A list of the top 15 richest suburbs in the US has been compiled, with some outlets noting that the wealthiest areas may not be what is expected. The rankings appear to include suburbs in various regions, including New York and the Bay Area, with some reports focusing on the income required to be considered "rich" in specific cities like Austin. The composition of the wealthiest suburbs may have changed over the past decade, but the exact details and rankings are not consistent across reports.
