This is determined by looking at the median household income in each county. Just for reference, the average median household income in the US is $46,326 according to the last Census, while all these counties fall from almost $100,000 and beyond. And if you do happen to hail from one of these spots, congratulations! Try bringing it up at a party and see what happens.
