Carmarthenshire’s crime rate in December 2025 stood at 6.5 per 1,000 residents, a figure 7.1% below the UK average of 7.0. This performance underscores the area’s consistent efforts to maintain public safety, particularly during the festive season. The most prevalent crime type was violence and sexual offences, accounting for 45.8% of all reported incidents, followed by criminal damage and arson at 13.7%. These figures align with the seasonal context of December, which brings heightened activity in retail and social spaces, potentially contributing to higher violent crime rates. Conversely, the area’s relatively low property crime rate—particularly for burglary (0.2 per 1,000) and vehicle crime (0.1 per 1,000)—suggests effective community policing or environmental deterrents. The seasonal context of December, with its dark evenings and holiday-related absences, may have influenced patterns of criminal damage. Anti-social behaviour saw a 31.9% drop compared to the previous month, reflecting community initiatives or seasonal shifts in social dynamics. The interplay between local geography, population density, and seasonal rhythms likely plays a role in shaping these trends, though further analysis would be needed to confirm specific causal links.
