Chiswell Green’s anti-social behaviour rate in July 2023 was 41% above the UK average, marking a striking anomaly in an otherwise safer-than-average area. The overall crime rate stood at 7.0 per 1,000 residents, 15.7% below the UK average of 8.3. Violence and sexual offences accounted for 42.9% of all crimes, followed by anti-social behaviour (28.6%) and shoplifting (9.5%). This pattern aligns with the area’s seasonal rhythm: July, a peak summer month with schools out and tourism at its height, often sees increased social activity in local parks and community spaces. The high rate of anti-social behaviour may partly reflect the influx of visitors and the extended hours of outdoor activity typical of this time of year. Conversely, property crimes such as criminal damage and arson were 22% below the UK average, consistent with the area’s low levels of vehicle crime and theft from the person. The relative safety of Chiswell Green compared to the UK average is notable, particularly given its status as a built-up area within St Albans, which typically experiences higher crime rates than rural regions. However, the disproportionate rise in anti-social behaviour highlights the need for targeted interventions during peak summer months. The breakdown of violent crimes, which were 8% above the UK average, underscores the combination of population density and local dynamics from this data alone.
