Africa (sub-Saharan)

Beyond intraregional migration, sub-Saharan Africans migrate to North Africa, Europe, North America, and beyond. The research offered here focuses generally on two aspects of sub-Saharan migration: the outcomes for these migrants and their children once they have settled in their countries of destination, the United States among them, and the roles that diasporas and development policies can play in the economic improvement of these African nations.
