From coastal Silicon Valley enclaves to leafy New York commuter hubs and high-end Texas university towns, America’s richest suburbs are concentrated primarily in California, New York, and Texas. Based on an analysis of mean household income from MoneyLion using U.S. Census data (evaluating suburbs with at least 5,000 households), these communities share key traits: top-tier school districts, tight housing inventory, and manageable commute distances to major metropolitan centers.

Methodology & Exclusions
- Mean vs. Median Impact: Mean income measures can be pulled upward by ultra-high-net-worth residents. When measured strictly by median household income, Sammamish, Washington (a Seattle suburb) takes the top spot in the U.S. at $238,750.
- Size Requirements: Ultra-wealthy enclaves with under 5,000 households—such as Kenilworth, Illinois, or Chevy Chase, Maryland—were excluded due to the size threshold.
