Knife crime statistics

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.

Recorded crime

The ONS publishes data on police recorded crime involving a knife or sharp instrument for a selection of serious violent offences. In the year ending March 2021, there were around 41,000 (selected) offences involving a knife or sharp instrument in England and Wales (excluding Greater Manchester Police Force).  This was 15% lower than in 2019/20 and 27% higher than in 2010/11. Recent trends in knife crime have been affected by undercounting in the Greater Manchester Police Force area prior to 2018/19. Increases in recorded offences since 2018/19 are directly related with improvements in recording practices.
