What is the segregation formula?

Answer 1

The segregation formula, often referred to in the context of urban studies or Social Sciences, measures the degree to which different groups (such as racial or ethnic groups) are separated within a given area. One common formula used is the Index of Dissimilarity (D), which quantifies segregation by comparing the distribution of two groups across different geographic areas. It ranges from 0 (complete integration) to 1 (complete segregation). The formula is calculated as D = 0.5 * Σ |(P1i / P1) - (P2i / P2)|, where P1i and P2i are the populations of groups 1 and 2 in area i, and P1 and P2 are the total populations of groups 1 and 2, respectively.
