Roads in Ireland
The island of Ireland, comprising Northern Ireland and the Republic of Ireland, has an extensive network of tens of thousands of kilometres of public roads surfaced. These roads have been developed and modernised over centuries, from trackways suitable only for walkers and horses, to surfaced roads including modern motorways; the major routes were established before Irish independence and take little cognisance of the border other than a change of identification number and street furniture. Northern Ireland has had motorways since 1962, has a well-developed network of primary and local routes; the Republic started work on its motorway network in the early 1980s. However, the Celtic Tiger economic boom and an influx of European Union structural funding, saw national roads and regional roads in the Republic come up to international standard quite quickly. In the mid-1990s, for example, the Republic went from having only a few short sections of motorway to a network of motorways, dual carriageways and other improvements on most major routes as part of a National Development Plan.
Road construction in Northern Ireland now tends to proceed at a slower pace than in the Republic, although a number of important bypasses and upgrades to dual carriageway have been completed or are about to begin. Roads in Northern Ireland are classified as either Highways, motorways, A-roads, B-roads and other roads. There are two types of A-roads: non-primary. Roads in the Republic are classified as either motorways, national roads, regional roads and local roads. There are two types of national roads: national secondary routes. Distance signposts in Northern Ireland show distances in miles, while all signposts placed in the Republic since the 1990s use kilometres; the Republic's road signs are bilingual, using both official languages and English. However, signs in the Gaeltacht use only Irish; the Irish language names are written in the English in capitals. Signs in Northern Ireland are in English only. Warning signs in the Republic have a yellow background and are diamond-shaped, those in Northern Ireland are triangle-shaped and have a white background with a red border.
Speed limits in Northern Ireland are specified in miles per hour. Those in the Republic use kilometres per hour, a change introduced on 20 January 2005; this involved the provision of 58,000 new metric speed limit signs and supplementing 35,000 imperial signs. There have been routes and trackways in Ireland connecting settlements and facilitating trade since ancient times. Ireland was never part of the Roman Empire and, Roman roads were not built in Ireland. However, an Iron Age road with a stone surface has been excavated in Munster and togher roads, a type of causeway built through bogs, were found in many areas of the country. According to an entry in the Annals of the Four Masters for AD 123, there were five principal highways leading to Tara in Early Medieval Ireland. Early medieval law-tracts set out five types of road including the highway, the' main road', the'connecting road', the'side road' which could be tolled, the'cow road'. Bóthar is the most common term for'road' in modern Irish: its diminutive form, bóithrín, is used as a term for narrow, rural roads.
The development of roads in Ireland seemed to have stagnated until the eighteenth- and early nineteenth-centuries. However, in the 18th century, a network of turnpike roads was built: "a turnpike was a primitive form of turnstile – a gate across the road, opened on payment of a toll; the average length of a turnpike road was 30 miles". Routes to and from Dublin were developed and the network spread throughout the country. Turnpikes operated between 1729 and 1858 when the extensive railway network made them unpopular. Specialist routes to facilitate the butter trade, which centred on Cork, were built in Munster; the first butter road was commissioned in 1748 and was built by John Murphy of Castleisland in County Kerry. In other areas, notably in County Wicklow, military roads were built to help secure British military control over remote areas; the Military Road through County Wicklow was begun in 1800 and completed in 1809. The R115 is part of the Military Road for its entire length. Railways became the dominant form of land transport from the mid-19th century.
This situation persisted until the first half of the 20th century when motorised road transport began to take over from railways as the most important form of land transport. Pre-independence legislation laid the foundation for the regulation of the modern system of public roads in Ireland; the Act gave the Minister for Local Government the power to classify roads: Trunk Road Funds were used to enable local councils to improve major roads and road surfacing was undertaken throughout the 1920s, 1930s and beyond. By the 1950s an established system of road classification and numbering with Trunk Roads and Link Roads had long been developed; the present system of road classification and numberi
Baltimore is the largest city in the state of Maryland within the United States. Baltimore was established by the Constitution of Maryland as an independent city in 1729. With a population of 611,648 in 2017, Baltimore is the largest such independent city in the United States; as of 2017, the population of the Baltimore metropolitan area was estimated to be just under 2.808 million, making it the 20th largest metropolitan area in the country. Baltimore is located about 40 miles northeast of Washington, D. C. making it a principal city in the Washington-Baltimore combined statistical area, the fourth-largest CSA in the nation, with a calculated 2017 population of 9,764,315. Baltimore is the second-largest seaport in the Mid-Atlantic; the city's Inner Harbor was once the second leading port of entry for immigrants to the United States. In addition, Baltimore was a major manufacturing center. After a decline in major manufacturing, heavy industry, restructuring of the rail industry, Baltimore has shifted to a service-oriented economy.
