The requested information is not held centrally and would be available through the detailed examination of individual case files only at disproportionate cost.
The following table shows the numbers of children detained within the UK Border Agency detention estate solely under Immigration Act powers on a snapshot basis as at the last Saturday of each quarter of 2008, broken down by length of detention.
National Statistics on children detained solely under Immigration Act powers on a snapshot basis are published quarterly. This information is published in tables 9-11 of the Control of Immigration: Quarterly Statistical Summary, United Kingdom bulletins which are available from the Library of the House and from the Home Office’s Research, Development and Statistics website at:

Children are detained only in the following limited circumstances: most usually, as part of a family group whose detention is considered necessary; exceptionally, when unaccompanied, while alternative care arrangements are made and normally just overnight; to facilitate supervised escort of an unaccompanied child, who is being removed, from his/her normal place of residence to the port where removal will take place—detention occurs only on the day of the planned removal to enable the child to be properly and safely escorted to his/her flight and/or to their destination; and in exceptional circumstances where it can be shown that an ex-foreign national prisoner aged under 18 poses a serious risk to the public and a decision to deport or remove him/her has been taken.
The Government’s stated policy on detention of families with children is set out in the 1998 White Paper “Fairer, Faster and Firmer—A Modern Approach to Immigration and Asylum”. In all cases there is a presumption in favour of temporary admission or temporary release and all reasonable alternatives to detention are considered before detention is authorised.
