Milford Haven’s built-up area recorded 139 crimes in December 2025, equating to 8.4 incidents per 1,000 residents—a figure 20% above the UK average of 7.0. This rate, while higher than national benchmarks, contrasts with a 23.2% month-on-month decline from November’s 11.0 per 1,000, suggesting localized factors may be influencing trends. The crime profile was dominated by violence and sexual offences (68 incidents, 48.9% of total), which were 60% above the UK average of 2.6 per 1,000. Anti-social behaviour (18 incidents) and public order offences (15 incidents) also significantly exceeded national rates, by 18% and 105% respectively. These patterns align with December’s seasonal dynamics: extended darkness, holiday-related foot traffic, and the closure of some homes during the festive period. The high proportion of violent crimes may reflect the area’s compact urban character, where public spaces are concentrated and nightlife activity persists even in winter. Meanwhile, the sharp drop in shoplifting (72.7% month-on-month) could be attributed to reduced retail hours or heightened police presence during the Christmas shopping peak. Property crimes, at 30 incidents, were lower than violent crimes but still accounted for 21.6% of the total, with burglary (4 incidents) and other theft (9 incidents) contributing to this category. The area’s crime profile thus illustrates a tension between persistent violent incidents and seasonal fluctuations in property-related offences, with the latter likely influenced by both environmental factors and community responses.
