Switzerland, officially the Swiss Confederation, is a federal republic consisting of 26 cantons, with Bern as the seat of the federal authorities. The country is situated in Western Europe where it is bordered by Germany to the north, France to the west, Italy to the south, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Central Plateau and the Jura. Its area is 41,285 km2. The Swiss population of approximately 7.8 million people concentrates mostly on the Plateau, where the largest cities are to be found. Switzerland is one of the richest countries in the world by per capita gross domestic product, with a nominal per capita GDP of $67,384. Zürich and Geneva have respectively been ranked as the cities with the second and third highest quality of life in the world. The Swiss Confederation has a long history of neutrality—it has not been in a state of war internationally since 1815—and did not join the United Nations until 2002. Switzerland is home to many international organisations, including the World Economic Forum, the International Olympic Committee, the Red Cross, the World Trade Organization, FIFA, and the second largest UN office. On the European level it was a founder of the European Free Trade Association  and is part of the Schengen Agreement - although it is notably not a member of the European Union, nor the European Economic Area.
