313WX is completely correct. Why is that hard to believe, considering people move to cities in different states without ever updating their driver's license, let alone moving within the same state?
I know the originator of this thread is requesting hard data, but what he wants may simply not exist. I suggest he simply go spend a couple of days in these areas in question to see himself, even try to rent an apartment in the area.
Again with the bar set at census numbers, and renters never move without changing their address, even this may not suffice.