Johns Hopkins Hospital and Johns Hopkins University are the city's top two employers. With hundreds of identified districts, Baltimore has been dubbed a "city of neighborhoods." Famous residents have included writers Edgar Allan Poe, Edith Hamilton, Frederick Douglass, Ogden Nash, H. L. Mencken. During the War of 1812, Francis Scott Key wrote "The Star-Spangled Banner" in Baltimore after the bombardment of Fort McHenry, his poem popularized as a song. Baltimore has more public statues and monuments per capita than any other city in the country, is home to some of the earliest National Register Historic Districts in the nation, including Fell's Point, Federal Hill, Mount Vernon; these were added to the National Register between 1969–1971, soon after historic preservation legislation was passed. Nearly one third of the city's buildings are designated as historic in the National Register, more than any other U. S. city. The city has 33 local historic districts. Over 65,000 properties are designated as historic buildings and listed in the NRHP, more than any other U.
S. city. The historical records of the government of Baltimore are located at the Baltimore City Archives; the city is named after Cecil Calvert, second Lord Baltimore of the Irish House of Lords and founding proprietor of the Province of Maryland. Baltimore Manor was the name of the estate in County Longford on which the Calvert family lived in Ireland. Baltimore is an anglicization of the Irish name Baile an Tí Mhóir, meaning "town of the big house." The Baltimore area had been inhabited by Native Americans since at least the 10th millennium BC, when Paleo-Indians first settled in the region. One Paleo-Indian site and several Archaic period and Woodland period archaeological sites have been identified in Baltimore, including four from the Late Woodland period. During the Late Woodland period, the archaeological culture, called the "Potomac Creek complex" resided in the area from Baltimore south to the Rappahannock River in present-day Virginia. In the early 1600s, the immediate Baltimore vicinity was sparsely populated, if at all, by Native Americans.
The Baltimore County area northward was used as hunting grounds by the Susquehannock living in the lower Susquehanna River valley. This Iroquoian-speaking people "controlled all of the upper tributaries of the Chesapeake" but "refrained from much contact with Powhatan in the Potomac region" and south into Virginia. Pressured by the Susquehannock, the Piscataway tribe, an Algonquian-speaking people, stayed well south of the Baltimore area and inhabited the north bank of the Potomac River in what are now Charles and southern Prince George's counties in the coastal areas south of the Fall Line. European colonization of Maryland began with the arrival of an English ship at St. Clement's Island in the Potomac River on March 25, 1634. Europeans began to settle the area further north, beginning to populate the area of Baltimore County; the original county seat, known today as "Old Baltimore", was located on Bush River within the present-day Aberdeen Proving Ground. The colonists engaged in sporadic warfare with the Susquehanna, whose numbers dwindled from new infectious diseases, such as smallpox, endemic among the Europeans.
In 1661 David Jones claimed the area known today as Jonestown on the east bank of the Jones Falls stream. The colonial General Assembly of Maryland created the Port of Baltimore at old Whetstone Point in 1706 for the tobacco trade; the Town of Baltimore, on the west side of the Jones Falls, was founded and laid out on July 30, 1729. By 1752 the town had just 27 homes, including two taverns. Jonestown and Fells Point had been settled to the east; the three settlements, covering 60 acres, became a commercial hub, in 1768 were designated as the county seat. Being a colony, the Baltimore street names were laid out to demonstrate loyalty to the mother country. For example King George, King and Caroline streets. Baltimore grew swiftly in the 18th century, its plantations producing grain and tobacco for sugar-producing colonies in the Caribbean; the profit from sugar encouraged the cultivation of cane in the Caribbean and the importation of food by planters there. As noted, Baltimore was as the county seat, in 1768 a courthouse was built to serve both the city and county.
Its square was a center of community discussions. Baltimore established its public market system in 1763. Lexington Market, founded in 1782, i
A city is a large human settlement. Cities have extensive systems for housing, sanitation, land use, communication, their density facilitates interaction between people, government organizations and businesses, sometimes benefiting different parties in the process. City-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling towards city centers for employment and edification. However, in a world of intensifying globalization, all cities are in different degree connected globally beyond these regions; the most populated city proper is Chongqing while the most populous metropolitan areas are the Greater Tokyo Area, the Shanghai area, Jabodetabek. The cities of Faiyum and Varanasi are among those laying claim to longest continual inhabitation.
