Turns out I was quite wrong, This is the most segregated city But just as I suspected, Chicago isn't even in the top five. It took me all of 30 key strokes to find this out. Can we put this nonsense to bed now? It's not nonsense. It's a well-established historical and sociological idea. Like I said, look at how many links have Chicago at the top. I never said all studies would have Chicago at the top. If the city has fallen from the top in recent years (even though I know many studies and experts still feel it's up there), hey great...that doesn't erase the better part of a century where it was the most visibly segregated major city in America. The social rammifications of such a situation doesnt just vanish. You're ignoring all the other links for the sake of one (from 2002) that backs up your point. Take this for what it's worth, but I took some education classes at Marquette, where they emphasize urban education. I believe I remember hearing that, depending on the year, that Milwaukee, St. Louis, and Detroit are the most segregated. Again, that's just going off of memory, but the professor taught in both St. Louis and Milwaukee. As for Chicago, there is no doubt in my mind that we are 'up there,' if only historically. But I'd make the argument that the larger the city, the more likely it is to make the segregation list. Again, just a theory, but it seems like a product of the system.
