Dubai

The largest city in the United Arab Emirates, Dubai has expanded by 300% over the past 20 years, establishing itself as one of the world's wealthiest cities as a result of the nation's large oil reserves. The growth in Dubai has been so rapid, that the government occasionally stops issuing addresses to new buildings and developments, as the construction and expansion of the city has been outpacing the government's ability to issue addresses for the past 10 years.
