Apparently, East St. Louis is in such bad shape that even its Wikipedia page is fucked up.
In East St. Louis, the median household income is $21,324 and 35.1% of the population live below the poverty line.
While I techinically grew up in unincorporated St. Louis County, Creve Coeur is the municipality that bordered my subdivision and housed my high school. Only 20 miles from East St. Louis, Creve Coeur boasts a median household income of $75,032 and less than 3% of the population live beneath the poverty line.
It's interesting to me because I think most people I grew up with would consider themselves middle class. But statistically, the median household income places Creve Coeur close to the top 20% (lower limit for the top quintile in 2005 was $88,030).
Basically, everyone in America wants to believe that they are middle class.
