Question to the Ministry of Justice:

To ask the Secretary of State for Justice, pursuant to the Answer of 14 July 2022 to Question 31829 on Prisoners: Location and the Answer of 24 March 2022 to Question HL6866 on Prisoners: Females, what the average travelling distance between (a) female and (b) male prisons and the prisoner's home address was in each year since 2010.

Although travelling distance from home was historically provided on an ad hoc basis for specific time frames, this calculation method was discontinued in 2019 and replaced with straight-line modelling.

Straight-line modelling is the most consistent calculation method. Attempts to model based on travelling distance are subject to high levels of temporal and geographical variation (e.g. inner city travel time).

As such, the information requested is deemed less useful than straight-line modelling data. It is therefore not routinely calculated and is not currently held.
