Pittsburgh is a city in the Commonwealth of Pennsylvania in the United States, is the county seat of Allegheny County. As of 2018, a population of 308,144 lives within the city limits, making it the 63rd-largest city in the U. S; the metropolitan population of 2,362,453, is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania, the 26th-largest in the U. S. Pittsburgh is located in the south west of the state, at the confluence of the Allegheny 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, Whiskey Rebels, Civil War raiders. Aside from steel, Pittsburgh has led in manufacturing of aluminum, shipbuilding, foods, transportation, computing and electronics.
For part of the 20th century, Pittsburgh was behind only New York and Chicago in corporate headquarters employment. S. stockholders per capita. America's 1980s deindustrialization laid off area blue-collar workers and thousands of downtown white-collar workers when the longtime Pittsburgh-based world headquarters moved out; this heritage left the area with renowned museums, medical centers, research centers, a diverse cultural district. Today, Apple Inc. Bosch, Uber, Autodesk, 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, energy research and the nuclear navy; the area is home to 68 colleges and universities, including research and development leaders Carnegie Mellon University and the University of Pittsburgh. The nation's eighth-largest bank, eight Fortune 500 companies, six of the top 300 U. S. law firms make their global headquarters in the area, while RAND, BNY Mellon, FedEx, Bayer and 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 region is a hub for Environmental Design and energy extraction. In 2019, Pittsburgh was deemed “Food City of the Year” by the San Francisco-based restaurant and hospitality consulting firm af&co. Many restaurants were mentioned favorable, among them were Superior Motors in Braddock, Driftwood Oven in Lawrenceville, Spork in Bloomfield, Fish nor Fowl in Garfield and Bitter Ends Garden & Luncheonette in Bloomfield. Pittsburgh was named in 1758 by General John Forbes, in honor of British statesman William Pitt, 1st Earl of Chatham; as Forbes was a Scot, he pronounced the name PITS-bər-ə. Pittsburgh was incorporated as a borough on April 22, 1794, with the following Act: "Be it enacted by the Pennsylvania State Senate and Pennsylvania House of Representatives of the Commonwealth of Pennsylvania... by the authority of the same, that the said town of Pittsburgh shall be... erected into a borough, which shall be called the borough of Pittsburgh for ever."
From 1891 to 1911, the city's name was federally recognized as "Pittsburg", though use of the final h was retained during this period by the city government and other local organizations. After a public campaign, the federal decision to drop the h was reversed; the area of the Ohio headwaters was long inhabited by the Shawnee and several other settled groups of Native Americans. The first known European to enter the region was the French explorer/trader Robert de La Salle from Quebec during his 1669 expedition down the Ohio River. European pioneers Dutch, followed in the early 18th century. Michael Bezallion was the first to describe the forks of the Ohio in a 1717 manuscript, that year European fur traders established area posts and settlements. In 1749, French soldiers from Quebec launched an expedition to the forks to unite Canada with French Louisiana via the rivers. During 1753–54, the British hastily built Fort Prince George before a larger French force drove them off; the French built Fort Duquesne based on LaSalle's 1669 claims.
The French and Indian War, the North American front of the Seven Years' War, began with the future Pittsburgh as its center. British General Edward Braddock was dispatched with Major George Washington as his aide to take Fort Duquesne; the British and colonial force were defeated at Braddock's Field. General John Forbes took the forks in 1758. Forbes began construction on Fort Pitt, named after William Pitt the Elder while the settlement was named "Pittsborough". During Pontiac's Rebellion, native tribes conducted a siege of Fort Pitt for two months until Colonel Henry Bouquet relieved it after the Battle of Bushy Run. Fort Pitt is notable as the site of an early use of smallpox for biological warfare. Lord Jeffery Amherst ordered blankets contaminated from smallpox victims to be distributed in 1763 to the tribes surrounding the fort; the disease spread into other areas, infected other tribes, killed hundreds of thousands. During this period, the powerful nations of the Iroquois Confederacy, based in New York, had maintained control of much of the Ohio Valley as hunting grounds by right of conquest after defeating other tribes.

1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.

Mount Oliver, Pennsylvania
Mount Oliver is a borough in Allegheny County, United States. It is a residential area situated atop a crest about 3 miles west of the Monongahela River; the borough is surrounded by the city of Pittsburgh, having resisted annexations by the city, as it prefers to manage its own local needs and finances. It is named for Oliver Ormsby, son of John Ormsby, who held the original land grant for the area from George III.

