I grew up in the Baltimore area, and while it's still pretty segregated, it used to be really segregated. There is a great book by a former Sun reporter, Antero Pietila, called "Not in My Neighborhood" which gives a history of the city through the lens of discriminatory housing practices. Baltimore historically had large African American, Jewish and southern and eastern European populations. Neighborhoods had restrictive covenants well into the 60s and maybe even the 70s. If you recall in the Wire, they had the east side and west side gangs - Prop Joe was east and Stringer was west. And that's because downtown bisects 2 large historically African American areas east and west of downtown. Further east closer to the old docks was very eastern European. The northwest part of town was heavily Jewish. My grandparents lived in north central neighborhood that had restrictive covenants - no Jews or African Americans there. As a kid in the early 80s, I worked at Baltimore Country Club, and there were no African Americans or Jews as members, and the only member whose name ended in a vowel was the president of Loyola College. And my favorite fast food restaurant back then was a place that mostly served polish sausage called Polock Johnny's. There used to be a fair amount of corruption too. Spiro Agnew was still getting kickbacks from his days as Baltimore County executive days when he was vice president. If you were a developer back then, you had to bribe the right county execs in order to put in a development.
