Every large metro area in the US (and probably around the world) has segregation issues.Perception vs reality. Move south if you want to see real segregation.
I get your point about large metros but take a trip around the south ...Mississippi, Alabama, Georgia, South Carolina and Florida (disclaimers: anything south of I-4 in Florida is not the south). Some areas it’s like taking a trip back in a time to the 60’s when it comes to segregation and attitudes. Even to some extent Atlanta.Every large metro area in the US (and probably around the world) has segregation issues.
It starts out as a convenience - people want to live around others like themselves (Milwaukee and Chicago are great examples of that with the various European nationalities grouping together). And that made it easier to also have black people segregated as well, given the attitudes at the time this started. And then the city and state governments used segregation to control people and keep them there, because you can't lose voters.
