A wide range of types of migration can be observed in this region: large-scale emigration in many countries, recent mass immigration in the case of Greece, return migration, internal migration, internal and external forced migration, irregular migration, brain drain etc. These migratory phenomena occur within the context of EU migration policies and EU accession for some countries. Yet within this shifting migration landscape of migrant stocks and flows, the fundamental economic geography of different wealth levels and work opportunities is what drives most migration, now as in the past.
