A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area. The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border.
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 such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same of species, such as humans. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.

In astronomy and physical cosmology, the metallicity or Z is the fraction of mass of a star or other kind of astronomical object that is not in hydrogen (X) or helium (Y). Most of the physical matter in the universe is in the form of hydrogen and helium, so astronomers use the word "metals" as a convenient short term for "all elements except hydrogen and helium". This usage is distinct from the usual physical definition of a solid metal. The astronomical usage is claimed to be justified because in the high-temperature and pressure environment of a star, atoms do not undergo chemical reactions and effectively have no chemical properties, including that of being a metal as usually understood. For example, stars and nebulae with relatively high abundances of carbon, nitrogen, oxygen, and neon are called "metal-rich" in astrophysical terms, even though those elements are non-metals in chemistry.
The distinction between hydrogen and helium on the one hand and metals on the other is relevant because the primordial universe is believed to have contained virtually no metals, which were later synthesised within stars.
American English, or United States (U.S.) English, is the set of dialects of the English language native to the United States. English is the most widely spoken language in the United States and is the common language used by the federal government, considered the de facto language of the country because of its widespread use. English has been given official status by 30 of the 50 state governments. As an example, while both Spanish and English have equivalent status in the local courts of the Commonwealth of Puerto Rico, under federal law, English is the official language for any matters being referred to the United States District Court for the territory.
The use of English in the United States is a result of British colonization. The first wave of English-speaking settlers arrived in North America during the 17th century, followed by further migrations in the 18th and 19th centuries. Since then, American English has been influenced by the languages of West Africa, the Native American population, German, Dutch, Irish, Spanish, and other languages of successive waves of immigrants to the United States.

A drama with slight tinges of black humour and satire, the film stars Jayasurya, Nivin Pauly, Mukesh, Nadia Moidu, Remya Nambeesan. The film is produced by Binu Dev under the banner of Navarang Screens and features music composed by Rex Vijayan of the band Avial, whilst cinematography is handled by Udayan Ambaadi and is edited by Vinod Sukumaran. The film tells the story of the lives of the Malayalees living in London.
The lives of four characters from diverse backgrounds whose passage to the U.K. and its aftermath are dealt with in the film. Jayasurya plays Shankaran, a Kathakali artiste-turned-waiter who is an illegal immigrant. Nivin Pauly dons the role of Sibin, an IT executive with a roving eye. Mukesh plays Joy, a middle-class corner store owner with an extended family in London and all its concomitant problems and advantages. Nadia Moidu plays Saraswathy, a Tamil Brahmin. Married to a doctor, she has been in the U.K, for more than 20 years. Remya Nambeesan plays Gauri, a young married woman from a rustic background who arrives in London.
Pakistani English or Paklish is the group of English language varieties spoken and written in Pakistan. It was first so recognised and designated in the 1970s and 1980s. Pakistani English (PE) is slightly different in respect to vocabulary, syntax, accent, spellings of some words and other features. Approximately 49% of the Pakistani population is able to communicate to an intermediate level of English.
Although British rule in India lasted for almost two hundred years, the areas which lie in what is now Pakistan were amongst the last to be annexed: Sindh in 1843, Punjab (which initially included the North-West Frontier Province) in 1849, and parts of Baluchistan, including Quetta and the outer regions in 1879, while the rest of the Baluchistan region became a princely state within the British Indian Empire. As a result English had less time to become part of local culture though it did become part of elitist culture as it was used in elite schools and in higher education, as in the rest of British India. The colonial policies which made English a marker of elite status and the language of power—being used in such domains of power as the civil service, the officer corps of the armed forces, the higher judiciary, universities, prestigious newspapers, radio and entertainment—was due to British policies and the continuation of these policies by Pakistani governments. In 1947 upon Pakistan's establishment, English became the de facto official language, a position which was formalised in the Constitution of Pakistan of 1973. Together with Urdu, the two languages are concurrently the official languages of the country. English language continues as the language of power and is also the language with the maximum cultural capital of any language used in Pakistan. It remains much in demand in higher education in Pakistan.
