Index of dissimilarity

The Index of Dissimilarity is used to compare the distribution of two variables, especially in different social or ethnic groups. The data MUST be in % form and the total of each column MUST be 100%. The index of dissimilarity ID is given by the formula above where x and y are values of each sample. The dissimilarity measure d L 2 0 can be considered as the continuous form of an error index based on the sum of squared deviations [40,91], bounded between 0 and 1. On the other hand, d L 2 1 compares the deviations on the derivatives, thus it considers as perfectly similar two functions that differ only by a vertical translation:

The Article investigated many different potential measurements of segregation and concluded that the Index of Dissimilarity, also known as the Duncan Segregation Index, was the best measure of occupational segregation. Despite its imperfections, since Duncan and Duncan (1955) the index of dissimilarity has been and remains the most widely-used measure of the evenness dimension and no other index has achieved such widespread acceptance as a summary statistic of segregation. 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. 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 Index of dissimilarity is generally used to describe the (un-)evenness with which two mutually exclusive populations are distributed across all sub-divisions of a given geographic area. For instance, the index of dissimilarity quantifies the magnitude of inequality between the distribution of teachers and the distribution of pupils across provinces in a given country. When measuring segregation between two groups, the entropy index and the dissimilarity index are highly correlated, so Theil's index has generally been applied whenever investigators seek to measure segregation between multiple groups, or to decompose segregation into analytic components.

The Dissimilarity Index is a measure of the evenness with which two groups are distributed across the geographic units that make up a larger area of study, 

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. 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. dissimilarity, index of A statistic used to measure the overall difference between two percentage distributions. It is calculated by summing the differences between the numbers in each pair of corresponding values and dividing by 2. The dissimilarity index measures the relative separation or integration of groups across all neighborhoods of a city or metropolitan area. If a city's white-black dissimilarity index were 65, that would mean that 65% of white people would need to move to another neighborhood to make whites and blacks evenly distributed across all neighborhoods. The index of dissimilarity is a demographic measure of the evenness with which two groups are distributed across the component geographic areas that make up a larger area.

Index of dissimilarity is generally used to describe the (un-)evenness with which two mutually exclusive populations are distributed across all sub-divisions of a given geographic area. For instance, the index of dissimilarity quantifies the magnitude of inequality between the distribution of teachers and the distribution of pupils across provinces in a given country. The Index of Dissimilarity is the most common measure of segregation. Although it has limitations, it is relatively easy to calculate and to interpret.

Economics in Many Lessons 1,380 views Index of Dissimilarity The dissimilarity index measures whether one particular group is distributed across census tracts in the metropolitan area in the same way as another group. A high value indicates that the two groups tend to live in different tracts. D ranges from 0 to 100. A value of 60 (or above) is considered very high.
