Macau

Macau^[e] or Macao^[f] is a special administrative region of the People's Republic of China (PRC). With a population of about 710,000 people^[12] and a land area of 32.9 km² (12.7 sq mi), it is the most densely populated region in the world.

Formerly a Portuguese colony, the territory of Portuguese Macau was first leased to Portugal by the Ming dynasty as a trading post in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887, when Portugal gained perpetual colonial rights with the signing of the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until the 1999 handover to China. Macau is a special administrative region of China, which maintains separate governing and economic systems from those of mainland China under the principle of "one country, two systems".^[13] The unique blend of Portuguese and Chinese architecture in the city's historic centre has resulted in its designation as a UNESCO World Heritage Site in 2005.^[14]

The gambling industry of Macau is seven times larger than that of Las Vegas.^[15] The city has one of the highest GDPs per capita and GDPs per capita by purchasing power parity in the world.^[16][17]

It has a very high Human Development Index of 0.934, as calculated by the Government of Macau,^[11] and has the third-highest life expectancy in the world.^[18] The territory is highly urbanised, holding the status of the most densely populated territory on Earth; two-thirds of the total land area is built on land reclaimed from the sea.^[19]
