Thornaby-on-Tees recorded a crime rate of 15.0 per 1,000 in October 2024, placing it 85.2% above the UK average of 8.1. This figure, which reflects the highest rate in the area’s recent history, is driven by a combination of anti-social behaviour (25.8% of all crimes), violence and sexual offences (24.2%), and shoplifting (14.9%). The seasonal context of October—shorter days, the transition to British Summer Time, and the Halloween period—may partly explain the surge in anti-social behaviour, which is 202% above the UK average. The town’s character as a post-industrial urban centre with a mix of residential and retail areas likely contributes to the high levels of shoplifting and public order offences. While the overall rate remains concerning, the breakdown shows a nuanced picture: property crimes (including burglary and vehicle crime) account for 42.2% of all incidents, while violent crimes make up 24.2%. The UK comparison highlights systemic issues, with Thornaby-on-Tees’ rate being more than double the national average. This disparity may be attributed to the area’s socio-economic profile, including higher deprivation indices and limited public services compared to more affluent regions. The seasonal factors, combined with the area’s demographics, suggest that targeted interventions during peak periods, such as Halloween, could help mitigate rising anti-social behaviour.
