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

United States
–
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

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

Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, Colorado is the 8th most extensive and the 21st most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1,2016, the state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy silt the river carried from the mountains. The Territory of Colorado was organized on February 28,1861, Colorado is nicknamed the Centennial State because it became a state in the same year as the centennial of the United States Declaration of Independence. Colorado is noted for its landscape of mountains, forests, high plains, mesas, canyons, plateaus, rivers. Denver is the capital and the most populous city of Colorado, residents of the state are properly known as Coloradans, although the term Coloradoan has been used archaically and lives on in the title of Fort Collins newspaper, the Coloradoan. Colorado, Wyoming and Utah are the states which have boundaries defined solely by lines of latitude and longitude. The summit of Mount Elbert at 14,440 feet elevation in Lake County is the highest point in Colorado, Colorado is the only U. S. state that lies entirely above 1,000 meters elevation. The point where the Arikaree River flows out of Yuma County, Colorado and this point, which holds the distinction of being the highest low elevation point of any state, is higher than the high elevation points of 18 states and the District of Columbia. A little less than one half of the area of Colorado is flat, East of the Rocky Mountains are the Colorado Eastern Plains of the High Plains, the section of the Great Plains within Nebraska at elevations ranging from roughly 3,350 to 7,500 feet. The Colorado plains were mostly prairies, but they have many patches of forests, buttes. Eastern Colorado is presently covered in farmland and rangeland, along with small farming villages. Precipitation is fair, averaging from 15 to 25 inches annually, corn, wheat, hay, soybeans, and oats are all typical crops, and most of the villages and towns in this region boast both a water tower and a grain elevator. Irrigation water is available from the South Platte, the Arkansas River, and a few other streams, however, heavy use of ground water from wells for irrigation has caused underground water reserves to decline. As well as agriculture, eastern Colorado hosts considerable livestock, such as cattle ranches. Roughly 70% of Colorados population resides along the edge of the Rocky Mountains in the Front Range Urban Corridor between Cheyenne, Wyoming, and Pueblo, Colorado. This region is protected from prevailing storms that blow in from the Pacific Ocean region by the high Rockies in the middle of Colorado. The Front Range includes Denver, Boulder, Fort Collins, Loveland, Colorado Springs, Pueblo, Greeley and other townships, on the other side of the Rockies, the significant population centers in Western Colorado are the cities of Grand Junction, Durango, and Montrose

In July 1858, gold was discovered along the South Platte River in Arapahoe County and this discovery precipitated the Pikes Peak Gold Rush. Many residents of the region felt disconnected from the remote territorial governments of Kansas and Nebraska. The following month, the Jefferson Territorial Legislature organized 12 counties for the new territory, St. Vrain County was named in honor of Ceran de Hault de Lassus de St. Vrain, the French trader who established the first trading post on the upper South Platte River. St. Vrain County encompassed much of what is today Weld County, the Jefferson Territory never received federal sanction, but on February 28,1861, U. S.

On November 1,1861, the Colorado General Assembly organized 17 counties, including Weld County, Weld County was named for Lewis Ledyard Weld, a lawyer and territorial secretary. He died while serving in the Union Army during the Civil War, until February 9,1887, Weld Countys boundaries included the area now comprising Weld County, Washington County, Logan County, Morgan County, Yuma County, Phillips County, and Sedgwick County. Graham was tried and convicted of the crime, and executed in 1957, in northeastern Weld County, Minuteman III missile silo N-8, one of the many unmanned silos there, was the target of symbolic vandalism by Catholic peace activists in 2002. In 2013, conservative Weld County commissioners began a campaign to secede from the State of Colorado, the legality of this initiative has been questioned by local attorneys.

Census Bureau, the county has an area of 4,017 square miles. It is the third-largest county in Colorado by area, along the western border hilly areas betray the presence of the foothills of the Rocky Mountains further west. The county is served by two highways, I-25 runs through the southwestern corner and I-76 from the south central edge northeastward to the Morgan county border. Other major roads include US85 and US34, which intersect near Greeley, and State Highway 14, pawnee National Grassland Fort Vasquez State History Museum St. The population density was 45 people per square mile, there were 66,194 housing units at an average density of 17 per square mile

