The Home Office publishes statistics on people entering detention in the ‘Immigration Statistics Quarterly Release’. Data on people entering detention under immigration powers by place of detention and sex, are published in Table Det_D01and on people in detention at the last day of each quarter in Table Det_D02 of the ‘immigration detention detailed datasets’. The ‘contents’ sheet contains an overview of all available data on detention.
Figures on people entering detention in Q3 2020 will be published on 26 November 2020. Information on future Home Office statistical release dates can be found in the ‘Research and statistics calendar’.
The figures published in Det_D01 relate to the first place of detention. If an individual enters immigration detention in another part of the detention estate, or in prison before being moved to Yarl’s Wood, they will be recorded under that centre. https://www.gov.uk/government/collections/immigration-statistics-quarterly-release https://www.gov.uk/government/statistical-data-sets/returns-and-detention-datasets#immigration-detention https://www.gov.uk/search/research-and-statistics?content_store_document_type=upcoming_statistics&organisations%5B%5D=home-office&order=release-date-oldest
