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
1890 United States Census
The Eleventh United States Census was taken beginning June 2, 1890. It determined the resident population of the United States to be 62,979,766—an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census. The data was tabulated by machine for the first time; the data reported that the distribution of the population had resulted in the disappearance of the American frontier. Most of the 1890 census materials were destroyed in a 1921 fire and fragments of the US census population schedule exist only for the states of Alabama, Illinois, New Jersey, New York, North Carolina, South Dakota, Texas, the District of Columbia; this was the first census in which a majority of states recorded populations of over one million, as well as the first in which multiple cities – New York as of 1880, Philadelphia – recorded populations of over one million. The census saw Chicago rank as the nation's second-most populous city, a position it would hold until 1990, in which Los Angeles would supplant it.
The 1890 census collected the following information: The 1890 census was the first to be compiled using methods invented by Herman Hollerith and was overseen by Superintendents Robert P. Porter and Carroll D. Wright. Data was entered on a machine readable medium, punched cards, tabulated by machine; the net effect of the many changes from the 1880 census: the larger population, the number of data items to be collected, the Census Bureau headcount, the volume of scheduled publications, the use of Hollerith's electromechanical tabulators, was to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 census. The total population of 62,947,714, the family, or rough, was announced after only six weeks of processing; the public reaction to this tabulation was disbelief, as it was believed that the "right answer" was at least 75,000,000. The United States census of 1890 showed a total of 248,253 Native Americans living in the United States, down from 400,764 Native Americans identified in the census of 1850.
The 1890 census announced that the frontier region of the United States no longer existed, that the Census Bureau would no longer track the westward migration of the U. S. population. Up to and including the 1880 census, the country had a frontier of settlement. By 1890, isolated bodies of settlement had broken into the unsettled area to the extent that there was hardly a frontier line; this prompted Frederick Jackson Turner to develop his Frontier Thesis. The original data for the 1890 Census is no longer available. All the population schedules were damaged in a fire in the basement of the Commerce Building in Washington, D. C. in 1921. Some 25 % of the materials were presumed another 50 % damaged by smoke and water; the damage to the records led to an outcry for a permanent National Archives. In December 1932, following standard federal record-keeping procedures, the Chief Clerk of the Bureau of the Census sent the Librarian of Congress a list of papers to be destroyed, including the original 1890 census schedules.
The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, but the Librarian did not accept the census records. Congress authorized destruction of that list of records on February 21, 1933, the surviving original 1890 census records were destroyed by government order by 1934 or 1935; the other censuses for which some information has been lost are the 1810 enumerations. Few sets of microdata from the 1890 census survive, but aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System.

Augusta Augusta–Richmond County, is a consolidated city-county on the central eastern border of the U. S. state of Georgia. The city lies across the Savannah River from South Carolina at the head of its navigable portion. Georgia's second-largest city after Atlanta, Augusta is located in the Piedmont section of the state. According to the U. S. Census Bureau, Augusta–Richmond County had a 2017 estimated population of 197,166, not counting the unconsolidated cities of Blythe and Hephzibah, it is the 122nd largest city in the United States. The process of consolidation between the City of Augusta and Richmond County began with a 1995 referendum in the two jurisdictions; the merger was completed on July 1, 1996. Augusta is the principal city of the Augusta metropolitan area, situated in both Georgia and South Carolina on both sides of the Savannah River. In 2017 it had an estimated population of 600,151, making it the second-largest metro area in the state, it is the 93rd largest metropolitan area in the United States.
Augusta was established in 1736 and is named for Princess Augusta of Saxe-Gotha, the bride of Frederick, Prince of Wales and the mother of the British monarch George III. During the American Civil War, Augusta housed the principal Confederate powder works. Augusta's warm climate made it a major resort town of the Eastern United States in the early and mid-20th century. Internationally, Augusta is best known for hosting The Masters golf tournament each spring; the Masters brings over 200,000 visitors from across the world to the Augusta National Golf Club. Membership at Augusta National is considered to be the most exclusive in the sport of golf across the world. Augusta lies two hours east of downtown Atlanta by car via I-20; the city is home to Fort Gordon, a major U. S. Army base. In 2016, it was announced that the new National Cyber Security Headquarters would be based in Augusta, bringing as many as 10,000 cyber security specialists to the Fort Gordon area; the area along the river was long inhabited by varying cultures of indigenous peoples, who relied on the river for fish and transportation.
