The Home Office publishes data on people in detention and returns from the UK in the ‘Immigration Statistics Quarterly Release’ (

Data on the number of people in detention under immigration powers by quarter and nationality are published in table Det_D02 of the immigration detention detailed datasets (

Data on the number of returns from the UK by type of return and destination are published in Ret_D02 of the returns detailed datasets (

The term 'deportations' refers to a legally-defined subset of returns which are enforced either following a criminal conviction or when it is judged that a person’s removal from the UK is conducive to the public good. Information on those deported is not separately available and therefore the published statistics refer to all enforced returns.

Additionally, the Home Office publishes a high-level overview of the data in the ‘Summary tables’ ( The ‘contents’ sheet contains an overview of all available data on detention.

A statistical report Statistics relating to Covid-19 and the immigration system, May 2020 (, released on 28 May 2020 provides further high-level information relating to detention and Covid-19 up to the end of April.

Figures covering the second quarter of 2020 will be published in the next Immigration Statistics release on 27 August 2020. Information on future Home Office statistical release dates can be found in the ‘Research and statistics calendar’ (