2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

South Side Slopes, Pittsburgh
South Side Slopes is a neighborhood in Pittsburgh, Pennsylvania's South Side area. The neighborhood comprises the hills from the South Side Flats neighborhood along the Monongahela River from the Liberty Bridge to beyond Josephine Street. In many parts of the South Side Slopes, homes offer panoramic views of the city skyline that span the distance from beyond McKees Rocks, PA to Homestead, PA. Many homes are perched well above the city skyline; this neighborhood provides access to the South Side Flats by various means including the many public staircases. Every autumn the South Side Slopes Neighborhood Association hosts its annual "StepTrek", where participants travel over the various public step streets. Pittsburgh, like many cities in the United States built on hillsides, classifies public staircases as streets; the hills being steep, staircases allowed access to the different parts of the slopes neighborhood. The SSSNA hopes to maintain the staircases as a legacy of its history as a mining town.
The Mission Street steps between Oakley Street and Barry Street in addition to the top of Yard Way off Pius St. offer views of the South Side Flats neighborhood and downtown Pittsburgh. These public staircases are sometimes called paper streets, being pedestrian streets shown on City maps but not accessible by vehicles; the neighborhood has representation on the Pittsburgh City Council by the council member for District 3. The Pittsburgh Bureau of Fire houses 24 Engine and 24 Truck on the South Side, it is located on Mary Street just off of Carson Street. The South Side Slopes area is served by Engine Co 22, located in the neighborhood on Arlington Avenue adjoining South Side Park. South Side Park is a City Park with hiking trails, a small orchard patch and views of the City of Pittsburgh skyline, it is home to many species of small animals and deer. It contains a small wetlands area, complete with many species of wildlife. Black locust trees form a mature canopy over the park, it includes a community garden at the former Bandi Schaum baseball field on the lower plateau off Mission Street across from the Mission Street water pumping station.
Several times each summer, college groups gather en masse, start a bonfire on the bluff, get loudly wasted. Neighbors always notify the authorities and the fire department and police show up and chase the revelers away - once. July 4 is another thing entirely. Amateur fireworks for several days at random hours. Other than that, the park is a green oasis in a landscape of metal and red brick. A cor-ten sculpture representing the neighborhood's topography and buildings is on display in the garden of Paul of the Cross Monastery. In 1763, King George III of England granted John Ormsby, a soldier in the French and Indian War as well as the alleged first settler of Pittsburgh, 2,400 acres of land along the southern banks of the Monongahela River for his service in the capture of Fort Duquesne. Ormsby divided the land into four boroughs - South Pittsburgh, Birmingham and East Birmingham, present day South Side Slopes. South Side expanded and grew in order to keep up with Pittsburgh's industrial boom, adopting the nickname "Workshop of the World".
The industry of glass-making was predominant in the early 1800s, the banks of the Monongahela River became home to the iron and steel operations run by the company J&L Steel. J&L became South Side's largest employer as by 1910 it employed 15,000 workers; the majority of these workers came as immigrants from European nations such as Germany, Poland, the Ukraine, the Slavic nations and settled into homes in the present day South Side Slopes. The houses built for them were traditionally one room wide, two rooms deep, up to four stories high; the houses are built into the hillside with narrow walkways between them. Most of the structures and houses in both South Side Slopes are balloon-framed whereas many of those on the South Side Flats were built from brick, in a rectangular fashion. Many of them were ornamented in the popular style of the 1900s - Romanesque and Second Empire, they are fashioned in a classical Victorian style row home way with carved doorways, corbelling, cast iron ornaments and geometric slate patterns.
The Slopes is rich in culture as many immigrants wanted to preserve their native cultures and languages. South Side Slopes is located at 40.42 N and 79.97 W. The area South Side Slopes covers is 0.716 square miles or 460.632 acres. It is made up of many slopes with elevations ranging from 791 feet to 1,174 feet. There are some areas that are too steep for automobile navigation so the numerous staircases located throughout South Side Slopes serve as the "streets". There have been 70 sets of staircases found in the neighborhood. South Side Slopes is part of District 3 in Allegheny County. 18th Street, Arlington Avenue, Josephine Street are two of the main roads that run through the neighborhood. It is 2.8 miles from the Monongahela River and the historic Birmingham Bridge. The Slopes neighborhood is close to the diverse East Carson Street and the SouthSide Works shopping center. South Side Slopes has an overall cold climate, meaning it has about 5,400 heating degree days and fewer than 9,000 heating degree days based on a temperature of 65 degrees Fahrenheit.
