Milford Haven’s December 2023 crime rate of 9.2 per 1,000 residents—27.8% above the UK average—reflects a significant departure from national norms. With 152 crimes reported in a population of 16,485, this translates to one crime for roughly every 108 residents over the course of the month. The most prevalent category was violence and sexual offences, accounting for 52.6% of all incidents (80 cases), a figure 87% higher than the UK average. This dominance of violent crime, combined with elevated rates of criminal damage (96% above UK average) and public order offences (46% above), suggests a unique local dynamic. The area’s coastal location and seasonal tourism patterns may contribute to these trends, as extended evenings and holiday-related gatherings could heighten opportunities for conflict. Meanwhile, property crimes such as burglary and vehicle crime saw dramatic increases, linked to the holiday season’s impact on home security and vehicle storage. These patterns contrast with lower-than-average rates for shoplifting and other theft, which may indicate effective local measures or reduced retail activity during December. The seasonal context of December—characterized by dark evenings, Christmas shopping, and party season—likely plays a role in shaping these statistics, though the precise interplay of factors remains complex. This data underscores the need for tailored approaches to crime prevention that account for both local and national influences.
