Cities with significant black populations in their region

All this talk about cities with large black populations has got me thinking about the places that have such and the ones that doesn't.  Statistically, a place with a large black population is based upon the percentage being 15% or greater of its overall population being considered African American or black.  Everyone (and their mother) is familiar with some of places off the top of their head like New York, Chicago, Detroit, Philadelphia, Washington DC, and nowadays Atlanta.  However, there are some other cities with some impressive black populations, but overshadowed by the aforementioned places.  Here is a list of these places:

Houston
Charlotte
Memphis (which has the highest concentration of any metropolitan area with 1 million+ inhabitants at 43.5%)
Baltimore
St. Louis
Kansas City
Birmingham
Raleigh/Durham/Chapel Hill
Greensboro/Winston-Salem/High Point
Norfolk/Virginia Beach
Richmond
Dallas/Fort Worth
Cleveland
Miami/Fort Lauderdale/West Palm Beach
New Orleans

Here are some ideal places where one can find black culture in the region, but doesn't want to reside in those in the initial list of places like NYC to DC to the ATL.
