The richest zip code in America is just as exclusive and elite as the people who live there, according to an analysis by Bloomberg News.
To no one’s surprise, neighborhoods in California and the New York tri-state area comprise a majority of the top 20 richest U.S. zip codes. States with favorable tax structures like Florida and Wyoming are drawing the wealthy, too.
Bloomberg evaluated IRS data for zip codes with more than 200 tax returns as of the 2015 filing season, and with 500 residential households according to the latest Census tally. More than 22,000 zip codes met the criteria.
Who didn’t make the top 20? Any of the zip codes in Manhattan. However, several Manhattan neighborhoods made the top 50, starting with the venerable zip code of 10005 at No. 21 on the list. This one is home to the New York Stock Exchange and sits at the edge of the iconic "Charging Bull" sculpture.