It can experience temperatures that range from 90 degrees Fahrenheit to negative 10 degrees Fahrenheit. The area accumulates an average of 30 to 40 inches of precipitation per year. Allegheny County can get anywhere from zero to twenty inches of snow per month during th
Allegheny County, Pennsylvania
Allegheny County is a county in the southwest of the U. S. state of Pennsylvania. As of 2017 the population was 1,223,048, making it the state's second-most populous county, following Philadelphia County; the county seat is Pittsburgh. Allegheny County is included in the Pittsburgh, PA Metropolitan Statistical Area, in the Pittsburgh Designated Market Area. Allegheny was Pennsylvania's first to bear a Native American name, being named after the Allegheny River; the word "Allegheny" is with uncertain meaning. It is said to mean "fine river", but sometimes said to refer to an ancient mythical tribe called "Allegewi" that lived along the river before being destroyed by the Lenape. Little is known of the region's inhabitants prior to European contact. During the colonial era, various native groups claimed or settled in the area, resulting in a multi-ethnic mix that included Iroquois, Lenape and Mingo. European fur traders such as Peter Chartier established trading posts in the region in the early eighteenth century.
In 1749, Captain Pierre Joseph Céloron de Blainville claimed the Ohio Valley and all of western Pennsylvania for Louis XV of France. The captain traveled along the Ohio and Allegheny rivers inserting lead plates in the ground to mark the land for France. Since most of the towns during that era were developed along waterways, both the French and the British desired control over the local rivers. Therefore, the British sent Major George Washington to expel the French from their posts, with no success. Failing in this objective, he nearly drowned in the ice-filled Allegheny River while returning; the English tried in 1754 to again enter the area. They sent 41 Virginians to build Fort Prince George; the French learned of the plan and sent an army to capture the fort, which they resumed building with increased fortification, renaming it Fort Duquesne. The loss cost the English dearly because Fort Duquesne became a focal point of the French and Indian War; the first attempt to retake the fort, the Braddock Expedition, failed miserably.
It was recaptured in 1758 by British forces under General John Forbes. The British built a new, larger fort on the site, including a moat, named it Fort Pitt; the site is now Pittsburgh's Point State Park. Both Pennsylvania and Virginia claimed the region, now Allegheny County. Pennsylvania administered most of the region as part of its Westmoreland County. Virginia considered everything south of the Ohio River and east of the Allegheny River to be part of its Yohogania County and governed it from Fort Dunmore. In addition, parts of the county were located in the proposed British colony of Vandalia and the proposed U. S. state of Westsylvania. The overlapping boundaries, multiple governments, confused deed claims soon proved unworkable. In 1780 Pennsylvania and Virginia agreed to extend the Mason–Dixon line westward, the region became part of Pennsylvania. From 1781 until 1788, much of what had been claimed as part of Yohogania County, was administered as a part of the newly created Washington County, Pennsylvania.
Allegheny County was created on September 24, 1788, from parts of Washington and Westmoreland counties. It was formed due to pressure from settlers living in the area around Pittsburgh, which became the county seat in 1791; the county extended north to the shores of Lake Erie. In the 1790s, a whiskey excise tax was imposed by the United States federal government; this started the so-called Whiskey Rebellion when the farmers who depended on whiskey income refused to pay and drove off tax collector John Neville. After a series of demonstrations by farmers, President George Washington sent troops to stop the rebellion; the area developed in the 1800s to become the nation's prime steel producer. In 1913 the County's 125th anniversary was celebrated with a week long chain of events, the final day September 27 was marked with a steamboat parade consisting of 30 paddle wheelers which sailed from Monongahela Wharf down the Ohio to the Davis Island Dam; the boats in line were the flag ship.

Census Bureau, the county has a total area of 745 square miles, of which 730 square miles is land and 14 square miles is water. Three majors traverse Allegheny County: the Allegheny River and the Monongahela River converge at Downtown Pittsburgh to form the Ohio River; the Youghiogheny River flows into the Monongahela River at McKeesport, 10 miles southeast. There are several islands in these courses; the rivers drain into the Gulf of Mexico via the Mississippi River. Although the county's industrial growth caused the clearcutting of the area's forests, a significant woodland remains. Butler County Armstrong County Beaver County Westmoreland County Washington County Until January 1, 2000, Allegheny County's government was defined under Pennsylvania's Second Class County Code; the county government was charged with all local activities, including elections, airports, public health, city planning.
All public offices were headed by elected citizens. There were three elected county commissioners. On January 1, 2000 the Home-Rule Charter went into effect, it replaced the three elected commissioners wi
