International Labor migration has powerful consequences for Algeria, Morocco and Tunisia. Economically, migration affects Maghribi foreign currency earnings, balance of payments, employment rates, entrepreneurship and national economic development generally. Politically, it affects both Maghribi internal politics and relations with Europe. The sociocultural effects of migration are perhaps the most profound, touching aspects of North African life such as dress, music, architecture and nutrition, as well as deeper levels of beliefs and values, such as family structures, child-rearing practices and gender roles—aspects of culture that have generally been thought to be resistant to change.
