A Region on the Move report series for the East and Horn of Africa has been the regional flagship publication since 2017. The report series provides an advanced understanding of the main migrant groups and the environment in which mobility takes place, with a focus on internal displacement and mixed migration flows along the major migration corridors of this region. A Region on the Move 2022, the tenth report in the series, explores mobility dynamics affecting the East and Horn of Africa region across its broader spectrum: from providing a regional overview of data and trends on international migrants to discussing specific groups of migrants, namely migrant workers, refugees, asylum seekers, internally displaced persons and irregular migrants along the main migratory corridors.
