A metropolitan region's gross domestic product, or GDP, is one of several measures of the size of its economy. Similar to GDP, GMP is defined as the market value of all final goods and services produced within a metropolitan region in a given period of time.
This list shows metropolitan regions in the European Union by 2021 GDP according to Eurostat. [1]
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 criteria are considered to be non-metropolitan regions. [2]
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. [3] [4]
