Which city is the most populous in the United Arab Emirates?

Dubai is the most populous city in the United Arab Emirates (UAE) and the capital of the Emirate of Dubai.

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. Today, less than 5% of the emirate's revenue comes from oil. 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.

As of September 2019, the population is 3,331,420 – an annual increase of 177,020 people which represents a growth rate of 5.64%. The region covers 1,287.5 square kilometres (497.1 sq mi). The population density is 408.18/km2 – more than eight times that of the entire country. Dubai is the second most expensive city in the region and 20th most expensive city in the world.
