I don't get why most of these rougher areas are near African American majority towns. Down in the Baltimore-Washington DC area, most of the suburbs especially near the Capital Beltway and Six Flags America are African American majority but after visiting the area five times in 2 years, I found out that 80% of the suburbs there are nice, wealthy towns due to the government facilities there (Silver Spring, Bowie, Glen Burnie, New Carrollton, Landover, etc.).
