Pittsburgh vs Odesa

Informations

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, Monongahela, and Ohio rivers. 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, glass and petroleum. 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.

Odessa or Odesa (Ukrainian: Оде́са, romanized: Odesa [oˈdɛsɐ] (listen); Russian: Оде́сса, romanized: Odessa [ɐˈdʲesə]; Bulgarian: Оде́са, romanized: Odesa) is the third most populous city of Ukraine and a major tourism center, seaport and transport hub located on the northwestern shore of the Black Sea. It is also the administrative center of the Odessa Oblast and a multiethnic cultural center. Odessa is sometimes called the "pearl of the Black Sea", the "South Capital" (under the Russian Empire and Soviet Union), and "Southern Palmyra". Before the Tsarist establishment of Odessa, an ancient Greek settlement existed at its location. A more recent Tatar settlement was also founded at the location by Hacı I Giray, the Khan of Crimea in 1440 that was named after him as Hacibey (or Khadjibey). After a period of Lithuanian Grand Duchy control, Hacibey and surroundings became part of the domain of the Ottomans in 1529 and remained there until the empire's defeat in the Russo-Turkish War of 1792. In 1794, the city of Odessa was founded by a decree of the Russian empress Catherine the Great. From 1819 to 1858, Odessa was a free port—a porto-franco.

During the Soviet period, it was the most important port of trade in the Soviet Union and a Soviet naval base. On 1 January 2000, the Quarantine Pier at Odessa Commercial Sea Port was declared a free port and free economic zone for a period of 25 years. During the 19th century, Odessa was the fourth largest city of Imperial Russia, after Moscow, Saint Petersburg and Warsaw. Its historical architecture has a style more Mediterranean than Russian, having been heavily influenced by French and Italian styles. Some buildings are built in a mixture of different styles, including Art Nouveau, Renaissance and Classicist.Odessa is a warm-water port. The city of Odessa hosts both the Port of Odessa and Port Yuzhne, a significant oil terminal situated in the city's suburbs. Another notable port, Chornomorsk, is located in the same oblast, to the south-west of Odessa. Together they represent a major transport hub integrating with railways. Odessa's oil and chemical processing facilities are connected to Russian and European networks by strategic pipelines. Current population is 1,017,699 (2020 est.)
