Diss, a built-up area within South Norfolk, continues to outperform the UK average in crime prevention, with a recorded rate of 6.3 crimes per 1,000 residents in July 2025—26.7% below the national average of 8.6. This performance is particularly notable given the area’s seasonal dynamics, as July typically sees increased foot traffic from tourism, festivals, and outdoor events. The most prevalent crime category was violence and sexual offences (30 cases, 48.4% of total), a figure that sits just 1% below the UK average for this category. This may reflect the heightened social activity associated with the summer months, though the relatively low rate compared to other areas suggests effective local policing or community engagement. Property crimes, including shoplifting (6 cases) and criminal damage (5 cases), accounted for 25.8% of the total, but both categories remain below their respective UK averages. The sharp decline in anti-social behaviour (5 cases, 68% below UK average) could indicate improved community cohesion or targeted interventions, though further analysis would be required to confirm this. The breakdown also highlights a 150% increase in bicycle theft compared to the UK average, which may be linked to the influx of cyclists during summer events. As the area navigates its peak season, the balance between crime prevention and managing increased activity remains a key focus for local authorities.
