What are the dimensions of segregation?
They argued that segregation is not a unidimensional construct, but encompasses five distinct dimensions of spatial variation. The five dimensions they identified are: evenness, exposure, clustering, concentration, and centralization.
What does the isolation index measure?
The isolation index measures “the extent to which minority members are exposed only to one another,” (Massey and Denton, p. 288) and is computed as the minority-weighted average of the minority proportion in each area.
What does the index of dissimilarity measure?
The Index of Dissimilarity is the most common measure of segregation. Although it has limitations, it is relatively easy to calculate and to interpret. Value of D represents the proportion of a group that would need to move in order to create a uniform distribution of population.
What is the correct definition of segregation?
segregation, separation of groups of people with differing characteristics, often taken to connote a condition of inequality. Racial segregation is one of many types of segregation, which can range from deliberate and systematic persecution through more subtle types of discrimination to self-imposed separation.
What is the difference between segregation and isolation?
As nouns the difference between segregation and isolation is that segregation is the setting apart or separation of things or people, as a natural process, a manner of organizing people that may be voluntary or enforced by law while isolation is (chiefly|uncountable) the state of being isolated, detached, or separated.
What is a segregation score?
The residential segregation index ranges from 0 (complete integration) to 100 (complete segregation). The index score can be interpreted as the percentage of either Black or white residents that would have to move to different geographic areas in order to produce a distribution that matches that of the larger area.
What is racial dissimilarity?
The Racial Dissimilarity Index measures the percentage of the non-hispanic white population in a county which would have to change Census tracts to equalize the racial distribution between white and non-white population groups across all tracts in the county.
What is black Hypersegregation?
Hypersegregated areas are those where black residents experience high levels of segregation across a range of measures, including the extent to which black residents live in neighborhoods that are all or almost-all black and the extent to which black residents live in cities’ cores, where housing is often oldest.
What is Massey and Denton’s index of segregation?
Massey and Denton (1988) used an extensive literature search and cluster analysis to identify 20 different indexes of segregation and classify them into five key dimensions of segregation.
What are the isolation and interaction indexes for segregation?
When there are only two groups, the isolation and interaction indexes sum to 1.0, so lower values of interaction and higher values of isolation each indicate higher segregation.
What are evenness measures of segregation?
Evenness measures of segregation compare the spatial distributions of different groups among units in a metropolitan area. Segregation is smallest when majority and minority populations are evenly distributed. The most widely used measure of evenness is the dissimilarity index.
