With a population of about 8.9 million and a nominal GDP of roughly US$885 billion, Switzerland is one of the world’s wealthiest economies, with GDP per capita near US$100,000. It is a member of EFTA and the Schengen Area, but is not part of the EU or the EEA, operating instead through a framework of bilateral agreements. Its currency is the Swiss franc. In this index it is represented by the Lump-Sum regime, a tax-residence arrangement that reflects Switzerland’s appeal to globally mobile high-net-worth individuals.
