Camargo Municipality, Tamaulipas
Camargo is a municipality in the Mexican state of Tamaulipas. It is located on the US border, across from Texas, it has an official population of an international bridge. The municipal seat is Ciudad Camargo, with a population of 7,984; the municipality is connected to Rio Grande City, Texas via the Rio Grande City-Camargo International Bridge. The first settlement to be founded on the Lower Río Grande was that of Nuestra Señora de Santa Ana de Camargo, it was founded on March 5, 1749, with the dedication to Señora Santa Ana by captain Don Blas María de la Garza Falcón at the eastern edge of the San Juan River near its confluence with the Río Grande. The foundation had 85 families – a total of 531 persons. Most of the settlers for this township came from Cerralvo, Cadereyta and surrounding townships. After establishing other towns in the interior of Mexico between Querétaro and the Gulf coast, José de Escandón arrived at Camargo on March 3, 1749. At the location called, "Paso del Azucar" on the Rio Grande, about two leagues southeast of the present site of Camargo, he met Captain Blas Maria de la Garza Falcón, encamped there with forty other families and some soldiers.
In the group led by Captain Blas Maria de la Garza Falcon were Miguel de la Garza Falcon, his brother, Nicolas de los Santos Coy, father-in-law of Captain Falcon and ex-alcalde of nearby Cerralvo Municipality in Nuevo León. These settlers were men of wealth; the town had been laid out on the eastern bank of the San Juan River, not far from the Rio Grande, temporary shelters made, jacales. Father Fray Hierro, who had joined Escandon at Padilla and was a missionary from the college of Zacatecas, kept a diary which provides many interesting details concerning the establishment of the first settlements of the Lower Rio Grande Valley. Fourteen settlements were established in a six months period; the settlers of this town were, as is evident from the captain's registry Spaniards. A great flood in the year 1751 did some damage to the settlement, for which reason it was moved a little farther down the river to a higher site. An irrigation canal, built at the original location, because of their not having trimmed the opening to the canal with stone and mortar, was destroyed by the flood.
On July 14, 1846, Camargo was occupied by the US Army under the command of General Zachary Taylor. This river port served as a jumping off point for the invasion on Saltillo; the US Army was transported via steamboats from the mouth of the river area, Matamoros. Disease plagued the troops and it is said that thousand of US soldiers were buried here, in unmarked graves; the largest localities are: Gustavo Díaz Ordaz Municipality - southeast General Bravo Municipality, Nuevo León - southeast Doctor Coss Municipality, Nuevo León - southwest Miguel Alemán Municipality - northwest Rio Grande City, Texas - north
A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; 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: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with 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 fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
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, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits.

The American frontier comprises the geography, history and cultural expression of life in the forward wave of American expansion that began with English colonial settlements in the early 17th century and ended with the admission of the last mainland territories as states in 1912. A "frontier" is a zone of contact at the edge of a line of settlement; the leading theorist Frederick Jackson Turner went deeper, arguing that the frontier was the defining process of American civilization: "The frontier," he asserted, "promoted the formation of a composite nationality for the American people." He theorized it was a process of development: "This perennial rebirth, this fluidity of American life, this expansion westward...furnish the forces dominating American character." Turner's ideas since 1893 have inspired generations of historians to explore multiple individual American frontiers, but the popular folk frontier concentrates on the conquest and settlement of Native American lands west of the Mississippi River, in what is now the Midwest, the Great Plains, the Rocky Mountains, the Southwest, the West Coast.
In 19th- and early 20th-century media, enormous popular attention was focused on the Western United States in the second half of the 19th century, a period sometimes called the "Old West" or the "Wild West". Such media exaggerated the romance and chaotic violence of the period for greater dramatic effect; this inspired the Western genre of film, which spilled over into television shows and comic books, as well as children's toys and costumes. This era of massive migration and settlement was encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist philosophy known as "Manifest destiny"; as defined by Hine and Faragher, "frontier history tells the story of the creation and defense of communities, the use of the land, the development of markets, the formation of states." They explain, "It is a tale of conquest, but one of survival and the merging of peoples and cultures that gave birth and continuing life to America." Through treaties with foreign nations and native tribes, political compromise, military conquest, establishment of law and order, the building of farms and towns, the marking of trails and digging of mines, the pulling in of great migrations of foreigners, the United States expanded from coast to coast, fulfilling the dreams of Manifest Destiny.
Turner, in his "Frontier Thesis", theorized that the frontier was a process that transformed Europeans into a new people, the Americans, whose values focused on equality and optimism, as well as individualism, self-reliance, violence. As the American frontier passed into history, the myths of the West in fiction and film took a firm hold in the imagination of Americans and foreigners alike. In David Murdoch's view, America is exceptional in choosing its iconic self-image: "No other nation has taken a time and place from its past and produced a construct of the imagination equal to America's creation of the West." The frontier line was the outer line of European-American settlement. It moved westward from the 1630s to the 1880s. Turner favored the Census Bureau definition of the "frontier line" as a settlement density of two people per square mile; the "West" was the settled area near that boundary. Thus, parts of the Midwest and American South, though no longer considered "western", have a frontier heritage along with the modern western states.
In the 21st century, the term "American West" is most used for the area west of the Great Plains. In the colonial era, before 1776, the west was of high priority for politicians; the American frontier began when Jamestown, Virginia was settled by the English in 1607. In the earliest days of European settlement of the Atlantic coast, until about 1680, the frontier was any part of the interior of the continent beyond the fringe of existing settlements along the Atlantic coast. English, French and Dutch patterns of expansion and settlement were quite different. Only a few thousand French migrated to Canada. Although French fur traders ranged through the Great Lakes and mid-west region they settled down. French settlement was limited to a few small villages such as Kaskaskia, Illinois as well as a larger settlement around New Orleans; the Dutch set up fur trading posts in the Hudson River valley, followed by large grants of land to rich landowning patroons who brought in tenant farmers who created compact, permanent villages.
They created a dense rural settlement in upstate New York. Areas in the north that were in the frontier stage by 1700 had poor transportation facilities, so the opportunity for commercial agriculture was low; these areas remained in subsistence agriculture, as a result by the 1760s these societies were egalitarian, as explained by historian Jackson Turner Main: The typical frontier society therefore was one in which class distinctions were minimized. The wealthy speculator, if one was involved remained at home, so that ordinarily no one of wealth was a resident; the class of landless poor was small. The great majority were landowners, most of whom were poor because they were starting with little property and had not yet cleared much land nor had they acquired the farm tools and animals which would one day ma
