Macau vs Pittsburgh

Informations

Macau ( (listen); 澳門, Cantonese: [ōu.mǔːn]; Portuguese: [mɐˈkaw]), also spelled Macao and officially the Macao Special Administrative Region of the People's Republic of China, is a city and special administrative region of the People's Republic of China in the western Pearl River Delta by the South China Sea. With a population of about 650,000 and an area of 32.9 km2 (12.7 sq mi), it is the most densely populated region in the world. Macau is a former colony of the Portuguese Empire, after Ming China leased the territory as a trading post in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887, when it gained perpetual colonial rights in the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until 1999, when it was transferred 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".

Originally a sparsely populated collection of coastal islands, the territory has become a major resort city and a top destination for gambling tourism, with a gambling industry seven times larger than that of Las Vegas. The city has one of the highest per capita incomes in the world, and its GDP per capita by purchasing power parity is one of the highest in the world; however, income inequality remains high. It has a very high Human Development Index, as calculated by the Macau government, and the fourth-highest life expectancy in the world. The territory is highly urbanised and most development is built on reclaimed land; two-thirds of the total land area is reclaimed from the sea.

Pittsburgh ( PITS-burg) is a city in the state of Pennsylvania in the United States, and is the county seat of Allegheny County. A population of about 300,286 (2019) residents live within the city limits, making it the 66th-largest city in the U.S. and the second-most populous city in Pennsylvania behind Philadelphia. The Pittsburgh metropolitan area is the anchor of Western Pennsylvania; its population of 2,324,743 is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania, and the 27th-largest in the U.S. Pittsburgh is located in the southwest of the state, at the confluence of the Allegheny River and the Monongahela River, forming the Ohio River. Pittsburgh is known both as "the Steel City" for its more than 300 steel-related businesses and as the "City of Bridges" for its 446 bridges. The city features 30 skyscrapers, two inclined railways, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains made the area coveted by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders.Aside from steel, Pittsburgh has led in the manufacturing of other important materials — aluminum and glass — and in the petroleum industry. Additionally, it is a leader in computing, electronics, and the automotive industry. For part of the 20th century, Pittsburgh was behind only New York City and Chicago in corporate headquarters employment; it had the most U.S. stockholders per capita. Deindustrialization in the 1970s and 80s laid off area blue-collar workers as steel and other heavy industries declined, and thousands of downtown white-collar workers also lost jobs when several Pittsburgh-based companies moved out.

The population dropped from a peak of 675,000 in 1950 to 370,000 in 1990. However, this rich industrial history left the area with renowned museums, medical centers, parks, research centers, and a diverse cultural district.After the deindustrialization of the mid-20th century, Pittsburgh has transformed into a hub for the health care, education, and technology industries. Pittsburgh is a leader in the health care sector as the home to large medical providers such as University of Pittsburgh Medical Center (UPMC). The area is home to 68 colleges and universities, including research and development leaders Carnegie Mellon University and the University of Pittsburgh. Google, Apple Inc., Bosch, Facebook, Uber, Nokia, Autodesk, Amazon, Microsoft and IBM are among 1,600 technology firms generating $20.7 billion in annual Pittsburgh payrolls. The area has served as the long-time federal agency headquarters for cyber defense, software engineering, robotics, energy research and the nuclear navy. The nation's eighth-largest bank, eight Fortune 500 companies, and six of the top 300 U.S. law firms make their global headquarters in the area, while RAND Corporation (RAND), BNY Mellon, Nova, FedEx, Bayer, and the National Institute for Occupational Safety and Health (NIOSH) have regional bases that helped Pittsburgh become the sixth-best area for U.S. job growth.In 2015, Pittsburgh was listed among the "eleven most livable cities in the world"; The Economist's Global Liveability Ranking placed Pittsburgh as the most or second-most livable city in the United States in 2005, 2009, 2011, 2012 and 2014. The region is a hub for Leadership in Energy and Environmental Design and energy extraction.