The site of Augusta was used by Native Americans as a place to cross the Savannah River, because of its location on the fall line. In 1735, two years after James Oglethorpe founded Savannah, he sent a detachment of troops to explore the upper Savannah River, he gave them an order to build a fort at the head of the navigable part of the river. The expedition was led by Noble Jones, who created a settlement as a first line of defense for coastal areas against potential Spanish or French invasion from the interior. Oglethorpe named the town in honor of Princess Augusta, the mother of King George III and the wife of Frederick, Prince of Wales. Oglethorpe visited Augusta in September 1739 on his return to Savannah from a perilous visit to Coweta Town, near present-day Phenix City, Alabama. There, he had met with a convention of 7,000 Native American warriors and concluded a peace treaty with them in their territories in northern and western Georgia. Augusta was the second state capital of Georgia from 1785 until 1795.
Augusta developed as a market town as the Black Belt in the Piedmont was developed for cotton cultivation. Invention of the cotton gin made processing of short-staple cotton profitable, this type of cotton was well-suited to the upland areas. Cotton plantations were worked by slave labor, with hundreds of thousands of slaves shipped from the Upper South to the Deep South in the domestic slave trade. Many of the slaves were brought from the Lowcountry, where their Gullah culture had developed on the large Sea Island cotton and rice plantations; the city experienced the Augusta Fire of 1916, which damaged 25 blocks of the town and many buildings of historical significance. As a major city in the area, Augusta was a center of activities after. In the mid-20th century, it was a site of civil rights demonstrations. In 1970 Charles Oatman, a mentally disabled teenager, was killed by his cellmates in an Augusta jail. A protest against his death broke out in a riot involving 500 people, after six black men were killed by police, each found to have been shot in the back.
The noted singer and entertainer James Brown was called in to help quell lingering tensions, which he succeeded in doing. Augusta is located on the Georgia/South Carolina border, about 150 miles east of Atlanta and 70 miles west of Columbia; the city is located at 33°28′12″N 81°58′30″W. According to the United States Census Bureau, the Augusta–Richmond County balance has a total area of 306.5 square miles, of which 302.1 square miles is land and 4.3 square miles is water. Augusta is located about halfway up the Savannah River on the fall line, which creates a number of small falls on the river; the city marks the end of a navigable waterway for the river and the entry to the Georgia Piedmont area. The Clarks Hill Dam is built on the fall line near Augusta. Farther downstream, near the border of Columbia County, is the Stevens Creek Dam, which generates hydroelectric power. Farther downstream is the Augusta Diversion Dam, which marks the beginning of the Augusta Canal and channels Savannah River waters into the canal.
As with the rest of the state, Augusta has a humid subtropical climate, with short, mild winters hot, humid summers, a wide diurnal temperature variation throughout much of the year, despite its low elevation and moisture. The monthly daily average temperature ranges from 45.4 °F in January to 81.6 °F in July.
A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in Canada, Romania and the United States. County towns have a similar function in the United Kingdom and Republic of Ireland, in Jamaica. In most of the United States, counties are the political subdivisions of a state; the city, town, or populated place that houses county government is known as the seat of its respective county. The county legislature, county courthouse, sheriff's department headquarters, hall of records and correctional facility are located in the county seat though some functions may be located or conducted in other parts of the county if it is geographically large. A county seat is but not always, an incorporated municipality; the exceptions include the county seats of counties that have no incorporated municipalities within their borders, such as Arlington County, Virginia. Ellicott City, the county seat of Howard County, is the largest unincorporated county seat in the United States, followed by Towson, the county seat of Baltimore County, Maryland.
Some county seats may not be incorporated in their own right, but are located within incorporated municipalities. For example, Cape May Court House, New Jersey, though unincorporated, is a section of Middle Township, an incorporated municipality. In some of the colonial states, county seats include or included "Court House" as part of their name. In the Canadian provinces of Prince Edward Island, New Brunswick, Nova Scotia, the term "shire town" is used in place of county seat. County seats in Taiwan are the administrative centers of the counties. There are 13 county seats in Taiwan, which are in the forms of county-administered city, urban township or rural township. Most counties have only one county seat. However, some counties in Alabama, Georgia, Kentucky, Mississippi, New Hampshire, New York, Vermont have two or more county seats located on opposite sides of the county. An example is Harrison County, which lists both Biloxi and Gulfport as county seats; the practice of multiple county seat towns dates from the days.
