Plymouth’s December 2023 crime rate of 7.6 per 1,000 residents places it 5.6% above the UK average of 7.2, marking a significant deviation from national trends. This figure, derived from 2,074 total crimes, highlights a shift in the local crime profile, with violence and sexual offences accounting for 44.6% of all reported incidents. This category’s rate of 3.4 per 1,000 is 30% above the UK average, a disparity that may be linked to the city’s urban density and the seasonal context of December. The month, characterised by dark evenings, holiday gatherings, and empty homes over Christmas, likely creates conditions conducive to violent crime. Anti-social behaviour and criminal damage also rose above UK averages, though these categories represented a smaller share of overall crime. Conversely, theft from the person and bicycle theft were 44% and 100% below the UK average, consistent with reduced outdoor activity during the festive season. The interplay between local geography and seasonal factors—such as the proximity of Plymouth’s harbours and the influx of visitors during the Christmas shopping peak—may partly explain these patterns. While the overall rate is higher than the UK average, specific categories like vehicle crime and burglary fall below national figures, illustrating the complexity of crime dynamics in a coastal urban area.
