By the early 2000s, the Republic had become the second richest (in terms of GDP per capita, adjusted for purchasing power parity) member of the European Union, had moved from being a net recipient of EU funds to a net contributor, and from a position of net emigration to one of net immigration. In 2005, its "per capita" GDP (adjusted for purchasing power parity) became the second highest in the world (behind Switzerland) with 10 percent of the population born abroad. The population grew to an all-time high for the state of about 4.5 million.
