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

Population
–
A population is the number of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. In sociology, population refers to a collection of humans, Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population, in population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring and this also implies that all members belong to the same species. If the gamodeme is very large, and all gene alleles are uniformly distributed by the gametes within it, however, there may be low frequencies of exchange with these neighbours. This may be viewed as the breaking up of a sexual population into smaller overlapping sexual populations. The overall rise in homozygosity is quantified by the inbreeding coefficient, note that all homozygotes are increased in frequency – both the deleterious and the desirable. The mean phenotype of the collection is lower than that of the panmictic original – which is known as inbreeding depression. It is most important to note, however, that some lines will be superior to the panmictic original, while some will be about the same. The probabilities of each can be estimated from those binomial equations, in plant and animal breeding, procedures have been developed which deliberately utilise the effects of dispersion. It can be shown that dispersion-assisted selection leads to the greatest genetic advance and this is so for both allogamous and autogamous gamodemes. In ecology, the population of a species in a certain area can be estimated using the Lincoln Index. As of todays date, the population is estimated by the United States Census Bureau to be 7.496 billion. The US Census Bureau estimates the 7 billion number was surpassed on 12 March 2012, according to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the day on which world population reached 6 billion. This was about 12 years after world population reached 5 billion in 1987, the population of countries such as Nigeria, is not even known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have probably been born in the last 2000 years, Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. In 2007 the United Nations Population Division projected that the population will likely surpass 10 billion in 2055

Cayman Islands
–
The Cayman Islands is a British Overseas Territory in the western Caribbean Sea. Its population is approximately 60,000, and its capital is George Town, the Cayman Islands are considered to be part of the geographic Western Caribbean Zone as well as the Greater Antilles. The territory is considered a major world offshore financial haven for many wealthy individuals. The Cayman Islands remained largely uninhabited until the 17th century, the first recorded permanent inhabitant of the Cayman Islands, Isaac Bodden, was born on Grand Cayman around 1661. He was the grandson of the original settler named Bodden who was one of Oliver Cromwells soldiers at the taking of Jamaica in 1655. England took formal control of the Cayman Islands, along with Jamaica, following several unsuccessful attempts at settlement, a permanent English-speaking population in the islands dates from the 1730s. With settlement, after the first royal land grant by the Governor of Jamaica in 1734, many were brought to the islands from Africa, this is evident today with the majority of native Caymanians being of African and English descent. The results of the first census taken in the islands in 1802 showed the population on Grand Cayman to be 933 with 545 of those inhabitants being enslaved, slavery was abolished in the Cayman Islands in 1833. At the time of abolition, there were over 950 Blacks of African ancestry enslaved by 116 white families of English ancestry. The islands continued to be governed as part of the Colony of Jamaica until 1962, the Cayman Islands historically have been a tax-exempt destination. On 8 February 1794, the Caymanians rescued the crews of a group of ten merchant ships, including HMS Convert, the ships had struck a reef and run aground during rough seas. Legend has it that King George III rewarded the island with a never to introduce taxes as compensation for their generosity. While this remains a legend, the story is not true. However, whatever the history, in practice the government of the Cayman Islands has always relied on indirect, the islands have never levied income tax, capital gains tax, or any wealth tax, making them a popular tax haven. On 11 September 2004 the island of Grand Cayman, which lies largely unprotected at sea level, was hit by Hurricane Ivan, an estimated 83% of the dwellings on the island were damaged including 4% requiring complete reconstruction. A reported 70% of all dwellings suffered severe damage from flooding or wind, another 26% sustained minor damage from partial roof removal, low levels of flooding, or impact with floating or wind driven hurricane debris. Power, water and communications were disrupted for months in areas as Ivan was the worst hurricane to hit the islands in 86 years. Grand Cayman began a rebuilding process and within two years its infrastructure was nearly returned to pre-hurricane status.23 years

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.

