EU Migration: share of national populations coming from other EU member states 2023

Luxembourg is the European Union member state with the greatest share of its population being citizens of other EU member states, with almost 38 percent of people in the country coming from elsewhere in the EU. The small western European state has become a hub for immigration due to its status as one of the administrative centres of the EU (including being the location of the European Court of Justice and European Investment Bank), a key location for financial services companies, and due to its close proximity population centres of other member states such as France, Germany, and Belgium. 

Other countries with a large share of their population coming from elsewhere in the EU include Austria, Belgium, and Ireland, three countries which have seen increased intra-EU migration in recent years due to strong work opportunities in international organisations (Belgium and Austria) and multinational companies (Ireland).
