Demography
–
Demography is the statistical study of populations, especially human beings. As a very general science, it can analyse any kind of dynamic living population, Demography encompasses the study of the size, structure, and distribution of these populations, and spatial or temporal changes in them in response to birth, migration, ageing, and death. Based on the research of the earth, earths population up to the year 2050 and 2100 can be estimated by demographers. Demographics are quantifiable characteristics of a given population, demographic analysis can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments, demographic thoughts can be traced back to antiquity, and were present in many civilizations and cultures, like Ancient Greece, Ancient Rome, India and China. In ancient Greece, this can be found in the writings of Herodotus, Thucidides, Hippocrates, Epicurus, Protagoras, Polus, Plato and Aristotle. In Rome, writers and philosophers like Cicero, Seneca, Pliny the elder, Marcus Aurelius, Epictetus, Cato, in the Middle ages, Christian thinkers devoted much time in refuting the Classical ideas on demography. Important contributors to the field were William of Conches, Bartholomew of Lucca, William of Auvergne, William of Pagula, and Ibn Khaldun. One of the earliest demographic studies in the period was Natural and Political Observations Made upon the Bills of Mortality by John Graunt. Among the studys findings were that one third of the children in London died before their sixteenth birthday, mathematicians, such as Edmond Halley, developed the life table as the basis for life insurance mathematics. Richard Price was credited with the first textbook on life contingencies published in 1771, followed later by Augustus de Morgan, at the end of the 18th century, Thomas Robert Malthus concluded that, if unchecked, populations would be subject to exponential growth. He feared that population growth would tend to outstrip growth in production, leading to ever-increasing famine. He is seen as the father of ideas of overpopulation. Later, more sophisticated and realistic models were presented by Benjamin Gompertz, the period 1860-1910 can be characterized as a period of transition wherein demography emerged from statistics as a separate field of interest. There are two types of data collection—direct and indirect—with several different methods of each type, direct data comes from vital statistics registries that track all births and deaths as well as certain changes in legal status such as marriage, divorce, and migration. In developed countries with good registration systems, registry statistics are the best method for estimating the number of births and deaths, a census is the other common direct method of collecting demographic data. A census is conducted by a national government and attempts to enumerate every person in a country. Analyses are conducted after a census to estimate how much over or undercounting took place and these compare the sex ratios from the census data to those estimated from natural values and mortality data

American Samoa
–
American Samoa is an unincorporated territory of the United States located in the South Pacific Ocean, southeast of Samoa. American Samoa consists of five islands and two coral atolls. The largest and most populous island is Tutuila, with the Manuʻa Islands, Rose Atoll, All islands except for Swains Island are part of the Samoan Islands, located west of the Cook Islands, north of Tonga, and some 300 miles south of Tokelau. To the west are the islands of the Wallis and Futuna group, the 2010 census showed a total population of 55,519 people. The total land area is 199 square kilometers, slightly more than Washington, American Samoa is the southernmost territory of the U. S. and one of two U. S. territories south of the Equator, along with the uninhabited Jarvis Island. Tuna products are the exports, and the main trading partner is the United States. American Samoa is noted for having the highest rate of enlistment of any U. S. state or territory. Most American Samoans are bilingual and can speak English and Samoan fluently, Samoan is the same language spoken in neighboring independent Samoa. Contact with Europeans began in the early 18th century, dutchman Jacob Roggeveen was the first known European to sight the Samoan Islands in 1722. This visit was followed by French explorer Louis-Antoine de Bougainville who named them the Navigator Islands in 1768, contact was limited before the 1830s, when English missionaries and traders began arriving. The site of battle is called Massacre Bay. Mission work in the Samoas had begun in late 1830 when John Williams of the London Missionary Society arrived from the Cook Islands, by that time, the Samoans had gained a reputation for being savage and warlike, as violent altercations had occurred between natives and European visitors. In March 1889, an Imperial German naval force entered a village on Samoa, three American warships then entered the Apia harbor and prepared to engage the three German warships found there. Before any shots were fired, a typhoon wrecked both the American and German ships, a compulsory armistice was then called because of the lack of any warships. Forerunners to the Tripartite Convention of 1899 were the Washington Conference of 1887, the Treaty of Berlin of 1889, the following year, the USA formally occupied its portion, a smaller group of eastern islands, one of which contains the noted harbor of Pago Pago. The Navy secured a Deed of Cession of Tutuila in 1900, the territory became known as the US Naval Station Tutuila. On July 17,1911, the US Naval Station Tutuila, in 1918 during the final stages of World War I, the flu pandemic had taken its toll, spreading rapidly from country to country. The result of Poyers quick actions earned him the Navy Cross from the US Navy, with this distinction, American Samoans regarded Poyer as their hero for what he had done to prevent the deadly disease

