Where will you likely find yourself the poorest person in town? There are places where even a well-to-do household, by normal standards, would have a hard time keeping up with the Joneses. To identify the 50 richest areas in the U.S. for Businessweek.com, Little Rock data company Gadberry Group looked at all Zip Codes in the U.S. with more than 100 households and ranked them by the average income and net worth of their households. The area’s population change since 2000 was also taken into consideration, though only as a minor factor, and no areas with a decrease in number of households, where wealth might become less concentrated, were included. The results include many places around New York, Washington, D.C., and Silicon Valley. As Gadberry’s survey mainly captured data on primary residences, many affluent second-home markets, such as the Hamptons on Long Island and Aspen, Colo., did not make the top 50. Also, neighborhoods in such urban areas as Manhattan and San Francisco that have pockets of extreme wealth did not make the list because they have a greater diversity of income earners.

Note: As a reference, Gadberry Group identified the predominant demographic cluster in each area using categories from marketing technology company Acxiom. These clusters include “elite” couples and singles (people with enormous disposable income and no school-age children who indulge in luxuries), executives and professionals in their 40s and 50s without children (educated and well-compensated singles and couples who tend to be serious travelers and good investors), and wealthy families (suburban households with children who shop at upscale stores and enjoy leisure activities). For each neighborhood, the predominant group is noted in the caption.
