In the 1970's crime spike in many American cities, and the 'burbs' became a real aspiration. The middle class simply moved out. American cities have mostly 'business cores' anyhow, with big banking buildings, not like in Europe where they're pedestrian and have homes. In some cities, there's been a renaissance of urban living and people moving back in since the 2000's, but it depends on the city. My guess is that 80% of what's going on here is just that: demographic migration. What we need is greater Chicago data and probably statewide as well. I suspect you'll find the 'exaburbs' doing really well.
