To assess the relative roles of race and ethnicity in shaping patterns of residential segregation, this article utilizes indices of segregation and a geographic mapping strategy to examine the residential patterns of West Indian blacks in the greater New York City area. The socioeconomic characteristics of neighborhoods occupied by West Indian blacks are also examined and compared to those of areas occupied by African Americans. The results indicate that, on one hand, West Indians are largely denied access to residential areas occupied predominantly by whites and are confined to areas of large black concentrations. On the other hand, West Indians appear to have carved out somewhat separate residential enclaves within these largely black areas, and there is evidence to indicate that these areas are of somewhat higher quality than areas occupied by similar concentrations of African Americans. The discussion of these results focuses on the reciprocal relationship between the formation of these distinct residential enclaves and the maintenance of a distinct West Indian ethnic identity.
