Dubai–Sharjah–Ajman metropolitan area

Dubai–Sharjah–Ajman (DSA) (Arabic: منطقة دبي والشارقة وعجمان الكبرى), is the largest and most densely populated metropolitan area in the United Arab Emirates, located along the central section of the country's coast. It encompasses the contiguous urban territories of the cities of Dubai, Sharjah, and Ajman, forming a singular socio-economic zone governed by three separate emirates.

With a population of 6.3 million, this region is characterized by intense interdependence, high rates of cross-emirate commuting, and shared infrastructure, forming the UAE’s principal urban corridor. The area is also part of a wider conurbation that extends into parts of Umm Al Quwain and western Ras Al Khaimah, though those areas are not included in standard definitions of the DSA core. This metropolitan area represents one of the most densely populated and economically significant regions in the Middle East.
