The economy of Saint Barthelemy is based upon high-end tourism and duty-free luxury commerce, serving visitors primarily from North America. The luxury hotels and villas host 70,000 visitors each year with another 130,000 arriving by boat. The relative isolation and high cost of living inhibits mass tourism. The construction and public sectors also enjoy significant investment in support of tourism. With limited fresh water resources, all food must be imported, as must all energy resources and most manufactured goods. Employment is strong and attracts labor from Brazil and Portugal. Current Exchange Rate for Saint Barts
