White flight is definitely happening in Philadelphia MS, just a little slower.
It is only recently becoming majority black.
The effects of white flight are likely just beginning.
From the 2000 to the 2010 census
2000 White 55% Black 40%
2010 White 47% Black 47%

You can even see white flight in Tchula with it’s small percentage of whites.
Down 59% between 2000 and 2010.
2000 White 55% Black 40%
2010 White 47% Black 47%
That could be from blacks having more kids than whites.
