Internal migration in the U.S.

Hurricane Katrina could potentially cause hundreds of people to relocate to new parts of the U.S., and it is just the latest catalyst in a history full of internal migration. What effects do these population movements have on our country? Historian James Gregory (Professor of History and Labor Studies, University of Washington, Seattle) and geographer Kavita Pandit (Professor of Geography, University of Georgia, Athens) join Chicago Public Radio's Gretchen Helfrich for the discussion. Gregory is the author of "The Southern Diaspora: How the Great Migrations of Black and White Southerners Transformed America." Pandit is coeditor of "Migration and Restructuring in the United States: A Geographic Perspective" and is vice president of the Association of American Geographers.
