Question to the Home Office:

To ask the Secretary of State for the Home Department, how many (a) police officers and (b) full-time equivalent police officers there were in each local authority area in the Liverpool City Region in each year since 2010.

The Home Office collects and publishes data annually on the number of police officers, by Police Force Area, as part of the ‘Police workforce, England and Wales’ statistical bulletins.

Data on the number of officers, by headcount and by full-time equivalents, in Merseyside, and in England and Wales, going back to March 2007, can be found in the Open Data Tables published alongside the release:

Data at lower levels of geography are not held centrally.

The next release of ‘Police workforce, England and Wales’ is scheduled on Thursday 18 July 2019, and will cover the situation as at 31 March 2019.
