The most surprising finding is the 10% elevation in anti-social behaviour compared to the UK average, despite Welham Green's overall safety. This may stem from the area's commuter demographics, where transient populations and local amenities create opportunities for disruptive activity. Bicycle theft, though still below the UK average, has surged by 300% YoY—likely due to increased cycling during the pandemic or insufficient secure parking infrastructure. Property crime remains low, with vehicle crime decreasing by 22.7% YoY, possibly reflecting improved car security measures. The rise in public order offences (+50% YoY) may correlate with seasonal events or local gatherings that amplify noise and disorder.
