The Permanent Migration Observatory of Andalusia (OPAM by its acronym in Spanish - Observatorio Permanente Andaluz de las Migraciones) is an initiative of the Directorate General for the Coordination of Migration Policies (Ministry of Presidency, Public Administration and Home Affairs). OPAM has the mission of gathering and disseminating reliable knowledge on international migration, its impact on the host society and its evolution in time. While focusing primarily on immigration in Andalusia, comparisons are made with respect both to other regions of Spain and to other European countries.
