New Orleans, for example, is supporting an increasingly concentrated population of unskilled poor as industry and jobs move to the urban fringe. Between 1970 and 1975 New Orleans lost 3.2 percent of its central city population while the suburban portions of the metropolitan area grew by 26.9 percent. More recent data for the 1970-1980 period show a continuing outmigration from the central city of 6.2 percent. Other major southern cities that report this pattern of central city population decline over the 1970-80 are Birmingham (-6.3%), Atlanta (-14.0%), Louisville (-17.5%), and Norfolk (-17.1%).
