Essen vs Pittsburgh

Informations

Essen (German pronunciation: [ˈɛsn̩] (listen); Latin: Assindia) is the central and second largest city of the Ruhr, the largest urban area in Germany. Its population of 583,109 makes it the ninth largest city of Germany, as well as the fourth largest city of the federal state of North Rhine-Westphalia. On the Ruhr and Emscher rivers, Essen geographically is part of the Rhineland and the larger Rhine-Ruhr Metropolitan Region. The Ruhrdeutsch regiolect spoken in the region has strong influences of both Low German (Westphalian) and Low Franconian (East Bergish). Essen is seat to several of the region's authorities, as well as to eight of the 100 largest publicly held German corporations by revenue, including two DAX corporations. Essen is often considered the energy capital of Germany with E.ON and RWE, Germany's largest energy providers, both headquartered in the city. Essen is also known for its impact on the arts through the respected Folkwang University of the Arts, its Zollverein School of Management and Design, and the Red Dot industrial product design award. In early 2003, the universities of Essen and the nearby city of Duisburg (both established in 1972) were merged into the University of Duisburg-Essen with campuses in both cities and a university hospital in Essen. In 1958, Essen was chosen to serve as the seat to a Roman Catholic diocese (often referred to as Ruhrbistum or diocese of the Ruhr).

Founded around 845, Essen remained a small town within the sphere of influence of an important ecclesiastical principality (Essen Abbey) until the onset of industrialization. The city then — especially through the Krupp family iron works — became one of Germany's most important coal and steel centers. Essen, until the 1970s, attracted workers from all over the country; it was the 5th-largest city in Germany between 1929 and 1988, peaking at over 730,000 inhabitants in 1962. Following the region-wide decline of heavy industries in the last decades of the 20th century, the city has seen the development of a strong tertiary sector of the economy. The most notable witness of this Strukturwandel (structural change) is the Zollverein Coal Mine Industrial Complex, which has once been the largest of its kind in Europe. Ultimately closed in 1993, both the coking plant and the mine have been inscribed in the list of UNESCO World Heritage Sites since 2001. Notable accomplishments of the city in recent years include the title of European Capital of Culture on behalf of the whole Ruhr area in 2010 and the selection as the European Green Capital for 2017.

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.
