Isolation Index
An isolation index is a measure of the segregation of the activities of multiple populations. They have been used in studies of racial segregation and ideological segregation. Examples of isolation indices include Lieberson's isolation index and Bell's isolation index.

Population
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with in ...

Racial Segregation
Racial segregation is the systematic separation of people into race (human classification), racial or other Ethnicity, ethnic groups in daily life. Racial segregation can amount to the international crime of apartheid and a crimes against humanity, crime against humanity under the Statute of the International Criminal Court. Segregation can involve the wikt:spatial, spatial separation of the races, and mandatory use of different institutions, such as schools and hospitals by people of different races. Specifically, it may be applied to activities such as eating in restaurants, drinking from water fountains, using public toilets, attending schools, going to films, riding buses, renting or purchasing homes or renting hotel rooms. In addition, segregation often allows close contact between members of different racial or ethnic groups in social hierarchy, hierarchical situations, such as allowing a person of one race to work as a servant for a member of another race.

Ideological Segregation
An ideology is a set of beliefs or philosophies attributed to a person or group of persons, especially those held for reasons that are not purely epistemic, in which "practical elements are as prominent as theoretical ones." Formerly applied primarily to economic, political, or religious theories and policies, in a tradition going back to Karl Marx and Friedrich Engels, more recent use the term as mainly condemnatory. The term was coined by Antoine Destutt de Tracy, a French Enlightenment aristocrat and philosopher, who conceived it in 1796 as the "science of ideas" to develop a rational system of ideas to oppose the irrational impulses of the mob. In political science, the term is used in a descriptive sense to refer to political belief systems. Etymology and history The term ''ideology'' originates from French ''idéologie'', itself deriving from combining (; close to the Lockean sense of ''idea'') and '' -logíā'' (). The term ideology, and the system of ideas associated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieberson's Isolation Index
An index of qualitative variation (IQV) is a measure of statistical dispersion in nominal distributions. There are a variety of these, but they have been relatively little-studied in the statistics literature. The simplest is the variation ratio, while more complex indices include the information entropy. Properties There are several types of indices used for the analysis of nominal data. Several are standard statistics that are used elsewhere - range, standard deviation, variance, mean deviation, coefficient of variation, median absolute deviation, interquartile range and quartile deviation. In addition to these several statistics have been developed with nominal data in mind. A number have been summarized and devised by Wilcox , , who requires the following standardization properties to be satisfied: * Variation varies between 0 and 1. * Variation is 0 if and only if all cases belong to a single category. * Variation is 1 if and only if cases are evenly divided across all cat ...

Bell's Isolation Index
Bell's is a brand of blended Scotch whisky produced by Diageo in Scotland. It was originally produced by Arthur Bell & Sons Ltd. It is the best selling whisky in the UK. History The Bells distillery was founded in 1798. In 1851, Arthur Bell (1825–1900) began to blend various single malts together to create a more consistent blended whisky. Arthur Bell was the first known whisky manufacturer to appoint a London agent, by at least 1863. Bell's two sons joined the business in partnership in 1895. Arthur Kinmond (1868–1942) was appointed to manage the domestic market and Robert was appointed as head of the brand overseas. By the 1880s the company was focused on blended whisky. Arthur Bell died in 1900. In 1921 the partnership became a private company run by Arthur Kinmond after Robert retired to live as a country gentleman. The end of Prohibition in America created a surge in demand, which led Arthur Bell & Sons to acquire two distilleries in 1933: Blair Athol and Dufftown. ...

Diversity Index
A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community), and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as ''richness'', ''divergence'' or ''evenness''. These indices are statistical representations of biodiversity in different aspects ( richness, evenness, and dominance). Effective number of species or Hill numbers When diversity indices are used in ecology, the types of interest are usually species, but they can also be other categories, such as genera, families, functional types, or haplotypes. The entities of interest are usually individual plants or animals, and the measure of abundance can be, for example, number of individuals, biomass or coverage. In demography, the entities of interest can be people, and the types of interest various demographic groups. In information science, the entities can be chara ...

Index Of Dissimilarity
The index of dissimilarity is a demographic measure of the evenness with which two groups are distributed across component geographic areas that make up a larger area. A group is evenly distributed when each geographic unit has the same percentage of group members as the total population. The index score can also be interpreted as the percentage of one of the two groups included in the calculation that would have to move to different geographic areas in order to produce a distribution that matches that of the larger area. The index of dissimilarity can be used as a measure of segregation. A score of zero (0%) reflects a fully integrated environment; a score of 1 (100%) reflects full segregation. In terms of black–white segregation, a score of .60 means that 60 percent of blacks would have to exchange places with whites in other units to achieve an even geographic distribution. Basic formula The basic formula for the index of dissimilarity is: :D = \frac \sum_^N \left, \frac - ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demography
Demography () is the statistics, statistical study of populations, especially human beings. Demographic analysis examines and measures the dimensions and Population dynamics, dynamics of populations; it 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. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of Social actions, social actors can change across time through processes of birth, death, and Human migration, migration. In the context of human biological populations, demographic analysis uses Public records, administrative records to develop an independent Approximation, estimate of the population.
