The Duncan Segregation Index is a measure of occupational segregation based on gender that measures whether there is a larger than expected presence of one gender over another in a given occupation or labor force by identifying the percentage of employed women (or men) who would have to change occupations for the occupational distribution of men and women to be equal.
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.
Isolation index measures the degree to which people inhabit geographic units inhabited primarily by members of their own group. It is usually denoted by I. It is usually denoted by I. It varies from 0 to 1.0 and is defined as the proportion of own-group members in the unit of the average person.
The LH index is also related to the dissimilarity index of segregation. All three indexes are special cases of the more general Δ {\displaystyle \Delta } index of dissimilarity. [ 5 ] The LH index is related to the amount of wasted vote , which only measures the difference between votes cast and seats obtained for parties which did not obtain ...
Morisita's overlap index, named after Masaaki Morisita, is a statistical measure of dispersion of individuals in a population. It is used to compare overlap among samples (Morisita 1959). This formula is based on the assumption that increasing the size of the samples will increase the diversity because it will include different habitats (i.e ...

A recent study of housing discrimination using matched pairs of home seekers who differed only in race to inquire about housing show that for those seeking rental units, blacks received unfavorable treatment 21.6 percent of the time, Hispanics 25.7 percent of the time, and Asians 21.5 percent of the time. Moreover, blacks interested in ...
In this scenario, the similarity between the two baskets as measured by the Jaccard index would be 1/3, but the similarity becomes 0.998 using the SMC. In other contexts, where 0 and 1 carry equivalent information (symmetry), the SMC is a better measure of similarity.
