A town is a human settlement. Towns are larger than villages but smaller than cities, though the criteria to distinguish them vary between different parts of the world; the word town shares an origin with the German word Zaun, the Dutch word tuin, the Old Norse tun. The German word Zaun comes closest to the original meaning of the word: a fence of any material. An early borrowing from Celtic *dunom. In English and Dutch, the meaning of the word took on the sense of the space which these fences enclosed. In England, a town was a small community that could not afford or was not allowed to build walls or other larger fortifications, built a palisade or stockade instead. In the Netherlands, this space was a garden, more those of the wealthy, which had a high fence or a wall around them. In Old Norse tun means a place between farmhouses, the word is still used in a similar meaning in modern Norwegian. In Old English and Early and Middle Scots, the words ton, etc. could refer to diverse kinds of settlements from agricultural estates and holdings picking up the Norse sense at one end of the scale, to fortified municipalities.
If there was any distinction between toun and burgh as claimed by some, it did not last in practice as burghs and touns developed. For example, "Edina Burgh" or "Edinburgh" was built around a fort and came to have a defensive wall. In some cases, "town" is an alternative name for "city" or "village". Sometimes, the word "town" is short for "township". In general, today towns can be differentiated from townships, villages, or hamlets on the basis of their economic character, in that most of a town's population will tend to derive their living from manufacturing industry and public services rather than primary industry such as agriculture or related activities. A place's population size is not a reliable determinant of urban character. In many areas of the world, e.g. in India at least until recent times, a large village might contain several times as many people as a small town. In the United Kingdom, there are historical cities; the modern phenomenon of extensive suburban growth, satellite urban development, migration of city dwellers to villages has further complicated the definition of towns, creating communities urban in their economic and cultural characteristics but lacking other characteristics of urban localities.
Some forms of non-rural settlement, such as temporary mining locations, may be non-rural, but have at best a questionable claim to be called a town. Towns exist as distinct governmental units, with defined borders and some or all of the appurtenances of local government. In the United States these are referred to as "incorporated towns". In other cases the town lacks its own governance and is said to be "unincorporated". Note that the existence of an unincorporated town may be set out by other means, e.g. zoning districts. In the case of some planned communities, the town exists in the form of covenants on the properties within the town; the United States Census identifies many census-designated places by the names of unincorporated towns which lie within them. The distinction between a town and a city depends on the approach: a city may be an administrative entity, granted that designation by law, but in informal usage, the term is used to denote an urban locality of a particular size or importance: whereas a medieval city may have possessed as few as 10,000 inhabitants, today some consider an urban place of fewer than 100,000 as a town though there are many designated cities that are much smaller than that.
Australian geographer Thomas Griffith Taylor proposed a classification of towns based on their age and pattern of land use. He identified five types of town: Infantile towns, with no clear zoning Juvenile towns, which have developed an area of shops Adolescent towns, where factories have started to appear Early mature towns, with a separate area of high-class housing Mature towns, with defined industrial and various types of residential area In Afghanistan and cities are known as shār; as the country is an rural society with few larger settlements, with major cities never holding more than a few hundred thousand inhabitants before the 2000s, the lingual tradition of the country does not discriminate between towns and cities. In Albania "qytezë" means town, similar with the word for city. Although there is no official use of the term for any settlement. In Albanian "qytezë" means "small city" or "new city", while in ancient times "small residential center within the walls of a castle"; the center is a population group, larger than a village, smaller than a city.
Though the village is bigger than a hamlet In Australia, towns or "urban centre localities" are understood to be those centers of population not formally declared to be cities and having a population in excess of about 200 people. Centers too small to be called towns are understood to be a township. In addition, some local government entities are styled as towns in Queensland, Western Australia and the Northern Territory, before the statewide amalgamations of th
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
Muscle Shoals, Alabama
Muscle Shoals is the largest city in Colbert County, United States. As of the 2010 census, the population of Muscle Shoals was 13,146; the estimated population in 2015 was 13,706. Both the city and the Florence-Muscle Shoals Metropolitan Area are called "the Shoals". Northwest Alabama Regional Airport serves the Shoals region, located in the northwest section of the state. Since the 1960s, the city has been known for music – developing the "Muscle Shoals Sound", as local recording studios produced hit records that shaped the history of popular music. Due to its strategic location along the Tennessee River, Muscle Shoals played a key role in historic land disputes between Native Americans and Anglo-American settlers in the late 18th century and early 19th century. Muscle Shoals was the site of an attempted community development project by Henry Ford in 1922; the original streets of Muscle Shoals were named after streets in Detroit, Michigan due to Henry Ford's influence in the area. Just like Detroit, Woodward Avenue is the name of the main road through the city.
