In October 2024, Portsmouth recorded 2463 crimes, translating to a crime rate of 11.5 per 1,000 residents—42% above the UK average of 8.1 per 1,000. This figure, when contextualised for Portsmouth’s population of 214,321, means that the area experiences approximately one crime for every 87 residents over the course of the month. The most prevalent crime type was violence and sexual offences, accounting for 40.3% of all reported incidents, followed by anti-social behaviour (10.5%) and public order offences (9.2%). These patterns align with Portsmouth’s character as a coastal urban centre with a mix of residential, commercial, and tourist areas. The high rate of violence may be influenced by the city’s nightlife and public spaces, which can see increased activity during darker autumn evenings. Meanwhile, public order offences, which are 96% above the UK average, could reflect the impact of Halloween events and seasonal gatherings. The seasonal context of October—shorter days, clocks going back, and the approach of winter—may also contribute to a rise in anti-social behaviour, as reduced daylight hours and colder weather can affect community dynamics. However, direct causal links, and factors such as local policing strategies, community engagement, and socioeconomic conditions likely play a role in shaping these trends. The overall crime rate, while concerning, provides a clear benchmark for understanding how Portsmouth’s crime profile compares to national standards, highlighting areas where targeted interventions may be necessary.
