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
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
William Jefferson Clinton is an American politician who served as the 42nd president of the United States from 1993 to 2001. Prior to the presidency, he was the governor of Arkansas from 1979 to 1981, again from 1983 to 1992, the attorney general of Arkansas from 1977 to 1979. A member of the Democratic Party, Clinton was ideologically a New Democrat, many of his policies reflected a centrist "Third Way" political philosophy. Clinton was born and raised in Arkansas and attended Georgetown University, University College and Yale Law School, he met Hillary Rodham at Yale and married her in 1975. After graduating, Clinton returned to Arkansas and won election as the Attorney General of Arkansas, serving from 1977 to 1979; as Governor of Arkansas, he overhauled the state's education system and served as chairman of the National Governors Association. Clinton was elected president in 1992. At age 46, he became the first from the Baby Boomer generation. Clinton presided over the longest period of peacetime economic expansion in American history.
He signed into law the North American Free Trade Agreement but failed to pass his plan for national health care reform. In the 1994 elections, the Republican Party won unified control of the Congress for the first time in 40 years. In 1996, Clinton became the first Democrat since Franklin D. Roosevelt to be elected to a second full term, he passed welfare reform and the State Children's Health Insurance Program, as well as financial deregulation measures, including the Gramm–Leach–Bliley Act and the Commodity Futures Modernization Act of 2000. In 1998, Clinton was impeached by the House of Representatives for perjury and obstruction of justice following allegations that he committed perjury and obstructed justice to conceal an affair that he had with Monica Lewinsky, a 22-year old White House Intern. Clinton was completed his term in office, he is only the second U. S. president—following Andrew Johnson 131 years earlier—to be impeached. During the last three years of Clinton's presidency, the Congressional Budget Office reported a budget surplus, the first such surplus since 1969.
In foreign policy, Clinton ordered U. S. military intervention in the Bosnian and Kosovo wars, signed the Iraq Liberation Act in opposition to Saddam Hussein, participated in the 2000 Camp David Summit to advance the Israeli–Palestinian peace process, assisted the Northern Ireland peace process. Clinton left office with the highest end-of-office approval rating of any U. S. president since World War II, has continually scored high in the historical rankings of U. S. presidents placing in the top third. Since leaving office, he has been involved in humanitarian work, he created the William J. Clinton Foundation to address international causes such as the prevention of AIDS and global warming, he has remained active in politics by campaigning for Democratic candidates, including the presidential campaigns of his wife and Barack Obama. In 2004, Clinton published My Life. In 2009, he was named the United Nations Special Envoy to Haiti and after the 2010 Haiti earthquake, he teamed with George W. Bush to form the Clinton Bush Haiti Fund.
In addition, he secured the release of two American journalists imprisoned by North Korea, visiting the capital Pyongyang and negotiating their release with Kim Jong-il. Clinton was born William Jefferson Blythe III on August 19, 1946, at Julia Chester Hospital in Hope, Arkansas, he is the son of William Jefferson Blythe Jr. a traveling salesman who had died in an automobile accident three months before his birth, Virginia Dell Cassidy. His parents had married on September 4, 1943, but this union proved to be bigamous, as Blythe was still married to his third wife. Virginia traveled to New Orleans to study nursing soon after Bill was born, leaving him in Hope with her parents Eldridge and Edith Cassidy, who owned and ran a small grocery store. At a time when the southern United States was racially segregated, Clinton's grandparents sold goods on credit to people of all races. In 1950, Bill's mother returned from nursing school and married Roger Clinton Sr. who co-owned an automobile dealership in Hot Springs, Arkansas with his brother and Earl T. Ricks.