Henry Ford's inability to acquire land from the Tennessee Valley Authority foiled his desire to create a 75-mile industrial megalopolis from Decatur to the tri-state border of Pickwick Lake. The Ford Motor Company operated a plant in the Listerhill community, three miles east of Muscle Shoals, for many years before closing in 1982. There are several explanations on. One is that the city gets its name from a former natural feature of the Tennessee River, namely Muscle Shoals, a shallow zone where mussels were gathered; when the area was first settled, the distinct spelling "mussel" to refer to a shellfish had not yet been adopted. The city is one of four municipalities known as the Quad Cities, the others being Florence and Tuscumbia, all in Alabama. Muscle Shoals was a part of the Cherokee hunting grounds dating to at least the early eighteenth century, if not earlier. After the American Revolution, Cherokee attitudes toward the new U. S. republic were divided. An anti-American faction, dubbed the Chickamauga, separated from more conciliatory Cherokees, moved into present-day south-central and southeastern Tennessee, most of them settling along the Chickamauga River.
They claimed Muscle Shoals as part of their domain, when Anglo-Americans attempted to settle the region in the 1780s and 1790s, the Chickamaugas bitterly resisted them. Upper Creeks, residing in what is now north and central Alabama resented any European or Euro-American presence in the region. A major incident occurred in 1790, when U. S. President George Washington sent an expedition under Major John Doughty in an attempt to establish a fort and trading post at Muscle Shoals; this expedition was nearly annihilated by a Chickamauga and Creek party sent to destroy it, the project was abandoned by Doughty and the administration. Anglo-American settlers in Tennessee continued to agitate for control of the region; the site was desirable, as it controlled access to fine cotton-producing land to its south. In 1797, John Sevier, the first governor of Tennessee, complained to Andrew Jackson that "The prevention of a settlement at or near the Muscle Shoals is a manifest injury done the whole western country."
At Sevier's behest, Jackson attempted to persuade Congress and President John Adams to fund a new expedition to take control of the site, but to no avail. U. S. officials took control of the region in the wake of the U. S. invasion of Creek country during the War of 1812. Jackson and General John Coffee obtained cession of the land from both the Cherokee and Creek by treaty, without permission from the federal government. Secretary of War William H. Crawford refused to recognize the cession, reconfirmed Cherokee ownership, leading to personal enmity between him and Jackson, causing a political struggle over the lands which Jackson and his backers won; when Jackson, as President, implemented the policy of Indian Removal, Muscle Shoals was used as a site from which to exile Upper Creeks to Oklahoma Indian Territory. During World War I President Wilson authorized a dam just downstream of Muscle Shoals to help power nitrate plants for munitions; the first plant started producing nitrates two weeks after the armistice, but the dam was not completed until 1924.
Meanwhile, in 1922 Henry Ford tried to buy the unfinished dam. Congress rejected Ford's offer as too low; the project languished until the Franklin D. Roosevelt administration created the Tennessee Valley Authority in 1933. Muscle Shoals hosted the recording of many hit songs from the 1960s to today at two studios: FAME Studios, founded by Rick Hall, where Arthur Alexander, Percy Sledge, Aretha Franklin, Wilson Pickett, Otis Redding and numerous others recorded. All four of the Quad Cities have contributed to the "Muscle Shoals Sound". In addition to being home to country music band Shenandoah, a number of artists have visited Muscle Shoals to write and record. Both FAME Studios and Muscle Shoals Sound Studio are still in operation in the city. While famous for classic recordings from Rod Stewart, Aretha Franklin, Eric Clapton, Lynyrd Skynyrd, the Rolling Stones, The Allman Brothers, recent hit songs such as "Before He Cheats" by Carrie Underwood and "I Loved Her First" by Heartland continue the city's musical legacy.
