Some of these zip codes are very small, with only a few dozen filers. As Jed Kolko, the former chief economist at Trulia, points out, many are actually non-resident locations like company headquarters or government buildings.
Here are the same results for the North East - Middle Atlantic and the North East - New England. It probably won't surprise you that New York City has the wealthiest zip code in the Middle Atlantic (10104), with an average income of $2,976,929. In New England, Greenwich, Conn. (06831) ranks first, with $414,686.
The top five zip codes in America with the highest average income probably won’t surprise you: three of the five are in New York City, while one is in Miami Beach.