There have been few efforts to eliminate the two-seat arrangement, since a county seat is a source of pride for the towns involved. There are 36 counties with multiple county seats in 11 states: Coffee County, Alabama St. Clair County, Alabama Arkansas County, Arkansas Carroll County, Arkansas Clay County, Arkansas Craighead County, Arkansas Franklin County, Arkansas Logan County, Arkansas Mississippi County, Arkansas Prairie County, Arkansas Sebastian County, Arkansas Yell County, Arkansas Columbia County, Georgia Lee County, Iowa Campbell County, Kentucky Kenton County, Kentucky Essex County, Massachusetts Middlesex County, Massachusetts Plymouth County, Massachusetts Bolivar County, Mississippi Carroll County, Mississippi Chickasaw County, Mississippi Harrison County, Mississippi Hinds County, Mississippi Jasper County, Mississippi Jones County, Mississippi Panola County, Mississippi Tallahatchie County, Mississippi Yalobusha County, Mississippi Jackson County, Missouri Hillsborough County, New Hampshire Seneca County, New York Bennington County, Vermont In New England, the town, not the county, is the primary division of local government.
Counties in this region have served as dividing lines for the states' judicial systems. Connecticut and Rhode Island have no county level of thus no county seats. In Vermont and Maine the county seats are designated shire towns. County government consists only of a Superior Court and Sheriff, both located in the respective shire town. Bennington County has two shire towns. In Massachusetts, most government functions which would otherwise be performed by county governments in other states are performed by town or city governments; as such, Massachusetts has dissolved many of its county governments, the state government now operates the registries of deeds and sheriff's offices in those counties. In Virginia, a county seat may be an independent city surrounded by, but not part of, the county of which it is the administrative center. Two counties in South Dakota have their county seat and government services centered in a neighboring county, their county-level services are provided by Fall River Tripp County, respectively.
In Louisiana, divided into parishes rather than counties, county seats are referred to as parish seats. Alaska is divided into boroughs rather than counties; the Unorganized Borough, which covers 49 % of Alaska's area, has equivalent. The state with the most counties is Texas, with 254, the state with the fewest counties is Delaware, with 3.

Hamburg, Aiken County, South Carolina
The ghost town of Hamburg, South Carolina, was once a thriving upriver market located in Edgefield District of the Piedmont. It was founded by Henry Shultz in 1821, across the Savannah River from Augusta, Georgia, in direct competition with that city. In its heyday, 60,000 bales of cotton worth $2,000,000 were brought by wagon to Hamburg each year; this cotton continued by pole boat or steam boat to the ports of Charleston or Savannah for subsequent shipment to manufacturers in New England or Europe. Hamburg lost business after Augusta completed its canal in 1848. After the American Civil War, Hamburg was repopulated by freedmen and was within newly organized Aiken County, it became notorious in July 1876 as the site of a massacre of blacks by whites in what was one of a number of violent incidents by Democratic paramilitary groups to suppress black voting in that year's elections. The Democrats regained control of the state government and federal troops were withdrawn the next year from South Carolina and other states, ending the Reconstruction era.
During his American tour as'Guest of the Nation', the Marquis de Lafayette visited Hamburg on March 24, 1825. The town became the western terminus of the South Carolina Railroad; this was the world's first railroad in the modern pattern. Providing scheduled steam service over 136 miles of line from Charleston to Hamburg, it was the world's longest at its completion in 1833. A railroad bridge was constructed over the Savannah River in 1854 but Hamburg was in decline. With completion of the Augusta Canal and general expansion of railroads in the 1850s, strenuous overland hauls to Hamburg became unnecessary and the famous wagon traffic declined. Hamburg became a ghost town by the time of the Civil War. Following the war, Hamburg was governed by freedmen, starting with Prince Rivers; these three men were founders of Aiken County. They began attracting freedmen. To celebrate Aiken County's 125th anniversary, a stone-and-bronze marker was installed at the county courthouse. Rivers and Leeld are listed as founders but their race is not indicated.
After the deaths and damage in the Hamburg Massacre of July 8, 1876, the town declined for good. Augusta began construction of a river levee after a 1911 flood. Disastrous floods forced out the last residents in 1929. Styled as Hamburgh, the town was named after Shultz's home town in Germany, it was located at 33.4799 ° N, 81.9579 ° W directly across the Savannah River from Georgia. Population at its peak in the 1840s reached 2,500, exceeded 1,000 in the 1870s. For the most part the town was on the Savannah River floodplain. Under protection of the Clarks Hill Dam and Lake, adjacent North Augusta has begun to develop on the grounds of old Hamburg. James E. Broome, governor of Florida from 1853-1857. A.