George Michael recorded an early, unreleased version of "Careless Whisper" with Jerry Wexler in Muscle Shoals in 1983
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. Census data for about 22% of U. S. househol
Florence is a city in Lauderdale County, United States, in the state's northwest corner. According to the 2010 census, the city's population was 39,319. Florence is the largest and principal city of the Florence-Muscle Shoals Metropolitan Statistical Area. Florence is considered northwestern Alabama's primary economic hub. Annual tourism events include the W. C. Handy Music Festival in the summer and the Renaissance Faire in the fall. Landmarks in Florence include the Rosenbaum House, the only Frank Lloyd Wright-designed home located in Alabama. Florence and Lauderdale County had Eliza Coffee Memorial Hospital. ECM was a 358-bed facility owned by RCCH HealthCare Partners in Tennessee. In 2010 RCCH HealthCare Partners announced; the hospital was completed in December 2018. The type of municipal government is mayor-council. According to the U. S. Census Bureau, Florence has a total area of 25.0 square miles, of which 24.9 square miles is land, 0.1 square miles is water. Florence is located on Wilson Lake and Pickwick Lake, bodies of water on the Tennessee River dammed by Pickwick Dam and Wilson Dams.
Pickwick Lake was created by the Tennessee Valley Authority, one of several alphabet agencies of President Franklin Delano Roosevelt's New Deal. Wilson Dam was authorized by President Woodrow Wilson in 1918 and was the first dam constructed on the Tennessee River. Florence was surveyed for the Cypress Land Company in 1818 by Italian surveyor Ferdinand Sannoner, who named it after Florence, the capital of the Tuscany region of Italy. Florence, Alabama was incorporated in 1826. Florence Female Academy was established in Florence in 1847. By the 1850s it became Florence Synodical Female College, it closed in 1893. A historical marker commemorates the site. According to the 2010 census: 75.0% White 19.4% Black 0.4% Native American 1.4% Asian 0.1% Native Hawaiian or Pacific Islander 1.9% Two or more races 3.6% Hispanic or Latino As of the census of 2000, there were 36,264 people, 15,820 households, 9,555 families residing in the city. The population density was 1,454.6 people per square mile. There were 17,707 housing units at an average density of 710.2 per square mile.
The racial makeup of the city was 78.39% White, 19.20% Black or African American, 0.24% Native American, 0.62% Asian, 0.03% Pacific Islander, 0.54% from other races, 0.97% from two or more races. 1.34% of the population were Hispanic or Latino of any race. There were 15,820 households, out of which 25.9% had children under the age of 18 living with them: 43.6% were married couples living together, 14.0% had a female householder with no husband present, 39.6% were non-families. Nearly 33.8% of all households were made up of individuals, 13.3% had someone living alone, 65 years of age or older. The average household size was 2.20, the average family size was 2.82. In the city, the population was spread out with 21.4% under the age of 18, 13.7% from 18 to 24, 25.7% from 25 to 44, 21.7% from 45 to 64, 17.5% who were 65 years of age or older. The median age was 37 years. For every 100 females, there were 84.0 males. For every 100 females age 18 and over, there were 79.7 males. The city is strictly zoned, therefore seems to be much larger than the population of 40,000.
Communities within Florence that aren't counted towards the population include St. Florian, Happy Hollow, Petersville, Zip City, etc; this explains the metropolitan area being close to 150,000 but the "city" only being home to 40,000. The median income for a household in the city was $28,330, the median income for a family was $40,577. Males had a median income of $34,398 versus $21,385 for females; the per capita income for the city was $19,464. About 14.4% of families and 20.4% of the population were below the poverty line, including 25.9% of those under age 18 and 13.3% of those age 65 or over. Situated in Florence, founded in 1830 as LaGrange College, the University of North Alabama, a public, co-educational, higher education institution, is Alabama's oldest state-certified university; the University is the largest in north Alabama, with an enrollment topping 7,000 for the first time in 2007. International students now compose 10% of the student population; the university is surrounded by historic neighborhoods.
It is located just north of the downtown business district. Kilby Laboratory School, grades K - 6, is affiliated with the university and is the only laboratory school in the state. Florence City Schools is the organization of the K–12 public school system. Florence High School is the main high school, with an enrollment of 1,000 students, it was created by a merger between the previous two city high schools, Bradshaw High School and Coffee High School. Florence High is located at the former Bradshaw site in the eastern part of the city; the merger led to the creation of Florence Middle School and the Florence Freshman Center. The middle school is located at the former Coffee High campus, east of downtown, the Florence Freshman Center is located at the Florence High School campus. There are four private schools in Florence: St. Joseph Regional Catholic School for grades K–8, Mars Hill Bible School, Shoals Christian School, Florence Christian Academy, which are multi-denominational, K–12 schools.
The city has a mayor-council form of government. Council members are elected from six single-member districts, the mayor is elected separately. Mayor Steve HoltSteve Holt was elected

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.
