Knife injury patterns are shifting fast, and the gender and age gaps are only part of the story. In England and Wales, knife enabled offences reached 49,489 in the year ending March 2023, while 1,293 murders in the United States involved knives that same period. Put alongside findings like 85% of UK victims aged 10 to 29 being male and 70% of domestic knife attack victims being female, the contrasts raise a bigger question about what drives injuries and who they reach next.
