For a city of 383,919 residents, August 2023 saw 4,347 crimes reported, equating to 11.3 crimes per 1,000 people. This rate is 39.5% higher than the UK average of 8.1 per 1,000, reflecting a pattern of elevated crime activity in Cardiff during the summer months. The most prevalent crime types were violence and sexual offences (26.4% of total crimes), anti-social behaviour (15.3%), and shoplifting (11.5%). These figures align with the seasonal rhythm of August, a peak holiday month that brings increased tourism and temporary population shifts. The high incidence of shoplifting may be linked to the city’s retail presence and summer shopping patterns, while anti-social behaviour could be influenced by the density of urban spaces and higher foot traffic. Public order offences, which rose to 10.3% of total crimes, may also be tied to the influx of visitors and the associated challenges of managing crowds in public areas. The data suggests that Cardiff’s crime profile during August is shaped by a combination of its urban character, seasonal dynamics, and the transient nature of its population during the summer. The rate of violence and sexual offences, at 3.0 per 1,000, is 14% above the UK average, a disparity that may reflect the city’s role as a major urban centre with a complex mix of social and economic factors. Meanwhile, shoplifting’s 117% above UK average highlights the vulnerability of commercial districts to theft, exacerbated by the summer months when retail activity is at its peak. These patterns underscore the need for targeted interventions during periods of high tourism and population flux.
