There were 30,000 registered partner migrations in Flanders and Brussels between 2008 and mid-2011. Partner migrations are people from outside Europe who marry or live together with a resident of Flanders or Brussels. In 40% of the cases, the partner came from Morocco or Turkey, according to a study by the University of Ghent for the Flemish Minsiter of Integration Geert Bourgeois.
33% came from Morocco (10,000), and 11% (3,200) from Turkey. This is often follow-up migration, and the resident is also Moroccan or Turkish.
125,000 such migrants come to Belgium annually, and make up a large part of overall immigration to the country.
