Switzerland
The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita). In 2017, average gross household income in Switzerland was 9,946 francs per month (equivalent to US$10,720 per month), though 61% of the population made less than the average income. Switzerland also has one of the world's largest account balances as a percentage of GDP.
