Hmmm...interesting Dale.  But many of what you have listed there describes them (they are a young couple, I'd estimate early to mid-30's), there are a few stickers on the car (a minivan..forget which type, yes around 10 years old), they have another older Volkswagen something or other, both smoke, and look a tad "down home" I wouldn't say unkempt though.  Keep to themselves for the most part.  The wife works for sure, her car makes a hell of a noise each morning.  I don't know if he does. 

Where did you find those stats?  Somewhat uncanny, really.
