Dubai is the most populous city in the United Arab Emirates, located on the southeast coast of the Persian Gulf. The majority of Dubai is desert land, with its economy historically based on fishing, pearl trading, and oil, but now focused on business and tourism. Dubai has experienced extremely rapid urbanization and development of skyscrapers, villas, and new city districts, making it one of the fastest growing cities in the world. Its population is only 20% Emirati, with 80% comprised of expatriate workers from South Asia and other regions.
