One of the most important unions in the world with the power of directing the world economy is the European Union (EU), which has 27 members by the year 2007. Starting with 6 members in 1957, the EU expanded with new participations. Participation of other members brought up the discussion of the economical and social differences and imbalances between the member countries. This paper deals with this discussion's economical side and brings a mathematical view with Data Envelopment Anaysis which is a mathematical modelling method of calculating relative efficiencies of Decision Making Units (DMUs), based on predetermined inputs and outputs. DMUs are the EU member countries and inputs-outputs are economic indicators. After finding the relative efficiencies of the member countries, the results are discussed.