Black people is a term used in certain countries in based systems of racial classification or of ethnicity, to describe persons who are perceived to be dark-skinned compared to other populations. As such, the meaning of the expression varies both between and within societies, depends on context. For many other individuals and countries, "black" is perceived as a derogatory, reductive or otherwise unrepresentative label, as a result is neither used nor defined. Different societies apply differing criteria regarding, classified as "black", these social constructs have changed over time. In a number of countries, societal variables affect classification as much as skin color, the social criteria for "blackness" vary. In the United Kingdom, "black" was equivalent with "person of color", a general term for non-European peoples. In South Africa and Latin America, mixed-race people are not classified as "black". In other regions such as Australasia, settlers applied the term "black" or it was used by local populations with different histories and ancestral backgrounds.
The Romans interacted with and conquered parts of Mauretania, an early state that covered modern Morocco, western Algeria, the Spanish cities Ceuta and Melilla during the classical period. The people of the region were noted in Classical literature as Mauri, subsequently rendered as Moors in English. Numerous communities of dark-skinned peoples are present in North Africa, some dating from prehistoric communities. Others are descendants of the historical Trans-Saharan trade in peoples and/or, after the Arab invasions of North Africa in the 7th century, descendants of slaves from the Arab Slave Trade in North Africa. In the 18th century, the Moroccan Sultan Moulay Ismail "the Warrior King" raised a corps of 150,000 black soldiers, called his Black Guard. According to Carlos Moore, resident scholar at Brazil's University of the State of Bahia, in the 21st century Afro-multiracials in the Arab world, including Arabs in North Africa, self-identify in ways that resemble multi-racials in Latin America.
He claims that black-looking Arabs, much like black-looking Latin Americans, consider themselves white because they have some distant white ancestry. Egyptian President Anwar Sadat had a mother, a dark-skinned Nubian Sudanese woman and a father, a lighter-skinned Egyptian. In response to an advertisement for an acting position, as a young man he said, "I am not white but I am not black either. My blackness is tending to reddish". Due to the patriarchal nature of Arab society, Arab men, including during the slave trade in North Africa, enslaved more black women than men, they used more black female slaves in domestic agriculture than males. The men interpreted the Qur'an to permit sexual relations between a male master and his female slave outside of marriage, leading to many mixed-race children; when an enslaved woman became pregnant with her Arab master's child, she was considered as umm walad or "mother of a child", a status that granted her privileged rights. The child was given rights of inheritance to the father's property, so mixed-race children could share in any wealth of the father.
Because the society was patrilineal, the children took their fathers' social status at birth and were born free. Some succeeded their fathers as rulers, such as Sultan Ahmad al-Mansur, who ruled Morocco from 1578 to 1608, he was not technically considered as a mixed-race child of a slave. In early 1991, non-Arabs of the Zaghawa tribe of Sudan attested that they were victims of an intensifying Arab apartheid campaign, segregating Arabs and non-Arabs. Sudanese Arabs, who controlled the government, were referred to as practicing apartheid against Sudan's non-Arab citizens; the government was accused of "deftly manipulat Arab solidarity" to carry out policies of apartheid and ethnic cleansing. American University economist George Ayittey accused the Arab government of Sudan of practicing acts of racism against black citizens. According to Ayittey, "In Sudan... the Arabs monopolized power and excluded blacks – Arab apartheid." Many African commentators joined Ayittey in accusing Sudan of practising Arab apartheid.
In the Sahara, the native Tuareg Berber populations kept "Negro" slaves. Most of these captives were of Nilotic extraction, were either purchased by the Tuareg nobles from slave markets in the Western Sudan or taken during raids, their origin is denoted via the Ahaggar Berber word Ibenheren, which alludes to slaves that only speak a Nilo-Saharan language. These slaves were sometimes known by the borrowed Songhay term Bella; the Sahrawi autochthones of the Western Sahara observed a class system consisting of high castes and low castes. Outside of these traditional tribal boundaries were "Negro" slaves, who were drawn from the surrounding areas. In parts of the Horn of Africa, the local Afroasiatic speaking populations have long adhered to a construct similar to that of the Sahara and Maghreb. In Ethiopia and Somalia, the slave classes consisted of individuals of Nilotic and Bantu origin who were collectively known as Shanqella and Adone; these captives and others of analogous morphology were distinguished as tsalim barya in contrast with the Afroasiatic-speaking nobles or saba qayh.
The earliest representation of this tradition dates from a seventh or eighth century BC inscription belonging to the Kingdom of Damat. In South Africa, the period of colonization resulted in many unions and marriages between European men and Bantu and Kho
