This list shows metropolitan regions in the European Union by 2021 GDP according to
Eurostat. A
NUTS 3 region (or a group thereof) is considered to be a
metropolitan region, if at least 50% of its residents live inside a
functional urban area with a population of 250,000 or more. NUTS 3 regions not meeting this criterion are considered to be non-metropolitan regions. In some of the EU member states, there can exist differently defined areas of various sizes, which may also be called metropolitan regions. For example, the four distinct metropolitan regions of
Munich,
Augsburg,
Ingolstadt, and
Rosenheim, as defined by Eurostat, all lie within the area of the
Munich Metropolitan Region. == 2021 ranking of top four German metropolitan regions ==