Municipal corporation
–
A municipal corporation is the legal term for a local governing body, including cities, counties, towns, townships, charter townships, villages, and boroughs. Municipal incorporation occurs when such municipalities become self-governing entities under the laws of the state or province in which they are located, often, this event is marked by the award or declaration of a municipal charter. A city charter or town charter is a document establishing a municipality such as a city or town. The concept developed in Europe during the Middle Ages and is considered to be a version of a constitution. Traditionally the granting of a charter gave a settlement and its inhabitants the right to town privileges under the feudal system, townspeople who lived in chartered towns were burghers, as opposed to serfs who lived in villages. Towns were often free, in the sense that they were protected by the king or emperor. Today the process for granting charters is determined by the type of government of the state in question, in monarchies, charters are still often a royal charter given by the Crown or the state authorities acting on behalf of the Crown. In federations, the granting of charters may be within the jurisdiction of the level of government such as a state or province. In Brazil, municipal corporations are called municípios and are created by means of legislation at the state level. All municipal corporations must also abide by a municipal law which is passed and amended at the municipal level. In Canada charters are granted by provincial authorities, in Germany, municipal corporations existed since antiquity and through medieval times, until they became out of favour during the absolutism. In order to strengthen the spirit, the city law of Prussia dated 19 November 1808 picked up this concept. It is the basis of municipal law. In India, a Municipal Corporation is a local government body. This standard varies from state to state, according to laws passed by state legislatures, the Corporation of Chennai was the first Municipal Corporation in India. It was established on 29 September 1688 by the British East India Company, the second was Hyderabad Municipal Corporation established in 1869 by the Nizam rulers of Hyderabad State. The third was the Calcutta Municipal Corporation, established in 1876, the Bombay Municipal Corporation was established in 1888 by the Bombay Municipal Corporation Act. The Delhi Municipal Council was established in 1911 during the Delhi Durbar when New Delhi was proclaimed to be the new Capital of India and it was elevated to Municipal Corporation level on 7 April 1958 by an Act of Parliament which established the Municipal Corporation of Delhi

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

Mountain Time Zone
–
The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the specification for the location of time zones. In the United States and Canada, this zone is generically called Mountain Time. Specifically, it is Mountain Standard Time when observing standard time, the term refers to the fact that the Rocky Mountains, which range from northwestern Canada to the US state of New Mexico, are located almost entirely in the time zone. In Mexico, this zone is known as the Pacific Zone. In the United States and Canada, the Mountain Time Zone is one ahead of the Pacific Time Zone and one hour behind the Central Time Zone. Sonora in Mexico and most of Arizona in the United States do not observe daylight saving time, and during the spring, summer, and autumn months they are on the same time as Pacific Daylight Time. The Navajo Nation, most of which lies within Arizona, does observe DST, although the Hopi Nation, as well as some Arizona state offices lying within the Navajo Nation, the largest city in the Mountain Time Zone is Phoenix, Arizona. TV broadcasting in the Mountain Time Zone is typically tape-delayed one hour, sonora – no daylight saving time, always on MST. Sinaloa Revillagigedo Islands, three of the four islands have the time as Mountain Time Zone, Isla Socorro, San Benedicto Island. The following states or areas are part of the Mountain Time Zone, Arizona – no daylight saving time, always on MST, except on the Navajo Nation. Colorado Idaho – southern half, south of the Salmon River Kansas – only the counties of Sherman, Wallace, Greeley and Hamilton, the remaining three counties that border Colorado, Cheyenne, Morton and Stanton, observe Central Time, as do all other Kansas counties. However, the state of Oklahoma is officially in the Central Time Zone. Additionally, northwestern Culberson County, Texas unofficially observes Mountain Time

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

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

Area codes 303 and 720
–
Area codes 303 and 720 are telephone area codes serving the north-central portion of the state of Colorado. They cover Denver, Lakewood, Littleton, Boulder, Longmont, Aurora, Castle Rock, Area code 303 was one of the original area codes put into service in 1947, and originally covered the entire state of Colorado. Despite Colorados dramatic growth during the half of the 20th century. By the late 1980s, an impending number shortage made a split necessary, on March 5,1988, southeastern Colorado, including Colorado Springs and Pueblo, became area code 719. With the 1995 split,303 is the only Colorado area code that does not border another state, the 1995 split was intended as a long-term solution. However, within two years 303 was close to exhaustion once again, the Front Range is home not only to most of Colorados landlines, but also most of the states cell phones, fax machines and pagers. To solve this problem,720 was activated as an overlay on June 1,1998, with the exception mentioned above, all users in the 303/720 area code must dial all ten digits to reach a destination phone, even if that phone is next door. Some users in the area have shortened the two codes to a single digit with a slash for easy writing. So 303-555-1212 is written down as 3/555-1212, or 720-555-1212 is written down as 7/555-1212, list of Colorado area codes NANPA Area Code Map of Colorado Localcallingguide. com NPA303 Localcallingguide. com NPA720

Geographic Names Information System
–
It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names to promote the standardization of feature names, the database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited, variant names, alternatives to official federal names for a feature, are also recorded. Each feature receives a permanent, unique feature record identifier, sometimes called the GNIS identifier, the database never removes an entry, except in cases of obvious duplication. The GNIS accepts proposals for new or changed names for U. S. geographical features, the general public can make proposals at the GNIS web site and can review the justifications and supporters of the proposals. The Bureau of the Census defines Census Designated Places as a subset of locations in the National Geographic Names Database, U. S. Postal Service Publication 28 gives standards for addressing mail. In this publication, the postal service defines two-letter state abbreviations, street identifiers such as boulevard and street, department of the Interior, U. S.

