The most surprising finding is that anti-social behaviour is 10% above the UK average, despite the area's overall safety score being 8 points higher than the national average. Violence and sexual offences, though 45% below the UK average, remain the most common crime type, possibly linked to local social dynamics. Vehicle crime is 20% below the UK average, which may reflect fewer commuter parking zones compared to larger urban centres. However, anti-social behaviour's sharp 180.8% YoY increase is concerning and could be tied to seasonal factors or community-specific pressures. The decline in shoplifting (-29%) suggests effective local deterrents, while the rise in 'other crime' (+76.2%) hints at emerging patterns requiring further analysis.
