OIMWith an increase of just over half a million from 16.to 16.9 million between 2000 and 2005, Africa experienced the lowest growth rate in international migrants of any region in the world, and, at two per cent, the continent also registers the lowest proportion of migrants as a share of the population. Its share of the global migrant stock has remained stable at nine per cent (UN DESA, 2005).
Migrants are widely distributed across the continent, with a disproportionate impact on sub-Saharan countries. In absolute terms, it is the large Western and Southern African countries that are most affected, but relative to the size of their population the smallest countries receive more migrants.
Most of the recorded migration in Africa occurs within the region; out of a total of 14.5 million migrants originating in sub-Saharan Africa, 10 million migrants (or 69%) move within the region (Ratha and Shaw, 2007).
Africa has the world’s largest concentration of internally displaced persons (IDPs), with 11.8million in 21 countries in 2006 (IDMC, 2007), largely outnumbering the refugee population which declined from about 6 million to about 3 million in the 1995-2005 decade (UNHCR, 1995and 2007b).
Refugees as a percentage of total international migrants decreased by four percentage points to 18 per cent of the current migrant population (UN DESA, 2005 ).
Africa received USD 19.4 billion in remittances in 2006, the smallest share of global transfers (World Bank, 2007).
Coastal migration and environmental migration are among the emerging features of migration in Africa.
