Switzerland occupies the crossroads of Germanic and Romance Europe, as reflected in its four main linguistic and cultural regions: German, French, Italian and Romansh. Although the majority of the population are German-speaking, Swiss national identity is rooted in a common historical background, shared values such as federalism and direct democracy, as well as Alpine symbolism. Due to its linguistic diversity, Switzerland is known by a variety of native names: ''Schweiz''  (German); ''Suisse''  (French); ''Svizzera''  (Italian); and ''Svizra''  (Romansh). On coins and stamps, the Latin name, ''Confoederatio Helvetica'' – frequently shortened to "Helvetia" – is used instead of the four national languages. A developed country, it has the highest nominal wealth per adult and the eighth-highest per capita gross domestic product; it has been considered a tax haven. It ranks highly on some international metrics, including economic competitiveness and human development. Its cities such as Zürich, Geneva and Basel rank among the highest in the world in terms of quality of life, albeit with some of the highest costs of living in the world. In 2020, IMD placed Switzerland first in attracting skilled workers. The WEF ranks it the fifth most competitive country globally.
