Clark County is a county located in the U. S. state of Nevada. As of the 2010 census, the population was 1,951,269 and it is by far the most populous county in Nevada, accounting more than two-thirds of its residents. Las Vegas, Nevadas most populous city, has been the county seat since the county was established, the county was formed by the Nevada Legislature by splitting off a portion of Lincoln County on February 5,1909, and came into existence on July 1,1909. The Las Vegas Valley, a 600 sq mi basin, includes Las Vegas as well as the primary population center. Much of the county was part of Pah-Ute County, Arizona Territory before Nevada became a state. The county was named for William Andrews Clark, a Montana copper magnate, Clark was largely responsible for the construction of the Los Angeles and Salt Lake Railroad through the area, a factor heavily contributing to the regions early development. Clark County is today known as a major tourist destination, with 150,000 hotel rooms. The Las Vegas Strip, home to most of the known to many around the world, is located not within the City of Las Vegas city limits. It is, however, located in the Las Vegas Valley, according to the U. S. Census Bureau, the county has a total area of 8,061 square miles, of which 7,891 square miles is land and 169 square miles is water. The Colorado River forms the southeastern boundary, with Hoover Dam forming Lake Mead along much of its length. The lowest point in the state of Nevada is located on the Colorado River just south of Laughlin in Clark County, where it flows out of Nevada into California and Arizona. By definition, Greater Las Vegas is a valley, surrounded by four mountain ranges, with nearby Mount Charleston being the highest elevation at 11,918 ft. Other than the forests on Mount Charleston, the geography in Clark County is a desert, creosote bushes are the main native vegetation, and the mountains are mostly rocky with little vegetation. Many of these are located in, or partially located in,24. 50% of all households were made up of individuals and 6. 70% had someone living alone who was 65 years of age or older.

Nevada

Nevada is a state in the Western, Mountain West, and Southwestern regions of the United States of America. Nevada is the 7th most extensive, the 34th most populous, nearly three-quarters of Nevadas people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the states four largest incorporated cities are located. Nevada is officially known as the Silver State because of the importance of silver to its history and economy. It is also known as the Battle Born State, because it achieved statehood during the Civil War, as the Sage-brush State, for the plant of the same name. Nevada borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, Nevada is largely desert and semi-arid, much of it located within the Great Basin. Areas south of the Great Basin are located within the Mojave Desert, while Lake Tahoe, about 86% of the states land is managed by various jurisdictions of the U. S. federal government, both civilian and military. Before European contact, Native Americans of the Paiute, Shoshone, the first Europeans to explore the region were Spanish. They called the region Nevada because of the snow covered the mountains in winter. The area formed part of the Viceroyalty of New Spain, the United States annexed the area in 1848 after its victory in the Mexican–American War, and it was incorporated as part of Utah Territory in 1850. The discovery of silver at the Comstock Lode in 1859 led to a boom that became an impetus to the creation of Nevada Territory out of western Utah Territory in 1861. Nevada became the 36th state on October 31,1864, as the second of two added to the Union during the Civil War. Nevada has a reputation for its libertarian laws, in 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populated state. However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in the 20th century, Nevada is the only U. S. state where prostitution is legal, though it is illegal in Clark County, Washoe County and Carson City. The tourism industry remains Nevadas largest employer, with mining continuing as a sector of the economy. The name Nevada comes from the Spanish nevada, meaning snow-covered, most Nevadans pronounce the second syllable of their state name using the vowel of trap. Many from outside the Western United States pronounce it with the vowel of father, although the latter pronunciation is closer to the Spanish pronunciation, it is not the pronunciation preferred by most Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternate pronunciation of Nevada, though the bill was not supported by most legislators, the Nevadan pronunciation is the de facto official one, since it is the one used by the state legislature. Nevada is almost entirely within the Basin and Range Province, and is broken up by many mountain ranges

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

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

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