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. States by population density Selected Current and Historic City, Ward & Neighborhood Density

Ethnic group
–
An ethnic group or ethnicity is a category of people who identify with each other based on similarities, such as common ancestral, language, social, cultural or national experiences. Unlike other social groups, ethnicity is often an inherited status based on the society in which one lives, in some cases, it can be adopted if a person moves into another society. Ethnic groups, derived from the historical founder population, often continue to speak related languages. By way of language shift, acculturation, adoption and religious conversion, it is possible for individuals or groups to leave one ethnic group. Ethnicity is often used synonymously with terms such as nation or people. In English, it can also have the connotation of something exotic, generally related to cultures of more recent immigrants, the largest ethnic groups in modern times comprise hundreds of millions of individuals, while the smallest are limited to a few dozen individuals. Conversely, formerly separate ethnicities can merge to form a pan-ethnicity, whether through division or amalgamation, the formation of a separate ethnic identity is referred to as ethnogenesis. The term ethnic is derived from the Greek word ἔθνος ethnos, the inherited English language term for this concept is folk, used alongside the latinate people since the late Middle English period. In Early Modern English and until the mid-19th century, ethnic was used to mean heathen or pagan, as the Septuagint used ta ethne to translate the Hebrew goyim the nations, non-Hebrews, non-Jews. The Greek term in antiquity could refer to any large group, a host of men. In the 19th century, the term came to be used in the sense of peculiar to a race, people or nation, the abstract ethnicity had been used for paganism in the 18th century, but now came to express the meaning of an ethnic character. The term ethnic group was first recorded in 1935 and entered the Oxford English Dictionary in 1972, depending on the context that is used, the term nationality may either be used synonymously with ethnicity, or synonymously with citizenship. The process that results in the emergence of an ethnicity is called ethnogenesis, the Greeks at this time did not describe foreign nations but had also developed a concept of their own ethnicity, which they grouped under the name of Hellenes. Herodotus gave an account of what defined Greek ethnic identity in his day, enumerating shared descent. Whether ethnicity qualifies as a universal is to some extent dependent on the exact definition used. Many social scientists, such as anthropologists Fredrik Barth and Eric Wolf and they regard ethnicity as a product of specific kinds of inter-group interactions, rather than an essential quality inherent to human groups. According to Thomas Hylland Eriksen, the study of ethnicity was dominated by two distinct debates until recently, one is between primordialism and instrumentalism. In the primordialist view, the participant perceives ethnic ties collectively, as a given, even coercive

The World Factbook
–
The World Factbook is a reference resource produced by the Central Intelligence Agency with almanac-style information about the countries of the world. The official print version is available from the National Technical Information Service, Other companies—such as Skyhorse Publishing—also print a paper edition. The Factbook is available in the form of a website that is updated every week. It is also available for download for use off-line, the World Factbook is prepared by the CIA for the use of U. S. Government officials, and its style, format, coverage, and content are primarily designed to meet their requirements. However, it is used as a resource for academic research papers. As a work of the U. S. Government, it is in the domain in the United States. In researching the Factbook, the CIA uses the sources listed below, Other public and private sources are also consulted. However, the CIA requests that it be cited when the Factbook is used, copying the official seal of the CIA without permission is prohibited by U. S. federal law—specifically, the Central Intelligence Agency Act of 1949. Before November 2001 The World Factbook website was updated yearly, from 2004 to 2010 it was updated every two weeks, since 2010 it has been updated weekly, generally, information currently available as of January 1 of the current year is used in preparing the Factbook. The first, classified, edition of Factbook was published in August 1962, the World Factbook was first available to the public in print in 1975. In 2008 the CIA discontinued printing the Factbook themselves, instead turning printing responsibilities over to the Government Printing Office and this happened due to a CIA decision to focus Factbook resources on the online edition. The Factbook has been on the World Wide Web since October 1994, the web version gets an average of 6 million visits per month, it can also be downloaded. The official printed version is sold by the Government Printing Office, in past years, the Factbook was available on CD-ROM, microfiche, magnetic tape, and floppy disk. Many Internet sites use information and images from the CIA World Factbook, several publishers, including Grand River Books, Potomac Books, and Skyhorse Publishing have re-published the Factbook in recent years. As of July 2011, The World Factbook consists of 267 entities and these entities can be divided into categories. They are, Independent countries This category has independent countries, which the CIA defines as people politically organized into a state with a definite territory. In this category, there are 195 entities, others The Other category is a list of other places set apart from the list of independent countries. Currently there are two, Taiwan and the European Union, dependencies and Areas of Special Sovereignty This category is a list of places affiliated with another country

