See, charts like these ain't a one-size-fits-all outchea.
I live about 20 miles west of Detroit. Median household income in my town is $84k. I make more than that and with this being only a 3 person household, that works out.
Detroit, however, has a median household income of $34,762, so if I was living in The City I'm more than paid... But that depends. My old neighborhood in Detroit (which is where I would want to live) Census Tract 5381, Wayne, MI, has a median income of $87,250 and the tract directly south of my old hood, Census Tract 5382, Wayne, MI, has a median household income of $137,987. I'd still be above the median income in my old hood, but a few blocks away from my old house I'd suddenly be good and below average. And with the housing costs the way they are over there in Sherwood Forest and Palmer Woods (which sits in that tract), I'd be struggling to keep up 'cause them cribs are $$$ so mortgages and taxes would be no joke.
