Since reunification, approximately 1.5 million people have left the former East Germany. In the states of Thuringia, Saxony, Saxony-Anhalt and Mecklenburg-Western Pomerania, population numbers have reduced by between eight and twelve percent, since the time of reunification. In the western states there are also shrinking regions: in the Ruhr Basin, Saarland and along the former German-German border. Economically strong areas in the West have profited from the migration of young and qualified people. Particularly Bavaria and Baden-Wurttemberg have been able to increase their population, and both states continue to benefit from internal migration.