United States Census Bureau
–
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureaus primary mission is conducting the U. S. Census every ten years, in addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, and the Current Population Survey, furthermore, economic and foreign trade indicators released by the federal government typically contain data produced by the Census Bureau. The Bureaus various censuses and surveys help allocate over $400 billion in federal funds every year and help states, local communities, the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States. The Census Bureau now conducts a population count every 10 years in years ending with a 0. Between censuses, the Census Bureau makes population estimates and projections, the Census Bureau is mandated with fulfilling these obligations, the collecting of statistics about the nation, its people, and economy. The Census Bureaus legal authority is codified in Title 13 of the United States Code, the Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures, and housing. Within the bureau, these are known as surveys and are conducted perpetually between and during decennial population counts. The Census Bureau also conducts surveys of manufacturing, retail, service. Between 1790 and 1840, the census was taken by marshals of the judicial districts, the Census Act of 1840 established a central office which became known as the Census Office.

Census
–
A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population, the term is used mostly in connection with national population and housing censuses, other common censuses include agriculture, business, and traffic censuses. United Nations recommendations also cover census topics to be collected, official definitions, classifications, the word is of Latin origin, during the Roman Republic, the census was a list that kept track of all adult males fit for military service. Current administrative data systems allow for other approaches to enumeration with the level of detail but raise concerns about privacy. A census can be contrasted with sampling in which information is obtained only from a subset of a population, typically main population estimates are updated by such intercensal estimates. Modern census data are used for research, business marketing, and planning. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling, similarly, stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official used to apportion the number of elected representatives to regions. In many cases, a carefully chosen random sample can provide accurate information than attempts to get a population census. A census is often construed as the opposite of a sample as its intent is to count everyone in a rather than a fraction. However, population censuses rely on a frame to count the population. This is the way to be sure that everyone has been included as otherwise those not responding would not be followed up on. The fundamental premise of a census is that the population is not known, the use of a sampling frame is counterintuitive as it suggests that the population size is already known. However, a census is also used to collect data on the individuals in the nation. This process of sampling marks the difference between historical census, which was a house to house process or the product of a decree. The sampling frame used by census is almost always an address register, thus it is not known if there is anyone resident or how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, a particular problem is what are termed communal establishments which category includes student residences, religious orders, homes for the elderly, people in prisons etc

Population density
–
Population density is a measurement of population per unit area or unit volume, it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans and it is a key geographical term. Population density is population divided by land area or water volume. Low densities may cause a vortex and lead to further reduced fertility. This is called the Allee effect after the scientist who identified it, commonly this may be calculated for a county, city, country, another territory, or the entire world. The worlds population is around 7,000,000,000, therefore, the worldwide human population density is around 7,000,000,000 ÷510,000,000 =13.7 per km2. If only the Earths land area of 150,000,000 km2 is taken into account and this includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 50 people per km2, 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, microstates, 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, for instance, Milwaukee has a greater population density when just the inner city is measured, and the surrounding suburbs excluded. 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. S.

Poverty threshold
–
The poverty threshold, poverty limit or poverty line is the minimum level of income deemed adequate in a particular country. In practice, like the definition of poverty, the official or common understanding of the poverty line is higher in developed countries than in developing countries. In 2008, the World Bank came out with a figure of $1.25 at 2005 purchasing-power parity, the new IPL replaces the $1.25 per day figure, which used 2005 data. Most scholars agree that it better reflects todays reality, particularly new price levels in developing countries, the common international poverty line has in the past been roughly $1 a day. At present the percentage of the population living under extreme poverty is likely to fall below 10% according to the World Bank projections released in 2015. Determining the poverty line is usually done by finding the total cost of all the resources that an average human adult consumes in one year. Individual factors are used to account for various circumstances, such as whether one is a parent, elderly. The poverty threshold may be adjusted annually, charles Booth, a pioneering investigator of poverty in London at the turn of the 20th century, popularised the idea of a poverty line, a concept originally conceived by the London School Board. Booth set the line at 10 to 20 shillings per week, to secure the necessaries of a healthy life, which included fuel and light, rent, food, clothing, and household and personal items. Based on data from leading nutritionists of the period, he calculated the cheapest price for the minimum calorific intake and nutritional balance necessary and he considered this amount to set his poverty line and concluded that 27. 84% of the total population of York lived below this poverty line. Rowntree distinguished between primary poverty, those lacking in income and secondary poverty, those who had enough income, Absolute poverty is the level of poverty as defined in terms of the minimal requirements necessary to afford minimal standards of food, clothing, health care and shelter. For the measure to be absolute, the line must be the same in different countries, cultures, such an absolute measure should look only at the individuals power to consume and it should be independent of any changes in income distribution. Notice that if real income in an economy increases. Measuring poverty by a threshold has the advantage of applying the same standard across different locations and time periods. For example, a living in far northern Scandinavia requires a source of heat during colder months. The term absolute poverty is sometimes used as a synonym for extreme poverty. Absolute poverty is the absence of resources to secure basic life necessities. It depends not only on income but also on access to services, safe drinking water, Water must not come solely from rivers and ponds, and must be available nearby
