Participation in the European Parliament Election has steadily declined since the start in 1979. In 2004 less than half (47.8%) of the voting-age population of the European Union used their right to vote. This has actualized questions asking if the European Parliament is a good representation of the European citizens. The paradigm when it comes to explaining the electoral turnout in the European Parliament Election is the second-order theory. Though the theory explains the low voter participation, it does not explain why the European Parliament Election has become a second-order election. Thus, in this thesis will search for the underlying variable explaining why the European Parliament Election is a second-order election. Through our research we find that distances are important in the European Union, and they create centres and peripheries within the European Union. By looking at Rokkan and Urwin‟s horizontal and vertical types of peripheries, where the vertical type consists of Rokkan and Urwin‟s three domain of social life, our research concludes that centre-periphery structures within the European Union are the underlying variable, explaining why the European Parliament Election is a second-order election.
