Segregation is common in US cities, and not just in the South. A friend in civic tech likes to say, "there is only one map of Chicago". Over time I've found it to be true: whether you're looking at these types of amenities, census data, crimes, health metrics. If you look at mapping apps like Runkeeper, you'll be able to point out U.Chicago as an island of activity within the South Side. Over time, ideas of how our cities are and ought-to-be get cemented in and polarized. Housing prices reflect that pretty well and businesses listen to that before opening a new location. When economies do grow, instead of gradual betterment of everyone living there, you see a neighborhood flip/gentrify so quickly; look at Bushwick or Williamsburg in Brooklyn.
