compact built-up area, where dense residential and commercial zones may heighten tensions during the holiday season. Anti-social behaviour followed closely, contributing 18.8% of total crimes and 137% above the UK average. This spike may be partly explained by the seasonal context: December’s dark evenings, the closure of businesses, and the influx of tourists and visitors who may contribute to overcrowding in public spaces. Criminal damage and arson, at 12% of total crimes, were 169% above the UK average, a figure that may reflect the vulnerability of historic buildings to vandalism or the challenges of maintaining public spaces during periods of reduced local oversight. The overall crime rate of 11.6 per 1,000 residents places the area 65.7% above the UK average, a disparity that likely reflects both the unique demographics of the built-up area and the pressures of the holiday season. While shoplifting and public order offences showed declines, the dominance of violent and anti-social crimes suggests that local policing strategies may need to focus on addressing the root causes of these issues, such as the interplay between transient populations and the town’s historical and cultural assets.
