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

  • L'indice de dissimilarité est un indice de mesure de la ségrégation proposé en 1955 par Otis Dudley Duncan et Beverly Duncan dans l'article « A Methodological Analysis of Segregation Index », paru dans la revue American Sociological Review. Il mesure la séparation spatiale de deux groupes différents et compare leur distribution à travers diverses unités spatiales. Autrement dit, si l'on considère une population A et une population B réparties dans différentes unités spatiales, il exprime la part de la population A ou B qui devrait se déplacer pour que les deux populations soient uniformément réparties dans chaque unité spatiale. Cet indice est notamment utilisé pour établir une mesure spatiale des ségrégations résidentielles et scolaires. (fr)

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. (en)

Cet indice est notamment utilisé pour établir une mesure spatiale des ségrégations résidentielles et scolaires. Mis en relation avec la courbe de Lorenz, l’indice de dissimilarité est égal à la distance verticale maximale séparant la diagonale d’équirépartition et la courbe de ségrégation (fr)
