Fascinating article on population shifts in Cleveland. Basically, it goes like this: Rust Belt cities have witnessed the hollowing out of the urban cores for decades now. This means that residential real estate in the city is dirt cheap. You know who loves cheap urban real estate? Young White people, who are flocking to the city as they can purchase houses at rock bottom prices that are very close to finally reflowering city neighborhoods.
Meanwhile, the collapse of the housing market in the suburbs has had its own effect on Black city residents -- they see this is their big shot to cash in on the American dream (nice house with a yard away from the city). So as we're seeing an influx of White couples into the city, we're seeing a transition of Black families out to the suburbs. The upshot? Far more integrated neighborhoods.