A city is distinguished from other human settlements by its great size, but by its functions and its special symbolic status, which may be conferred by a central authority. The term can refer either to the physical streets and buildings of the city or to the collection of people who dwell there, can be used in a general sense to mean urban rather than rural territory. A variety of definitions, invoking population, population density, number of dwellings, economic function, infrastructure, are used in national censuses to classify populations as urban. Common population definitions for a city range between 1,500 and 50,000 people, with most U. S. states using a minimum between 5,000 inhabitants. However, some jurisdictions set no such minimums. In the United Kingdom, city status is awarded by the government and remains permanently, resulting in some small cities, such as Wells and St Davids. According to the "functional definition" a city is not distinguished by size alone, but by the role it plays within a larger political context.
Cities serve as administrative, commercial and cultural hubs for their larger surrounding areas. Examples of settlements called city which may not meet any of the traditional criteria to be named such include Broad Top City and City Dulas, Anglesey, a hamlet; the presence of a literate elite is sometimes included in the definition. A typical city has professional administrators and some form of taxation to support the government workers; the governments may be based on heredity, military power, work projects such as canal building, food distribution, land ownership, commerce, finance, or a combination of these. Societies that live in cities are called civilizations; the word city and the related civilization come, via Old French, from the Latin root civitas meaning citizenship or community member and coming to correspond with urbs, meaning city in a more physical sense. The Roman civitas was linked with the Greek "polis"—another common root appearing in English words such as metropolis. Urban geography deals both with their internal structure.
Town siting has varied through history according to natural, technological and military contexts. Access to water has long been a major factor in city placement and growth, despite exceptions enabled by the advent of rail transport in the nineteenth century, through the present most of the world's urban population lives near the coast or on a river. Urban areas as a rule cannot produce their own food and therefore must develop some relationship with a hinterland which sustains them. Only in special cases such as mining towns which play a vital role in long-distance trade, are cities disconnected from the countryside which feeds them. Thus, centrality within a productive region influences siting, as economic forces would in theory favor the creation of market places in optimal mutually reachable locations; the vast majority of cities have a central area containing buildings with special economic and religious significance. Archaeologists refer to this area by the Greek term temenos; these spaces reflect and amplify the city's centrality and importance to its wider sphere of influence.
Today cities have downtown, sometimes coincident with a central business district. Cities have public spaces where anyone can go; these include owned spaces open to the public as well as forms of public land such as public domain and the commons. Western philosophy since the time of the Greek agora has considered physical public space as the substrate of the symbolic public sphere. Public art adorns public spaces. Parks and other natural sites within cities provide residents with relief from the hardness and regularity of typical built environments. Urban structure follows one or more basic patterns: geomorphic, concentric and curvilinear. Physical environment constrains the form in which a city is built. If located on a mountainside, urban structure may rely on winding roads, it may be adapted to its means of subsistence. And it may be set up for optimal defense given the surrounding landscape. Beyond these "geomorphi
Cleveland is a major city in the U. S. state of Ohio, the county seat of Cuyahoga County. The city proper has a population of 385,525, making it the 51st-largest city in the United States, the second-largest city in Ohio. Greater Cleveland is ranked as the 32nd-largest metropolitan area in the U. S. with 2,055,612 people in 2016. The city anchors the Cleveland–Akron–Canton Combined Statistical Area, which had a population of 3,515,646 in 2010 and is ranked 15th in the United States; the city is located on the southern shore of Lake Erie 60 miles west of the Ohio-Pennsylvania state border. It was founded in 1796 near the mouth of the Cuyahoga River, it became a manufacturing center due to its location on both the river and the lake shore, as well as being connected to numerous canals and railroad lines. Cleveland's economy relies on diversified sectors such as manufacturing, financial services and biomedicals. Cleveland is home to the Rock and Roll Hall of Fame. Cleveland residents are called "Clevelanders".
The city has many nicknames, the oldest of which in contemporary use being "The Forest City". Cleveland was named on July 22, 1796, when surveyors of the Connecticut Land Company laid out Connecticut's Western Reserve into townships and a capital city, they named it "Cleaveland" after General Moses Cleaveland. Cleaveland oversaw design of the plan for what would become the modern downtown area, centered on Public Square, before returning home, never again to visit Ohio; the first settler in Cleaveland was Lorenzo Carter, who built a cabin on the banks of the Cuyahoga River. The Village of Cleaveland was incorporated on December 23, 1814. In spite of the nearby swampy lowlands and harsh winters, its waterfront location proved to be an advantage, giving access to Great Lakes trade; the area began rapid growth after the 1832 completion of the Erie Canal. This key link between the Ohio River and the Great Lakes connected the city to the Atlantic Ocean via the Erie Canal and Hudson River, via the St. Lawrence Seaway.
