Detention Valid: 25 February 2016 to 25 May 2016
All data below relate to 2015 and all comparisons are with 2014, unless indicated otherwise.
The number of people entering detention in 2015 increased by 7% to 32,446 from 30,364 in the previous year. Over the same period there was a 12% increase in those leaving detention (from 29,674 to 33,189).
There was a continuing decline in the proportion of detainees being removed or voluntarily departing the UK on leaving detention, from the most recent peak in the year ending March 2011 of 64% to 45% in 2015. Conversely, there was an increase in the proportion of detainees granted temporary admission or release, from 28% to 43%, and an increase in the proportion of detainees granted bail, from 6% to 10%, over the same periods.
As at the end of December 2015, 2,607 people were in detention, 25% lower than the number recorded at the end of December 2014 (3,462). The fall may be partially attributed to the closure of Dover IRC in October 2015 and changes to the detained fast track asylum process.
In the fourth quarter of 2015, 18 children entered detention and 20 children left. There were no children in detention as at 31 December 2015.
