Grantham’s built-up area recorded a crime rate of 7.4 per 1,000 residents in May 2025, placing it 8.6% below the UK average of 8.1. This overall rate masks significant variations in crime types, with anti-social behaviour emerging as a standout concern. At 2.2 per 1,000, anti-social behaviour accounted for nearly a third of all crimes, far exceeding the UK average of 1.4 per 1,000. This 55% disparity may reflect the area’s character as a mixed-use town with a blend of residential and commercial zones, where public spaces can become focal points for disorder. Violence and sexual offences, at 2.8 per 1,000, were slightly below the UK average (also 2.8 per 1,000), indicating a balanced trend in violent crime. Shoplifting, at 0.7 per 1,000, was 4% above the UK rate, likely tied to Grantham’s retail presence and tourist attractions. Seasonal factors may have influenced these patterns: May’s bank holidays and longer evenings could have driven anti-social behaviour, while warmer weather reduced vehicle crime. However, the overall decline in crime compared to April suggests broader positive trends, linked to community initiatives or increased policing during peak activity periods.
