The research proposed for this administrative supplemental project will extend the parent project?s work toward evaluating migration processes associated with race-ethnic redistribution — both across and within large US metropolitan areas.

This supplementary project will extend the time frame of the parent project
beyond the year 2000, by employing recently available migration data from the 2005-7 American Community Survey. The new analyses will continue to address the parent project?s main aims: (1) to evaluate inter-metropolitan migration processes of key race-ethnic groups to determine if they are leading to reduced concentrations across metropolitan areas;(2) to evaluate intra-metropolitan (city suburban) migration processes to determine if they are leading to reduced concentration within metropolitan areas; and (3) to estimate the overall impact of these migration processes on metropolitan race-ethnic populations.

These aims will be evaluated based on propositions drawn from the theory of spatial assimilation. They will focus on the migration of Hispanic and Asian nationality groups who have been known to disperse beyond traditional concentration areas since 2000, but for whom the migration processes affecting this dispersal are not well understood.

In addition to extending the time series of the parent project, this supplementary analysis will permit an evaluation of the capabilities of migration data available with the American Community Survey (ACS). Since the 2010 Census will not include a migration question, these analyses will provide a benchmark for future migration analyses with the ACS.

This project will involve a new research team from the University of Maryland with particular expertise for this work, but will also build on the resources and expertise of the parent project?s research team.
