Organisations working with migrants in irregular situation or in the area of immigration detention have always reported that most detained migrants are from Maghreb and sub-Saharan countries. Out of 7,855 persons detained in 2018, 2,801 (36%) were from Morocco and 2,511 (32%) from Algeria. More recent statistics were not available at the time of writing of this report. In its annual report on the situation of CIEs, the Migrant Jesuit Service continued to denounce the lack of transparency by the Government in publishing and providing statistics on immigration detention.
The over-representation in detention of people from Maghreb or sub-Saharan Africa is explained by the fact that identity checks conducted by police are still mostly based on ethnic and racial profiling. The discriminatory attitude and incidents within the Spanish territory have been the subject of several reports and critiques, which persisted in 2021 and at the beginning of 2022.
