"Macau is the gambling capital of the world. Its economy is heavily dependent on gambling and tourism, and in 2006 it surpassed Las Vegas as the world's largest gambling center by revenue. It has a very high Human Development Index and the fourth-highest life expectancy in the world. Macau is among the world's richest regions and its GDP per capita by purchasing power parity was higher than that of any country in the world. In 2015, Macau was ranked as the fastest growing metropolitan area in the world by the Brookings Institution." - Wikipedia
