Dubai is the most populous city in the United Arab Emirates (UAE). It is located on the southeast coast of the Persian Gulf and is one of the seven emirates that make up the country.
Dubai has emerged as a global city and business hub of the Middle East and South Asia. It is also a major transport hub for passengers and cargo.
Dubai's oil revenue helped accelerate the early development of the city, but its reserves are limited and production levels are low: today, less than 5% of the emirate's revenue comes from oil. The emirate's Western-style model of business drives its economy with the main revenues now coming from tourism, aviation, real estate, and financial services.
As of 2012, Dubai is the 22nd most expensive city in the world and the most expensive city in the Middle East. In 2014, Dubai's hotel rooms were rated as the second most expensive in the world, after Geneva. Dubai was rated as one of the best places to live in the Middle East by American global consulting firm Mercer.