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 United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

Canada
–
Canada is a country in the northern half of North America. Canadas border with the United States is the worlds longest binational land border, the majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its territory being dominated by forest and tundra. It is highly urbanized with 82 per cent of the 35.15 million people concentrated in large and medium-sized cities, One third of the population lives in the three largest cities, Toronto, Montreal and Vancouver. Its capital is Ottawa, and other urban areas include Calgary, Edmonton, Quebec City, Winnipeg. Various aboriginal peoples had inhabited what is now Canada for thousands of years prior to European colonization. Pursuant to the British North America Act, on July 1,1867, the colonies of Canada, New Brunswick and this began an accretion of provinces and territories to the mostly self-governing Dominion to the present ten provinces and three territories forming modern Canada. With the Constitution Act 1982, Canada took over authority, removing the last remaining ties of legal dependence on the Parliament of the United Kingdom. Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level and it is one of the worlds most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources, Canadas long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a country and has the tenth highest nominal per capita income globally as well as the ninth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, Canada is an influential nation in the world, primarily due to its inclusive values, years of prosperity and stability, stable economy, and efficient military. While a variety of theories have been postulated for the origins of Canada. In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona, from the 16th to the early 18th century Canada referred to the part of New France that lay along the St. Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named The Canadas, until their union as the British Province of Canada in 1841. Upon Confederation in 1867, Canada was adopted as the name for the new country at the London Conference. The transition away from the use of Dominion was formally reflected in 1982 with the passage of the Canada Act, later that year, the name of national holiday was changed from Dominion Day to Canada Day

Honduras
–
Honduras, officially the Republic of Honduras, is a republic in Central America. It has at times referred to as Spanish Honduras to differentiate it from British Honduras. Honduras was home to several important Mesoamerican cultures, most notably the Maya, the Spanish introduced Roman Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras has the worlds highest murder rate, Honduras spans about 112,492 km2 and has a population exceeding 8 million. Its northern portions are part of the Western Caribbean Zone, as reflected in the areas demographics and culture. Honduras is known for its natural resources, including minerals, coffee, tropical fruit, and sugar cane, as well as for its growing textiles industry. Honduras literally means depths in Spanish, the name could either refer to the bay of Trujillo as an anchorage, fondura in the Leonese dialect of Spanish, or to Columbuss alleged quote that Gracias a Dios que hemos salido de esas Honduras. It was not until the end of the 16th century that Honduras was used for the whole province, prior to 1580, Honduras only referred to the eastern part of the province, and Higueras referred to the western part. Another early name is Guaymuras, revived as the name for the dialogue in 2009 that took place in Honduras as opposed to Costa Rica. In pre-Columbian times, modern Honduras was part of the Mesoamerican cultural area, in the west, the Maya civilization flourished for hundreds of years. The dominant state within Hondurass borders was in Copán, Copán fell with the other Lowland centres during the conflagrations of the Terminal Classic in the 9th century. The Maya of this civilization survive in western Honduras as the Chorti, remains of other Pre-Columbian cultures are found throughout the country. On 30 July 1502 Columbus sent his brother Bartholomew to explore the islands and Bartholomew encountered a Mayan trading vessel from Yucatán, carrying well-dressed Maya and a rich cargo. Bartholomews men stole whatever cargo they wanted and kidnapped the elderly captain to serve as an interpreter in what was the first recorded encounter between the Spanish and the Maya. In March 1524, Gil González Dávila became the first Spaniard to enter Honduras as a conquistador, followed by Hernán Cortés, bringing forces down from Mexico. Much of the conquest was done in the two decades, first by groups loyal to Cristóbal de Olid, and then by those loyal of Francisco Montejo. In addition to Spanish resources, the conquerors relied heavily on armed forces from Mexico—Tlaxcalans, resistance to conquest was led in particular by Lempira, and many regions in the north never fell to the Spanish, notably the Miskito Kingdom. After the Spanish conquest, Honduras became part of Spains vast empire in the New World within the Kingdom of Guatemala, Trujillo and Gracias were the first city-capitals
