The European Union (EU) is a politico-economic union of 28 member states that are located primarily in Europe. It covers an area of 4,324,782 km2, with an estimated population of over 508 million. The EU operates through a system of supranational institutions and intergovernmental-negotiated decisions by the member states. The institutions are: the European Parliament, the European Council, the Council of the European Union, the European Commission, the Court of Justice of the European Union, the European Central Bank, and the Court of Auditors. The European Parliament is elected every five years by EU citizens.
The EU has developed an internal single market through a standardised system of laws that apply in all member states. Within the Schengen Area, passport controls have been abolished. EU policies aim to ensure the free movement of people, goods, services, and capital, enact legislation in justice and home affairs, and maintain common policies on trade,agriculture,fisheries, and regional development. The monetary union was established in 1999 and came into full force in 2002. It is currently composed of 19 member states that use the euro as their legal tender.
