The Geography of Extreme Wealth
Median household income in the US is approximately $75,000. But in the wealthiest ZIP codes, median income can be 5–10 times that number — concentrations of wealth that reflect the geography of finance, technology, and inherited money in America.
The following ZIP codes consistently rank as the highest-income in the country, based on IRS Statistics of Income and Census Bureau American Community Survey data.
Top Highest-Income ZIP Codes
| ZIP Code | Location | Median HH Income | Primary Driver |
|---|---|---|---|
| 94027 | Atherton, CA | $250,000+ | Silicon Valley tech executives |
| 07620 | Alpine, NJ | $220,000+ | NYC finance, entertainment |
| 10007 | Lower Manhattan, NY | $200,000+ | Finance, professional services |
| 90210 | Beverly Hills, CA | $175,000+ | Entertainment, real estate, finance |
| 06883 | Weston, CT | $195,000+ | NYC commuter hedge fund managers |
| 02493 | Weston, MA | $185,000+ | Boston finance and biotech executives |
| 60022 | Glencoe, IL | $180,000+ | Chicago business and finance |
| 10004 | Wall Street, NY | $175,000+ | Financial industry |
Note: These are median figures — half the households earn more. Atherton, CA, has been called "the wealthiest town in America" by several analyses and is home to numerous Silicon Valley billionaires.
What Drives Wealth Concentration in ZIP Codes
High-income ZIP codes aren't random. They form clusters around several specific drivers:
Finance Industry Proximity
The wealthiest ZIP codes in New York, Connecticut, and New Jersey are dominated by Wall Street and hedge fund professionals who cluster in specific wealthy suburbs (Darien, CT; Greenwich, CT; Alpine, NJ) or Manhattan neighborhoods (Tribeca, Upper East Side, West Village).
Technology Industry Wealth
Silicon Valley's wealth is extraordinarily concentrated. The cities immediately around Stanford — Atherton, Portola Valley, Los Altos Hills, Hillsborough — have among the highest per-capita wealth in the world. Stock grants from IPOs have minted thousands of multimillionaires in these ZIP codes.
Inherited Wealth Clusters
Some of the wealthiest ZIP codes in America are in communities that have been wealthy for generations: Grosse Pointe, MI (auto industry fortunes), Palm Beach, FL, and certain ZIP codes in Boca Raton and Scottsdale.
How This Data Is Used
High-income ZIP code data has several practical applications:
- Real estate: Investors and developers track wealth concentration to anticipate demand
- Retail and restaurant targeting: Luxury brands specifically target high-income ZIPs for marketing
- Policy research: Economists use ZIP income data to study inequality trends
- School funding research: Education advocates track income-school quality correlations by ZIP
The Other Side of the Ledger
America's poorest ZIP codes are equally clustered — primarily in rural Appalachia, the Mississippi Delta, parts of the Deep South, Native American reservations, and in pockets within major metros. The gap between the highest and lowest income ZIP codes within a single metro area is often staggering: within 10 miles in almost any major city, you can find ZIPs with median incomes 5–8x apart.
