There's a very interesting article here about "white flight." Unlike the more common stories about this, this story isn't about whites moving out of an area when a black community arrives, to some newly-gentrified area which is guaranteed to have better schools and so on than the place they're abandoning: it's about whites moving out of an area when it becomes too predominantly Asian, to a nearby community with worse schools, and often taking a direct economic hit to do so.
The way in which this reverses our usual expectations highlights a key research result which the article discusses: race, not economics, is alone a predictor of the "white flight" phenomenon.
