The Swiss (German: die Schweizer, French: les Suisses, Italian: gli Svizzeri, Romansh: ils Svizzers) are citizens or natives of Switzerland. The demonym derives from the toponym of Schwyz and has been in widespread use to refer to the Old Swiss Confederacy since the 16th century. The number of Swiss nationals has grown from 1.7 million in 1815 to 6.76 million in 2009, 90% of them living in Switzerland. About 60% of those living abroad reside in the European Union (446,412). The largest groups of Swiss descendants and nationals outside of Europe are found in the United States and Canada.
