Via Planet Money, the Discovering Urbanism blog does an interesting chart comparing the income in the urban core to the income in the metro area as a whole for several American cities:

The trends here are very pronounced in some metro areas but the blue line showing the 40 city average looks pretty muted.

And Detroit continues its relative decline vis-a-vis the rest of the metro area even as the entire Michigan boat is trending downwards.