The family moved to Hot Springs in 1950. Although he assumed use of his stepfather's surname, it was not until Clinton turned 15 that he formally adopted the surname Clinton as a gesture toward his stepfather. Clinton said that he remembered his stepfather as a gambler and an alcoholic who abused his mother and half-brother, Roger Clinton Jr. to the point where he intervened multiple times with the threat of violence to protect them. In Hot Springs, Clinton attended St. John's Catholic Elementary School, Ramble Elementary School, Hot Springs High School, where he was an active student leader, avid reader, musician. Clinton was in the chorus and played the tenor saxophone, winning first chair in the state band's saxophone section, he considered dedicating his life to music, but as he noted in his autobiography My Life: Clinton began an interest in law at Hot Springs High, when he took up the challenge to argue the defense of the ancient Roman Senator Catiline in a mock trial in his Latin class.
After a vigorous defense that made use of his "budding rhetorical and political skills", he told the Latin teacher Elizabeth Buck that it "made him realize that someday he would study law". Clinton has identified two influential moments in his life, both occurring in 1963, that contributed to his decision to become a public figure. One was his visit as a Boys Nation senator to

Nevada County, Arkansas
Nevada County is a county located in the southwestern part of the U. S. state of Arkansas. As of the 2010 census, the population was 8,997, less than half of its peak in 1920; the county seat is Prescott. Nevada County is Arkansas's 63rd county, formed during the Reconstruction era on March 20, 1871, from portions of Hempstead and Columbia counties, it was named after the state of Nevada because of the perceived similarity between their physical shapes. In contrast with how people pronounce the state's name, the local pronunciation for this Arkansas county is "nuh-VAY-duh", it is dry county. Dorcheat Bayou, a 122-mile stream, begins in Nevada County, it flows south into Columbia County and across the border into Webster Parish, where it flows into Lake Bistineau and Loggy Bayou, forming a continuous passage to the Red River. In the 19th century, the bayou was navigable for three to six months by steamboat from Bistineau to Minden; the watershed had fertile farmland and swampland. The bayou is now popular for its natural environment.
This area was occupied by members of the Caddoan Confederacy, whose territory extended into present-day Texas and Louisiana. They settled along the waterways, using them for fishing. Colonial French and European-American settlers took over lands along the waterways, which formed their basic transportation routes well into the 19th century. After the Congress repealed Prohibition in the early 20th century, Nevada County voted to retain it and the county is still "dry". According to the U. S. Census Bureau, the county has a total area of 621 square miles, of which 618 square miles is land and 2.8 square miles is water. The county is bounded on the north by the Little Missouri River, a branch of the Ouachita River, drained by several tributaries of that stream and of Red River. Nevada County is alternately considered as part of the greater regions of South Arkansas or Southwest Arkansas. Clark County Ouachita County Columbia County Lafayette County Hempstead County Pike County The population declined by more than half from 1920 to 1970, due to mechanization of agriculture and the decline of the lumber industry causing loss of jobs.
In addition, blacks left in the Great Migration to midwestern and western industrial cities, where they found better work and less social oppression. As of the 2000 United States Census, there were 9,955 people, 3,893 households, 2,721 families residing in the county; the population density was 16 people per square mile. There were 4,751 housing units at an average density of 8 per square mile; the racial makeup of the county was 66.90% White, 31.18% Black or African American, 0.38% Native American, 0.06% Asian, 0.85% from other races, 0.62% from two or more races. 1.52% of the population were Hispanic or Latino of any race. There were 3,893 households out of which 31.40% had children under the age of 18 living with them, 51.90% were married couples living together, 14.00% had a female householder with no husband present, 30.10% were non-families. 27.80% of all households were made up of individuals and 13.70% had someone living alone, 65 years of age or older. The average household size was 2.48 and the average family size was 3.02.
In the county, the population was spread out with 25.20% under the age of 18, 8.70% from 18 to 24, 26.10% from 25 to 44, 23.80% from 45 to 64, 16.10% who were 65 years of age or older. The median age was 38 years. For every 100 females, there were 94.40 males. For every 100 females age 18 and over, there were 89.90 males. The median income for a household in the county was $26,962, the median income for a family was $33,095. Males had a median income of $27,888 versus $17,920 for females; the per capita income for the county was $14,184. About 18.30% of families and 22.80% of the population were below the poverty line, including 28.00% of those under age 18 and 27.10% of those age 65 or over.

Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.
