Arizona doesn't appear on richest zip code list
If you're looking for some of the richest zip codes in America, you'll need to look outside of the desert.
According to Phoenix Business Journal, there were no Arizona zip codes on the list of America's richest.
Not surprisingly, the list was dominated by smaller, uber-upscale communities. Palm Beach, Fla., with a total of just 5,505 houses, landed the top spot.
California had five zip codes in the top 10. Pennsylvania, Connecticut, Illinois and Virginia also had zip codes in the top 10.
The survey looked at average household income and average household net worth. Only primary homes were considered, not secondary.
