First-level NUTS of the European Union

The Nomenclature of Territorial Units for Statistics (NUTS) is a hierarchical system for dividing up the economic territory of the European Union and the European Economic Area. The first level of NUTS (NUTS-1) refers to major socio-economic regions within EU member states. As of October 2023, the EU has several first-level NUTS regions that correspond roughly to the larger administrative divisions or regions within each member state.
