In 2013, regional GDP per capita, expressed in terms of purchasing power standards, ranged from 27% of the EU28 average in the French overseas department of Mayotte, to 325% of the average in Inner London in the United Kingdom.
The leading regions in the ranking of regional GDP per capita in 2013, after Inner London in the United Kingdom (325% of the average), were the Grand Duchy of Luxembourg (258%), Bruxelles/Brussel in Belgium (207%), Hamburg in Germany (195%), Groningen in the Netherlands (187%), Bratislava in Slovakia (184%), Stockholm in Sweden (179%), Île de France in France (175%) and Praha in the Czech Republic (173%). After Mayotte in France (27%), the lowest regions in the ranking were all in Bulgaria and Romania: Severozapaden (30%), Severen tsentralen (31%) and Yuzhen tsentralen (32%) in Bulgaria and Nord-Est in Romania (34%). It should be noted, however, that in some regions the GDP per capita figures can be significantly influenced by commuter flows. Net commuter inflows in these regions push up production to a level that could not be achieved by the resident active population on its own. There is a corresponding effect in regions with commuter outflows.
