In Bahrain, petroleum (oil product) producing and processing is about 60% of the money from export, 60% of government money, and 30% of Gross Domestic Product. The economy has changed as the sales of oil have changed since 1985, for example, during and after the Persian Gulf War of 1990 - 1991. Bahrain has high quality communications and transport, and so the country is home to many international companies with business in the Persian Gulf. A large part of the country's income comes from petroleum products made from imported crude oil. There are several major industrial projects being built. Unemployment, especially among young people, and the decrease of both oil and water resources are major economic problems.
