William Ferris of the Center for the Study of the American South says before the change, the South had always been viewed as black and white. Now, the nation's two largest minority groups are sorting out whether their relations will be driven by competition and mistrust or a common bond. The tension is more apparent in the South. While blacks are still more numerous in the Southeast, except for Florida, a rush of immigrants from Spanish-speaking countries is changing racial interaction across the region. Several Southern states now lead the nation in the growth of Hispanic residents and illegal immigrants.
