Medical Justice collates Home Office Immigration Detention statistics through regular Freedom of Information requests. These statistics have now been updated to the end of December 2024.  

The statistics cover the following thematic areas: 

The statistics are available here 

The top-line statistics for 2024 show that: 

  • 74 Rule 35 (1) reports, 35 Rule 35 (2) reports and 2,473 Rule 35 (3) reports were completed for people in detention. 
  • There were 715 Use of Force incidents at Brook House Immigration Removal Centre (IRC), 188 at Colnbrook IRC, 43 at Derwentside IRC, 34 at Dungavel IRC, 156 at Harmondsworth IRC, 76 at Tinsley House IRC and 151 at Yarl’s Wood IRC. 
  • 1292 ACDTs and 419 constant supervision ACDTs were opened. 
  • At least 1,340 people were held in segregation under Rule 40 and at least 25 under Rule 42. 
  • While 1292 ACDTs and 419 constant supervision ACDTs were opened in 2024, only 74 Rule 35 (1) reports and 35 Rule 35 (2) reports were completed in detention. This shows that high numbers of individuals have been identified as warranting observation for suicide or self-harm risk, but in all but a few cases, the clinical assessment and reporting process for risk of deterioration and risk of suicide has not been followed.