Its products could reach markets on the Gulf of Mexico via the Mississippi River. Growth continued with added railroad links. Cleveland incorporated as a city in 1836. In 1836, the city located only on the eastern banks of the Cuyahoga River, nearly erupted into open warfare with neighboring Ohio City over a bridge connecting the two. Ohio City remained an independent municipality until its annexation by Cleveland in 1854; the city's prime geographic location as a transportation hub on the Great Lakes has played an important role in its development as a commercial center. Cleveland serves as a destination for iron ore shipped from Minnesota, along with coal transported by rail. In 1870, John D. Rockefeller founded Standard Oil in Cleveland. In 1885, he moved its headquarters to New York City, which had become a center of finance and business. Cleveland emerged in the early 20th century as an important American manufacturing center, its businesses included automotive companies such as Peerless, People's, Jordan and Winton, maker of the first car driven across the U.
S. Other manufacturers located in Cleveland produced steam-powered cars, which included White and Gaeth, as well as the electric car company Baker; because of its significant growth, Cleveland was known as the "Sixth City" of the US during this period. By 1920, due in large part to the city's economic prosperity, Cleveland became the nation's fifth-largest city; the city counted Progressive Era politicians such as the populist Mayor Tom L. Johnson among its leaders, its industrial jobs had attracted waves of European immigrants from southern and eastern Europe, as well as both black and white migrants from the rural South. In commemoration of the centennial of Cleveland's incorporation as a city, the Great Lakes Exposition debuted in June 1936 along the Lake Erie shore north of downtown. Conceived as a way to energize the city after the Great Depression, it drew four million visitors in its first season, seven million by the end of its second and final season in September 1937; the exposition was housed on grounds that are now used by the Great Lakes Science Center, the Rock and Roll Hall of Fame, Burke Lakefront Airport, among others.
Following World War II, Cleveland continued to enjoy a prosperous economy. In sports, the Indians won the 1948 World Series, the hockey team, the Barons, became champions of the American Hockey League, the Browns dominated professional football in the 1950s; as a result, along with track and boxing champions produced, Cleveland was dubbed "City of Champions" in sports at this time. Businesses proclaimed that Cleveland was the "best location in the nation". In 1940, non-Hispanic whites represented 90.2% of Cleveland's population. Wealthy patrons supported development of the city's cultural institutions, such as the art museum and orchestra; the city's population reached its peak of 914,808, in 1949 Cleveland was named an All-America City for the first time. By the 1960s, the economy slowed, residents sought new housing in the suburbs, reflecting the national trends of suburban growth following the subsidized highways. In the 1950s and 1960s, African Americans worked in numerous cities to gain constitutional rights and relief from racial discrimination.
As change lagged despite federal laws to enforce rights and racial unrest occurred in Cleveland and numerous other industrial cities. In Cleveland, the Hough Riots erupted from July 18 to 23, 1966; the Glenville Shootout took place from July 23 to 25, 1968. In November 1967, Cleveland became the first major American city to elect a black mayor, Carl Stokes. Industrial restructuring in the railroad and steel industries, resulted in the loss of numerous
A census is the procedure of systematically acquiring and recording information about the members of a given population. The term is used in connection with national population and housing censuses; the United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory and defined periodicity", recommends that population censuses be taken at least every 10 years. United Nations recommendations cover census topics to be collected, official definitions and other useful information to co-ordinate international practice; the word is of Latin origin: during the Roman Republic, the census was a list that kept track of all adult males fit for military service. The modern census is essential to international comparisons of any kind of statistics, censuses collect data on many attributes of a population, not just how many people there are. Censuses began as the only method of collecting national demographic data, are now part of a larger system of different surveys.
Although population estimates remain an important function of a census, including the geographic distribution of the population, statistics can be produced about combinations of attributes e.g. education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with the same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population. Modern census data are used for research, business marketing, planning, as a baseline for designing sample surveys by providing a sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling. Stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion the number of elected representatives to regions.
