The Location of Ethnic and Racial Groups in the United States.

The distinctive regional and urban locational patterns of thirty-three ethnic groups in the United States are analyzed from two different perspectives. First, who are the numerically important groups in each region? Second, from the perspective of the groups themselves, where are they spatially concentrated? We hypothesize that the forces generating distinctive ethnic locational patterns are strongest at the time of the initial settlement; thus the longer a group has been present in the United States, the less geographically concentrated it will be. This is found to be true for most ethnic groups except blacks and American Indians, whose specific social and political situations explain their particular concentrations. However, the early settlement patterns still affect the ethnic makeup of various areas of the nation, even though the concentrations have diminished over time. Moreover, although the 1975-1980 patterns of internal migration (analyzed through a Markov Chain model) are tending to reduce some of the distinctive geographic concentrations in the nation, this will still not fully eliminate distinctive ethnic concentrations. Groups differ in their propensities to leave or enter each area in a way that reflects the existing ethnic compositions of the areas. Thus even with the massive level of internal migration in the nation, there is no evidence that the substantial ethnic linkage to region is disappearing. [ABSTRACT FROM AUTHOR]