Population pyramid
–
This tool can be used to visualize sex and age composition of a particular population. It is also used in ecology to determine the age distribution of a population. Population pyramid often contains continuous stacked-histogram bars, the population size is depicted on the x-axis, and age-groups on y-axis. Males are conventionally shown on the left and females on the right, population pyramids are often viewed as the most effective way to graphically depict the age and sex distribution of a population, partly because of the very clear image these pyramids represent. A population pyramid also tells how people of each age range live in the area. There tends to be more females than males in the age groups. Population pyramid gives a picture of how a country transitions from high fertility to low fertility rate. The population pyramid here indicates stage 3 on the demographic transition, the broad base of the pyramid means the majority of population lies between ages 0-14, which tells us that the fertility rate of the country is high and above population Sub-replacement fertility. There is a dependency ratio of younger population over the working population. Moreover, there is lesser older population due to life expectancy which is around 60 years. Each country will have different or unique population pyramids, however, most population pyramids will be defined as the following, Stationary, expansive, or constrictive. These types have been identified by the fertility and mortality rates of a country, constrictive pyramid A population pyramid that is narrowed at the bottom. This pyramid is more common, especially when immigrants are factored out. This is a pattern for a very developed country, a high level of education, easy access to and incentive to use birth control, good health care. Gary Fuller described Youth bulge as a type of expansive pyramid and this factor has been also used to account for the Arab Spring events. Economic recessions, such as the Great Depression of the 1930s, Youth bulge can be seen as one factor among many in explaining social unrest and uprisings in society. A2016 study finds that youth bulges increases the chances of non-ethnic civil wars, a large population of adolescents entering the labor force and electorate strains at the seams of the economy and polity, which were designed for smaller populations. Yet the 16–30 age range is associated with risk-taking, especially among males, in general, youth bulges in developing countries are associated with higher unemployment and, as a result, a heightened risk of violence and political instability

Pacific Islander
–
Pacific Islander is a term used to refer to the peoples of the Pacific Islands. According to the Encyclopædia Britannica, the Pacific islands consist of three regions, The islands scattered across a triangle covering the region of the Pacific Ocean. The triangle is bound by the Hawaiian Islands in the north, New Zealand in the west, the rest of Polynesia includes the Samoan islands, the Cook Islands, French Polynesia, Niue Island, Tokelau and Tuvalu, Tonga, Wallis and Futuna, and Pitcairn Island. The islands of Kiribati, Nauru, the Marianas, the Republic of the Marshall Islands, Palau, the Pacific islands may also refer to any of the other islands in the Pacific Ocean. Ethnolinguistically, those Pacific islanders who reside in Oceania are divided into two different ethnic classifications, Austronesian language peoples Austronesian peoples who speak the Oceanian languages, numbering about 2.3 million, who occupy Polynesia, Micronesia, and most of the smaller islands of Melanesia. The Pacific Island Labourers Act 1901 was enacted to restrict entry of Pacific Islanders to Australia, in 2008 a Pacific Seasonal Worker Pilot Scheme was announced as a three-year pilot scheme. The scheme provides visas for workers from Kiribati, Tonga, Vanuatu, the pilot scheme includes one country each from Melanesia, Polynesia and Micronesia, countries which already send workers to New Zealand under its seasonal labour scheme. Australias pilot scheme also includes Papua New Guinea, in 20137.4 percent of the New Zealand population identified with one or more Pacific ethnic groups, although 62.3 percent of these were born in New Zealand. Those with a Samoan background make up the largest proportion, followed by Cook Islands Maori, Tongan, some smaller island populations such as Niue and Tokelau have the majority of their nationals living in New Zealand. To celebrate the diverse Pacific island cultures, the Auckland region hosts several Pacific island festivals and it includes people who indicate their race as Native Hawaiian, Guamanian or Chamorro, Samoan, and Other Pacific Islander or provide other detailed Pacific Islander responses.

