Question to the Home Office:

To ask the Secretary of State for the Home Department, how many people were detained under immigration powers in a prison at the end of their sentence in 2021; and how many of those people were subsequently released back into the community at the end of their period of detention.

The Home Office publishes statistics on people entering, leaving and in immigration detention in the ‘Immigration Statistics Quarterly Release’. The number of people in detention at the end of each quarter are in table Det_02 of the ‘Detention detailed datasets’ and can be broken down by place of detention including by ‘H M Prisons’ with the latest data relating to the end of March 2022.

Data on in detention counts the number of people in detention on the last day of the period (e.g. 31 December).

Information on how to use the dataset can be found in the ‘Notes’ page of the workbook.

The number of people leaving detention by reason for leaving are in table Det_04a of the ‘Detention summary tables’ with the number of people leaving detention by last place of detention (including ‘H M Prisons’) are in table Det_04c of the ‘Detention summary tables’ with the latest data relating to the year ending March 2022.

Last place of detention does not show where an individual spent their time in detention. In some cases, an individual may have spent a period of time detained elsewhere before being moved to their last place of detention.
