This briefing looks at statistics on knife crime in England and Wales. It uses police recorded crime data to evaluate trends over time and to compare knife crime between police force areas, with a section focussing specifically on knife crime in London. Sentencing statistics are also used to look at outcomes of proven posession offences. The final section of this briefing examines NHS hospital data to supplement police and court data.

Police Recorded Crime

The Office for National Statistics (ONS) publishes data on crimes recorded by police involving a knife or sharp instrument for a selection of serious violent offences.

In the year ending March 2023, there were around 50,500 offences involving a sharp instrument in England and Wales (excluding Devon & Cornwall). This was 4.7% higher than in 2021/22 but 7% lower than in 2019/20.

Knife crime by police force area

ONS data shows that in 2022/23, West Midlands Police recorded the highest rate of 178 offences per 100,000 population. In contrast, the North Yorkshire recorded the lowest rate of 35 offences each, per 100,000 population.

Proven offences and offenders

Sentencing statistics from the Ministry of Justice shows that in the year ending March 2023, there were just over 19,000 cautions and convictions made for possession of a knife or offensive weapon. Juveniles (aged 10-17) were the offenders in around 18% of cases.

Hospital admissions

Police and courts crime data depends on offences being reported to the authorities, which is a weakness. To get a more rounded view on knife crime it is useful to supplement this information with alternative sources such as NHS hospital data.

Data from NHS Digital shows there were 3,775 “hospital episodes” recorded in English hospitals in 2022/23 due to assault by a sharp object. This was a 9.5% decrease compared to 2021/22, and a 3.6% increase compared to 2014/15.
