Jersey is the largest of the group of islands known as the Channel Islands, located in the English Channel some 100 miles from the south coast of England and only 10 miles from the French coast. The island has been self-governing since the 13th century and has its own parliament, legislature and taxation systems. The present population is some 85,000, the majority of whom live and work in St Helier, the island's capital. The island's economy is driven primarily by the financial services sector, which accounts for over 50% of GDP.
