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

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

UTC−05,00 is a time offset that subtracts five hours from Coordinated Universal Time. In North America, it is observed in the Eastern Time Zone during standard time, the western Caribbean uses it year round. The southwestern and northwestern portions of Indiana Mexico – Central Zone Central, in most of Mexico, daylight time starts a few weeks after the United States. Communities on the U. S. border that observe Central Time follow the U. S. daylight time schedule

ZIP Code
–
ZIP Codes are a system of postal codes used by the United States Postal Service since 1963. The term ZIP, an acronym for Zone Improvement Plan, was chosen to suggest that the travels more efficiently, and therefore more quickly. The basic format consists of five numerical digits, an extended ZIP+4 code, introduced in 1983, includes the five digits of the ZIP Code, a hyphen, and four additional digits that determine a more specific location within a given ZIP Code. The term ZIP Code was originally registered as a servicemark by the U. S. Postal Service, USPS style for ZIP is all caps and the c in code is also capitalized, although style sheets for some publications use sentence case or lowercase. The early history and context of postal codes began with postal district/zone numbers, the United States Post Office Department implemented postal zones for numerous large cities in 1943. For example, Mr. John Smith 3256 Epiphenomenal Avenue Minneapolis 16, by the early 1960s a more organized system was needed, and on July 1,1963, non-mandatory five-digit ZIP Codes were introduced nationwide. Three months later, on October 1,1963, the U. S, an earlier list in June had proposed capitalized abbreviations ranging from two to five letters. The abbreviations have remained unchanged, with one exception, according to the historian of the U. S. Robert Moon, an employee of the post office, is considered the father of the ZIP Code, he submitted his proposal in 1944 while working as a postal inspector. The post office gives credit to Moon only for the first three digits of the ZIP Code, which describe the sectional center facility or sec center, an SCF is a central mail processing facility with those three digits. The SCF sorts mail to all post offices with those first three digits in their ZIP Codes, the mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. The United States Post Office used a character, which it called Mr. ZIP. He was often depicted with a such as USE ZIP CODE in the selvage of panes of stamps or on labels contained in, or the covers of. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4, often called plus-four codes, add-on codes, or add ons. But initial attempts to promote use of the new format met with public resistance. For Post Office Boxes, the rule is that each box has its own ZIP+4 code. However, there is no rule, so the ZIP+4 Code must be looked up individually for each box. It is common to use add-on code 9998 for mail addressed to the postmaster,9999 for general delivery, for a unique ZIP Code, the add-on code is typically 0001

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

Illinois
–
Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 6th most populous state and 25th largest state in terms of land area, the word Illinois comes from a French rendering of a native Algonquin word. For decades, OHare International Airport has been ranked as one of the worlds busiest airports, Illinois has long had a reputation as a bellwether both in social and cultural terms and politics. With the War of 1812 Illinois growth slowed as both Native Americans and Canadian forces often raided the American Frontier, mineral finds and timber stands also had spurred immigration—by the 1810s, the Eastern U. S. Railroads arose and matured in the 1840s, and soon carried immigrants to new homes in Illinois, as well as being a resource to ship their commodity crops out to markets. Railroads freed most of the land of Illinois and other states from the tyranny of water transport. By 1900, the growth of jobs in the northern cities and coal mining in the central and southern areas attracted a new group of immigrants. Illinois was an important manufacturing center during both world wars, the Great Migration from the South established a large community of African Americans in Chicago, who created the citys famous jazz and blues cultures. Three U. S. presidents have been elected while living in Illinois, Abraham Lincoln, Ulysses S. Grant, additionally, Ronald Reagan, whose political career was based in California, was the only U. S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official slogan, Land of Lincoln. The Abraham Lincoln Presidential Library and Museum is located in the capital of Springfield. Illinois is the spelling for the early French Catholic missionaries and explorers name for the Illinois Native Americans. American scholars previously thought the name Illinois meant man or men in the Miami-Illinois language and this etymology is not supported by the Illinois language, as the word for man is ireniwa and plural men is ireniwaki. The name Illiniwek has also said to mean tribe of superior men. The name Illinois derives from the Miami-Illinois verb irenwe·wa he speaks the regular way and this was taken into the Ojibwe language, perhaps in the Ottawa dialect, and modified into ilinwe·. The French borrowed these forms, changing the ending to spell it as -ois. The current spelling form, Illinois, began to appear in the early 1670s, the Illinois name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans, the Koster Site has been excavated and demonstrates 7,000 years of continuous habitation

