City
–
A city is a large and permanent human settlement. Cities generally have complex systems for sanitation, utilities, land usage, housing, a big city or metropolis usually has associated suburbs and exurbs. Such cities are associated with metropolitan areas and urban areas. Once a city expands far enough to another city, this region can be deemed a conurbation or megalopolis. Damascus is arguably the oldest city in the world, in terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai. There is not enough evidence to assert what conditions gave rise to the first cities, some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces. The conventional view holds that cities first formed after the Neolithic revolution, the Neolithic revolution brought agriculture, which made denser human populations possible, thereby supporting city development. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and to settle near others who lived by agricultural production, the increased population density encouraged by farming and the increased output of food per unit of land created conditions that seem more suitable for city-like activities. In his book, Cities and Economic Development, Paul Bairoch takes up position in his argument that agricultural activity appears necessary before true cities can form. According to Vere Gordon Childe, for a settlement to qualify as a city, it must have enough surplus of raw materials to support trade and a relatively large population. To illustrate this point, Bairoch offers an example, Western Europe during the pre-Neolithic, when the cost of transport is taken into account, the figure rises to 200,000 square kilometres. Bairoch noted that this is roughly the size of Great Britain, the urban theorist Jane Jacobs suggests that city formation preceded the birth of agriculture, but this view is not widely accepted. In his book City Economics, Brendan OFlaherty asserts Cities could persist—as they have for thousands of years—only if their advantages offset the disadvantages, OFlaherty illustrates two similar attracting advantages known as increasing returns to scale and economies of scale, which are concepts usually associated with businesses. Their applications are seen in more basic economic systems as well, increasing returns to scale occurs when doubling all inputs more than doubles the output an activity has economies of scale if doubling output less than doubles cost. To offer an example of these concepts, OFlaherty makes use of one of the oldest reasons why cities were built, in this example, the inputs are anything that would be used for protection and the output is the area protected and everything of value contained in it. OFlaherty then asks that we suppose the protected area is square, the advantage is expressed as, O = s 2, where O is the output and s stands for the length of a side. This equation shows that output is proportional to the square of the length of a side, the inputs depend on the length of the perimeter, I =4 s, where I stands for the quantity of inputs. So there are increasing returns to scale, O = I2 /16 and this equation shows that with twice the inputs, you produce quadruple the output

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

U.S. state
–
A U. S. state is a constituent political entity of the United States of America. There are 50 states, which are together in a union with each other. Each state holds administrative jurisdiction over a geographic territory. Due to the shared sovereignty between each state and the government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders. States range in population from just under 600,000 to over 39 million, four states use the term commonwealth rather than state in their full official names. States are divided into counties or county-equivalents, which may be assigned some local authority but are not sovereign. County or county-equivalent structure varies widely by state, State governments are allocated power by the people through their individual constitutions. All are grounded in principles, and each provides for a government. States possess a number of powers and rights under the United States Constitution, Constitution has been amended, and the interpretation and application of its provisions have changed. The general tendency has been toward centralization and incorporation, with the government playing a much larger role than it once did. There is a debate over states rights, which concerns the extent and nature of the states powers and sovereignty in relation to the federal government. States and their residents are represented in the federal Congress, a legislature consisting of the Senate. Each state is represented in the Senate by two senators, and is guaranteed at least one Representative in the House, members of the House are elected from single-member districts. Representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census, the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to 50, alaska and Hawaii are the most recent states admitted, both in 1959. The Constitution is silent on the question of states have the power to secede from the Union. Shortly after the Civil War, the U. S. Supreme Court, in Texas v. White, as a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Cass County, Texas
–
Cass County is a county located in the U. S. state of Texas. As of the 2010 census, its population was 30,464, the county was named for Lewis Cass, a senator from Michigan who favored the annexation of Texas. Cass County was formed in 1846 from sections of Bowie County and it was named for Lewis Cass, a U. S. Senator from Michigan who had favored the annexation of Texas to the United States, from 1861 to 1871, this county was known as Davis County, after Jefferson Davis, the president of the Confederate States of America.

