Only a few areas in Alabama have become more white in the past 20 years.

...and that's apparently the case nationally as America becomes a more diverse nation.

     From a (paywall) N.Y. Times story:

"As the country has become more racially and ethnically diverse over the past 40 years, American neighborhoods have, too. And the change is most apparent in places that were once all white"

     But the interactive map that accompanies the Times story shows only one Montgomery-area place where there has been significant change--from black to white---and that is Tuskegee. 

     There are many places where the population became more non-white. And most of the area did not change racially.