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

County seat
–
A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China, in the United Kingdom and Ireland, county towns have a similar function. In the United States, counties are the subdivisions of a state. Depending on the state, counties may provide services to the public, impose taxes. Some types of subdivisions, such as townships, may be incorporated or unincorporated. The city, town, or populated place that houses county government is known as the seat of its respective county, a county seat is usually, 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, likewise, 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, in some of the colonial states, county seats include or formerly included Court House as part of their name. Most counties have only one county seat, an example is Harrison County, Mississippi, which lists both Biloxi and Gulfport as county seats. The practice of multiple county seat towns dates from the days when travel was difficult, 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, for example, the official county seat is Greensboro, but an additional courthouse has been located in nearby High Point since 1938. For example, Clearwater is the county seat of Pinellas County, Florida, in New England, the town, not the county, is the primary division of local government. Historically, counties in this region have served mainly as dividing lines for the judicial systems. Connecticut and Rhode Island have no county level of government and thus no county seats, in Vermont, Massachusetts, and Maine the county seats are legally designated shire towns. County government consists only of a Superior Court and Sheriff, both located in the shire town. Bennington County has two towns, but the Sheriff is located in Bennington. In Massachusetts, most government functions which would otherwise be performed by county governments in other states are performed by town governments. As such, Massachusetts has dissolved many of its county governments, two counties in South Dakota have their county seat and government services centered in a neighboring county

1860 United States Census
–
The United States Census of 1860 was the eighth Census conducted in the United States starting June 1,1860, and lasting five months. It determined the population of the United States to be 31,443,321, the total population included 3,953,761 slaves, representing 12. 6% of the total population. By the time the 1860 census returns were ready for tabulation, as a result, Census Superintendent Joseph C. G. Kennedy and his staff produced only an abbreviated set of public reports, without graphic or cartographic representations. The statistics did allow the Census staff to produce a display, including preparing maps of Southern states. These maps displayed militarily vital topics, including population, slave population, predominant agricultural products. The 1860 census Schedule 1 was one of two schedules that counted the population of the United States, the other was Schedule 2, aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System. National data reveals that farmers made up nearly 10% of utilized occupations, farm laborers represent the next highest percent with 3. 2%, followed by general laborers at 3. 0%. More localized data shows that other occupations were common, in the town of Essex, Massachusetts, a large section of the women in the labor force were devoted to shoe-binding, while for men the common occupations were farming and shoe-making. IPUMS data also notes that the share of the population that had enrolled in school or marked as Student stood at 0. 2%. The census of 1860 was the last in which much of Southern wealth was held as slaves—still legally considered property, G. G. Kennedy U. S.

1890 United States Census
–
The Eleventh United States Census was taken beginning June 2,1890. 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. Data was entered on a machine readable medium, punched cards, the total population of 62,947,714, the family, or rough, count, 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 America, down from 400,764 Native Americans identified in the census of 1850. The 1890 census announced that the region of the United States no longer existed. 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. Almost all the schedules were damaged in a fire in the basement of the Commerce Building in Washington. Some 25% of the materials were presumed destroyed and another 50% damaged by smoke, the damage to the records led to an outcry for a permanent National Archives. The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, congress authorized destruction of that list of records on February 21,1933, and the surviving original 1890 census records were destroyed by government order by 1934 or 1935. The other censuses for which information has been lost are the 1800 and 1810 enumerations. Mayo-Smith, Richmond, The Eleventh Census of the United States
