The UK has a proud history of providing refuge to those who need our protection. Almost all asylum claims are processed in the community. Individuals will have their claim processed in detention only if they have claimed asylum after having been detained for removal, or if they present public protection concerns.
The department currently does not record the information on the criteria as set; how long the average period of immigration detention was for detained asylum seekers in 2018.
Information on people entering detention by age, sex and place of initial detention (as at year ending September 2018) is available in table dt_01_q of the detention tables, which can be found in the latest release of ‘Immigration Statistics’, available from the Home Office website at:
The table shows the figures broken down by those people who have claimed asylum at some point in the past.