2010 United States Census
–
The 2010 United States Census, is the twenty-third and currently most recent United States national census. National Census Day, the day used for the census, was April 1,2010. As part of a drive to increase the accuracy,635,000 temporary enumerators were hired. The population of the United States was counted as 308,745,538, 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 personally inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, 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 approximately 134 million on April 1,2010. 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 Census Bureau delivered population information to the president for apportionment, personally identifiable information will be available in 2082. The Census Bureau did not use a form for the 2010 Census. In several previous censuses, one in six households received this long form, 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 1s age and Person 1s date of birth, is Person 1 of Hispanic, Latino, or Spanish origin. Does Person 1 sometimes live or stay somewhere else, the form included space to repeat some or all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, 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 basis will receive the survey each year. In June 2009, the U. S. Census Bureau announced that it would count same-sex married couples, however, the final form did not contain a separate same-sex married couple option

Central Time Zone
–
The North American Central Time Zone is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time is six hours behind Coordinated Universal Time, during summer most of the zone uses daylight saving time, and changes to Central Daylight Time which is five hours behind UTC. The province of Manitoba is the province or territory in Canada that observes Central Time in all areas. Also, most of the province of Saskatchewan is on Central Standard Time year-round, major exceptions include Lloydminster, a city situated on the boundary between Alberta and Saskatchewan. The city charter stipulates that it shall observe Mountain Time and DST, putting the community on the time as all of Alberta, including the major cities of Calgary. As a result, during the summer, clocks in the province match those in Alberta. The Central Time Zone is the second most populous in the US after the Eastern Time Zone, lanett and Valley observe Eastern Time historically because they were textile mill towns and the original home office of their mills was in West Point, Georgia. Some eastern counties observe Central Time because they are close to the border of the Middle Tennessee counties surrounding the Nashville metropolitan area. Louisiana Michigan, All of Michigan observes Eastern Time except the four Upper Peninsula counties that border Wisconsin, other westernmost counties from this area such as Ontonagon observe Eastern Time. South Dakota, Eastern half as divided by the Missouri river adjacent to the state capital, note, the metropolitan area of Pierre is Central, including Fort Pierre. Wisconsin Most of Mexico—roughly the eastern three-fourths—lies in the Central Time Zone, except for six northwestern states, the federal entities of Mexico that observe Central Time, Belize, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua all use Central Standard Time year-round. The Galápagos Islands in Ecuador uses Central Standard Time all year-round, Daylight saving time is in effect in much of the Central time zone between mid-March and early November. The modified time is called Central Daylight Time and is UTC−5, in Canada, Saskatchewan does not observe a time change. One reason that Saskatchewan does not take part in a change is that, geographically. The province elected to move onto permanent daylight saving by being part of the Central Time Zone, Mexico decided not to go along with this change and observes their horario de verano from the first Sunday in April to the last Sunday in October. In December 2009, the Mexican Congress allowed ten border cities, eight of which are in states that observe Central Time, to adopt the U. S. daylight time schedule effective in 2010

Daylight saving time
–
Daylight saving time is the practice of advancing clocks during summer months by one hour so that evening daylight lasts an hour longer, while sacrificing normal sunrise times. Typically, regions that use Daylight Savings Time adjust clocks forward one hour close to the start of spring, American inventor and politician Benjamin Franklin proposed a form of daylight time in 1784. New Zealander George Hudson proposed the idea of saving in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30,1916, many countries have used it at various times since then, particularly since the energy crisis of the 1970s. The practice has both advocates and critics, DST clock shifts sometimes complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns. Computer software often adjusts clocks automatically, but policy changes by various jurisdictions of DST dates, industrialized societies generally follow a clock-based schedule for daily activities that do not change throughout the course of the year. The time of day that individuals begin and end work or school, North and south of the tropics daylight lasts longer in summer and shorter in winter, with the effect becoming greater as one moves away from the tropics. However, they will have one hour of daylight at the start of each day. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, DST is also of little use for locations near the equator, because these regions see only a small variation in daylight in the course of the year. After ancient times, equal-length civil hours eventually supplanted unequal, so civil time no longer varies by season, unequal hours are still used in a few traditional settings, such as some monasteries of Mount Athos and all Jewish ceremonies. This 1784 satire proposed taxing window shutters, rationing candles, and waking the public by ringing church bells, despite common misconception, Franklin did not actually propose DST, 18th-century Europe did not even keep precise schedules. However, this changed as rail transport and communication networks came to require a standardization of time unknown in Franklins day. Modern DST was first proposed by the New Zealand entomologist George Hudson, whose shift work job gave him time to collect insects. An avid golfer, he also disliked cutting short his round at dusk and his solution was to advance the clock during the summer months, a proposal he published two years later. The proposal was taken up by the Liberal Member of Parliament Robert Pearce, a select committee was set up to examine the issue, but Pearces bill did not become law, and several other bills failed in the following years. Willett lobbied for the proposal in the UK until his death in 1915, william Sword Frost, mayor of Orillia, Ontario, introduced daylight saving time in the municipality during his tenure from 1911 to 1912. Starting on April 30,1916, the German Empire and its World War I ally Austria-Hungary were the first to use DST as a way to conserve coal during wartime, Britain, most of its allies, and many European neutrals soon followed suit. Russia and a few other countries waited until the year
