As at the end of June 2016, 2,878 people were in detention, 16% lower than the number recorded at the end of June 2015 (3,418). The fall may be partially attributed to the closure of 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.
