Is there an independent [[read: not the Gilbert Press, Gilbert News, or Crain's Gilbert Business) source that proves there has been this deluge of yuppies living in Detroit? I see a lot of people reference this Midtown/downtown/corktown uptick, but the census data doesn't show any uptick in Detroit. Furthermore, do these people actually stay put, or are they bolting after a year or two? Anecdotal, but a few kids from my church tried the city and left after a frustrating 12 months. So, how many people are actually moving to these prime neighborhoods?
