1. Key facts

The number of people entering detention in year ending March 2016 increased by 4% to 32,163 from 30,902 in the previous year.

Over the same period there was an 8% increase in those people leaving detention (from 30,326 to 32,610). There was a continuing decline in the proportion of detainees being removed or voluntarily departing the UK on leaving detention in the year ending March 2015 of 51% to 45% in year ending March 2016. Conversely, there was an increase in the proportion of detainees granted temporary admission or release (TA/TR), from 39% to 44%.

As at the end of March 2016, 2,925 people were in detention, 16% lower than the number recorded at the end of March 2015 (3,483). The fall may be partially attributed to the closure of Haslar IRC in April 2015 and Dover IRC in October 2015, and changes to the detained fast track asylum process, as well as changes in the numbers of people requiring detention.
