THE DIMENSIONS OF SEGREGATION REVISITED

In this article the authors replicate and extend the methodological an alysis of Massey and Denton (1988), which conceptualized residential s egregation as a multidimensional construct with five axes of spatial v ariation: evenness, exposure, concentration, centralization, and clust ering. To reproduce their work, the authors of this article factor ana lyzed 20 indexes of segregation computed in 1990 for three groups in 5 8 metropolitan areas. They extended Massey and Denton's analysis by ex panding the set of metropolitan areas to include all 318 defined for 1 990, and they broadened it by carrying out systematic comparisons acro ss ethnic groups. This study's analyses reconfirm the multidimensional nature of residential segregation; however the authors also find that the indexes recommended by Massey and Denton to measure concentration and clustering do not function quire as well in 1990 as in 1980. Alte rnative indexes are considered as possibilities, but in the end, using the same indexes is recommended to maintain continuity.
