Holyhead's November 2023 crime rate of 10.0 per 1,000 residents places it 33.3% above the UK average of 7.5 per 1,000, a stark contrast to the national trend. This elevated rate is driven primarily by violence and sexual offences, which account for 48.4% of all reported crimes, followed by anti-social behaviour (18.9%) and criminal damage and arson (9.8%). These figures suggest a combination of local demographics and seasonal factors, with November's darker evenings and Bonfire Night likely contributing to spikes in violent and anti-social incidents. The area's coastal location and status as a major port may also influence crime patterns, with transient populations potentially exacerbating issues like drug-related offences, which are 200% above the UK average. Meanwhile, the UK's overall decline in shoplifting—mirrored in Holyhead's 76.9% drop from 13 to 3 cases—points to broader retail security improvements. However, the persistence of high violent crime rates, which are 89% above the national average, indicates a need for targeted interventions. Local factors such as the proximity to the Menai Strait, which sees significant maritime activity, and the area's role as a regional transport hub could explain the elevated levels of anti-social behaviour and criminal damage. These patterns are consistent with other coastal towns where seasonal events and transient populations contribute to crime fluctuations.