Samoans
–
The Samoan people are a Polynesian ethnic group of the Samoan Islands, sharing genetics, language, history and culture. Samoans living in Samoa in 2006 were estimated at 188,000, the majority of ethnic Samoans now reside in other countries, primarily in the United States, New Zealand and Australia. This approximation is based on the Lapita pottery that has dated to that time. Furthermore, the Samoans have developed a language, culture, and social practice most divergent from the ethnic groups associated with the Lapita pottery. Early contact with Europeans was established in the 18th century, christianity was formally introduced with the arrival of L. M. S. During the early 20th century the Samoan Islands were partitioned by Germany, Great Britain, tutuila and Aunuu islands were claimed by the USA and later joined by the Kingdom of Manua to become the current Territory of American Samoa. The western islands became German Samoa, in 1914, New Zealand forces captured the islands from Germany, thus becoming Western Samoa. Western Samoa regained its independence on January 1,1962, in 1997 it formally changed its name to Samoa. Traditional Samoan tattoo, pea, malu, demonstrate the strong ties many Samoans feel for their culture, Samoans have practiced the art of tattooing men and women for over 2,000 years. To this day, a mans tattoo extensively covers from mid-back, down the sides and flanks, a womans tattoo is not as extensive or heavy. The geometric patterns are based on ancient designs that often denote rank, the vaa, for example, stretches across a mans mid-back. Samoan oral tradition generally recognizes that two Fijian women, Taema and Tilafaiga, introduced the practice of tattooing, before the arrival of Christian missionaries, starting in 1830, all Samoan males got a traditional tattoo. Though the early missionaries did not succeed in outlawing the practice, in Samoas cultural past most males were tattooed between the ages of 14–18, when it was determined they had stopped growing, so the designs would not stretch and suffer in beauty. Today, there has been a revival of traditional tattooing in the past generation, not only in Samoa but throughout Polynesia. Tatau, the Samoan word for tattoo has a number of meanings including correct or rightness and it also signifies the correct quadrangular figures in reference to the fact that Samoan tattoo designs do not include circular lines, although other Polynesian tattoo motifs do. Early Englishmen mispronounced the word tatau and borrowed it into popular usage as tattoo, traditional tattooing is a painful process. The Samoan tattoo master dips his cutting tools into black ink made from the soot of burnt candlenut shells, the cutting tool consists of a short piece of bamboo or light wood with a piece of tortoiseshell bound at right angles at one end. A little bone comb is bound to the broad end of the tortoiseshell

Demographics of Tonga
–
Almost two-thirds of the population of the Kingdom of Tonga live on its main island, Tongatapu. Other important Christian denominations include Methodists and Roman Catholics, tongans, a Polynesian group with a very small mixture of Melanesian, represent more than 98% of the inhabitants. The rest are European, mixed European, and other Pacific Islanders, there also are several hundred Chinese. Primary education between ages 6 and 14 is compulsory and free in state schools, mission schools provide about 83% of the primary and 90% of the secondary level education. Higher education includes teacher training, nursing and medical training, a private university, a womens business college. Most higher education is pursued overseas, according to the CIA factbook on Tonga the population is 96. 6% fully Tongan. Based on 2006 estimates the religious breakdown of the population was Protestant 64. 9%, Latter-day Saints 16. 8%, Roman Catholic 15. 6%, other 1. 1%, none 0. 03%, unspecified 1. 7%. As the 1960s ended the growth rate fell very fast in the country. In the 1930s Tonga had a population of about 32,000, starting in the 1970s large scale migration began to Australia and New Zealand. By the 1970s the out-migration rate from Tonga to Australia, New Zealand and the United States was at a rate of over 2% annually
