Letchworth’s overall crime rate in April 2023 stood at 7.1 crimes per 1,000 residents, marking a 5.3% reduction compared to the UK average of 7.5. This performance places the built-up area within North Hertfordshire among the safer regions in the country for this period. The most significant contributors to the crime picture were violence and sexual offences, which accounted for 29.7% of all reported incidents, followed by anti-social behaviour at 27.1% and criminal damage and arson at 11%. These patterns align with Letchworth’s character as a garden city with a mix of residential and commercial zones, where high foot traffic in certain areas may partly explain the prevalence of anti-social behaviour and property-related crimes. Seasonal factors also played a role: the Easter period and spring weather, which typically encourage increased outdoor activity, may have contributed to the relative stability of violent crime rates. However, the area’s lower-than-average burglary and vehicle crime rates suggest that well-maintained housing and parking infrastructure—common in planned communities like Letchworth—likely contribute to this trend. Theft from the person remained below the UK average, consistent with the area’s lower population density and reduced tourist activity compared to coastal or urban centres.
