The four leading regions in the ranking of regional GDP per inhabitant in 2006 were Inner London in the United Kingdom (336% of the average), the Grand Duchy of Luxembourg (267%), Bruxelles/Brussels in Belgium (233%) and Hamburg in Germany (200%). Among the 41 regions exceeding the 125% level, eight were in Germany, six in the United Kingdom, five in the Netherlands, four in Austria, three each in Spain and Italy, two each in Belgium and Finland, one region each in the Czech Republic, Denmark, Ireland, Greece, France, Slovakia and Sweden, as well as the Grand Duchy of Luxembourg.
It should be noted, however, that in some regions the GDP per inhabitant 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. The result is that GDP per inhabitant appears to be overestimated in these regions and underestimated in regions with commuter outflows.
…and one in four below 75%
The twenty lowest regions in the ranking were all in Bulgaria, Hungary, Poland and Romania, with the lowest figures recorded in Nord-Est in Romania and Severozapaden in Bulgaria (both 25% of the average), followed by Severen tsentralen (27%) and Yuzhen tsentralen (28%), both in Bulgaria. Among the 68 regions below the 75% level, fifteen were in Poland, seven each in Romania and the Czech Republic, six each in Bulgaria, Greece and Hungary, five in Italy, four each in France (all overseas departments) and Portugal, three in Slovakia, one region each in Spain and Slovenia, as well as Estonia, Latvia and Lithuania.
