Yeah I wondered about this too while watching the excellent BBC documentary Requiem for Detroit last night... it would seem to me from my family still living in the burbs of Detroit that a lot of those cities are doing fine, with some thriving. With so many people leaving Michigan, which burb is likely to grow/become the new detroit though?
I'm aware of that; however that won't result in the kind of population growth that parts of the suburbs are experiencing and those same areas haven't had mass exodus' either.
As Detroit transforms into something other than 'the largest city in Michigan' (which I guess it probably already has), I'm just wondering which if the little toes so to speak is in the strongest position to challenge for the new #1 spot.
