December 2024 marked a 13.4% month-on-month decline in Portsmouth’s crime rate, falling to 9.4 per 1,000 residents—32.4% above the UK average. This figure underscores the area’s persistent challenges with crime relative to the national benchmark, though the monthly drop suggests seasonal influences may have played a role. Violence and sexual offences dominated the crime profile, accounting for 42.8% of all incidents and sitting 56% above the UK average. This category’s dominance aligns with Portsmouth’s character as a coastal city with a mix of urban and maritime activity, where late-night venues and the port’s operations could contribute to higher rates of violent incidents. Shoplifting, at 93% above the UK average, was the second most common crime, likely driven by the Christmas shopping surge and the city’s retail presence along the waterfront. Anti-social behaviour, however, was an exception, being 15% below the UK average—a trend that may reflect community initiatives or the temporary closure of certain venues during the holidays. The seasonal context of December—dark evenings, empty homes, and increased foot traffic in retail areas—likely amplifies risks for property crimes while simultaneously reducing opportunities for others, such as vehicle-related offences. These patterns suggest that while Portsmouth’s overall crime rate remains elevated compared to the UK, targeted interventions during the festive period may have had a measurable impact on certain categories.