In many cases, a chosen random sample can provide more accurate information than attempts to get a population census. A census is construed as the opposite of a sample as its intent is to count everyone in a population rather than a fraction. However, population censuses rely on a sampling frame to count the population; this is the only way to be sure that everyone has been included as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known and a new estimate is to be made by the analysis of primary data; the use of a sampling frame is counterintuitive as it suggests that the population size is known. However, a census is used to collect attribute data on the individuals in the nation; this process of sampling marks the difference between historical census, a house to house process or the product of an imperial decree, the modern statistical project. The sampling frame used by census is always an address register.
Thus it is not known how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed; as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain a number of independent households. A particular problem is what are termed'communal establishments' which category includes student residences, religious orders, homes for the elderly, people in prisons etc; as these are not enumerated by a single householder, they are treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are counted within households and information is collected about the household structure and the housing. For this reason international documents refer to censuses of housing.
The census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted from which cannot be counted. Broadly, three definitions can be used: de facto residence; this is important to consider individuals who have temporary addresses. Every person should be identified uniquely as resident in one place but where they happen to be on Census Day, their de facto residence, may not be the best place to count them. Where an individual uses services may be more useful and this is at their usual, or de jure, residence. An individual may be represented at a permanent address a family home for students or long term migrants, it is necessary to have a precise definition of residence to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems of enumeration are new born babies, people away on holiday, people moving home around census day, people without a fixed address.
People having second homes because of working in another part of the country or retaining a holiday cottage are dif
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.
By the terms of the 1768 Treaty of
New York City
The City of New York called either New York City or New York, is the most populous city in the United States. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles, New York is the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural and media capital of the world, exerts a significant impact upon commerce, research, education, tourism, art and sports; the city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of, a separate county of the State of New York. The five boroughs – Brooklyn, Manhattan, The Bronx, Staten Island – were consolidated into a single city in 1898; the city and its metropolitan area constitute the premier gateway for legal immigration to the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. New York City is home to more than 3.2 million residents born outside the United States, the largest foreign-born population of any city in the world. In 2017, the New York metropolitan area produced a gross metropolitan product of US$1.73 trillion. If greater New York City were a sovereign state, it would have the 12th highest GDP in the world. New York is home to the highest number of billionaires of any city in the world. New York City traces its origins to a trading post founded by colonists from the Dutch Republic in 1624 on Lower Manhattan.
The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, the Duke of York. New York served as the capital of the United States from 1785 until 1790, it has been the country's largest city since 1790. The Statue of Liberty greeted millions of immigrants as they came to the U. S. by ship in the late 19th and early 20th centuries and is an international symbol of the U. S. and its ideals of liberty and peace. In the 21st century, New York has emerged as a global node of creativity and entrepreneurship, social tolerance, environmental sustainability, as a symbol of freedom and cultural diversity. Many districts and landmarks in New York City are well known, with the city having three of the world's ten most visited tourist attractions in 2013 and receiving a record 62.8 million tourists in 2017. Several sources have ranked New York the most photographed city in the world. Times Square, iconic as the world's "heart" and its "Crossroads", is the brightly illuminated hub of the Broadway Theater District, one of the world's busiest pedestrian intersections, a major center of the world's entertainment industry.
The names of many of the city's landmarks and parks are known around the world. Manhattan's real estate market is among the most expensive in the world. New York is home to the largest ethnic Chinese population outside of Asia, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is the largest single-operator rapid transit system worldwide, with 472 rail stations. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, Rockefeller University, which have been ranked among the top universities in the world. Anchored by Wall Street in the Financial District of Lower Manhattan, New York has been called both the most economically powerful city and the leading financial center of the world, the city is home to the world's two largest stock exchanges by total market capitalization, the New York Stock Exchange and NASDAQ. In 1664, the city was named in honor of the Duke of York.
James's older brother, King Charles II, had appointed the Duke proprietor of the former territory of New Netherland, including the city of New Amsterdam, which England had seized from the Dutch. During the Wisconsinan glaciation, 75,000 to 11,000 years ago, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth; the erosive forward movement of the ice contributed to the separation of what is now Long Island and Staten Island. That action left bedrock at a shallow depth, providing a solid foundation for most of Manhattan's skyscrapers. In the precolonial era, the area of present-day New York City was inhabited by Algonquian Native Americans, including the Lenape, whose homeland, known as Lenapehoking, included Staten Island; the first documented visit into New York Harbor by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown. He named it Nouvelle Angoulême. A Spanish expedition led by captain Estêvão Gomes, a Portuguese sailing for Emperor Charles V, arrived in New York Harbor in January 1525 and charted the mouth of the Hudson River, which he named Río de San Antonio.
