There are several theories about the origin of the name Dubai. One associates it with the daba—a type of locust that infests the area—while another holds that it refers to a market that existed near the city. In recent years Dubai has been compared to Singapore and Hong Kong and is often regarded as the Middle East’s premier entrepôt. Area 13.5 square miles (35 square km).
