Having been a Detroiter during the white flight years it was an interesting pattern that the East/West division of the city was largely maintained as people moved to the suburbs. East Siders went to Warren/Macomb Co., West Siders to West Wayne and Oakland Co. The East Side of Det had more transplanted Southerners prior to the exodus than the west side, and the racial animus carried through, even if muted, to the suburbs. So you still find today that Oakland county is bluer and Macomb Co redder.
