Located in the eastern part of the Arabian Peninsula on the coast of the Persian Gulf, Dubai aims to be the business hub of Western Asia. It is also a major global transport hub for passengers and cargo. Oil revenue helped accelerate the development of the city, which was already a major mercantile hub. A centre for regional and international trade since the early 20th century, Dubai’s economy relies on revenues from trade, tourism, aviation, real estate, and financial services. Oil production contributed less than 1 percent of the emirate’s GDP in 2018. The city has a population of around 2.9 million (as of 2017).
