Question to the Home Office:

To ask the Secretary of State for the Home Department, how many offences involving a knife were committed in (a) St Helens South and Whiston constituency, (b) Merseyside and (c) England and Wales in each of the last three years.

The Home Office collects data on the number of selected offences involving a knife or a sharp instrument recorded by the police in England and Wales at the police force areas level only.

Data on knife offences at the police force area level can be found in the Home Office Knife Crime Open Data Tables, available here: https://www.gov.uk/government/statistics/police-recorded-crime-open-data-tables

The Home Office does not hold information on the average age of the perpetrators of knife crimes. Information on the offenders is the responsibility of the Ministry of Justice.
