Budget

One problem with this data is that in some areas, including Greater London, are subject to a large number of commuters coming into the area, thereby artificially inflating the figures. It has the effect of raising GDP but not altering the number of people living in the area, inflating the GDP per capita figure. Similar problems can be produced by a large number of tourists visiting the area. The data is used to define regions that are supported with financial aid in programs such as the European Regional Development Fund. The decision to delineate a Nomenclature of Territorial Units for Statistics (NUTS) region is to a large extent arbitrary (i.e. not based on objective and uniform criteria across Europe), and is decided at European level (See also: Regions of the European Union).

The 10 NUTS-1 and NUTS-2 regions with the highest GDP per capita are all in the first fifteen member states: none are in the 12 new member states that joined in May 2004 and January 2007. The NUTS Regulation lays down a minimum population size of 3 million and a maximum size of 7 million for the average NUTS-1 region, whereas a minimum of 800.000 and a maximum of 3 million for NUTS-2 regions ¹ . This definition, however, is not respected by Eurostat. E.g.: the région of Île-de-France, with 11.6 million inhabitants, is treated as a NUTS-2 region, while the state of Bremen, with only 664,000 inhabitants, is treated as a NUTS-1 regionCurrency
