The 30 Wealthiest Suburbs and Neighborhoods in America (2025)

America’s wealth remains geographically concentrated — but new hotspots are emerging.

While Silicon Valley and New York’s commuter towns still dominate, Florida and Texas are rapidly rising as centers of wealth thanks to favorable tax climates and luxury development.

Key Takeaways :

• Silicon Valley Dominance: Tech wealth continues to define modern American affluence. Atherton, Palo Alto, and Menlo Park together boast average household incomes exceeding half a million dollars — largely fueled by stock-based compensation and capital gains.
• The Rise of Southern Wealth: Florida and Texas suburbs like Palm Beach, Highland Park, and Indian Creek Village are drawing record inflows of high-net-worth individuals relocating from New York and California for lower taxes.
• Old-Money Enclaves Stay Strong: The Northeast’s historical centers of wealth — Scarsdale, Greenwich, and Short Hills — continue to rank among the highest in the nation, supported by finance, law, and executive income.
• Coastal Luxury Still Commands Premiums: From Malibu to the Hamptons, oceanfront real estate remains one of the most valuable asset classes in America. Even with recent market softening, many coastal enclaves exceed $3 million median home values.

Where do America’s wealthiest residents call home? From Silicon Valley’s tech billionaires to New York’s financial elite and Florida’s coastal millionaires, the geography of affluence is highly concentrated — and it’s shifting.

Using the latest IRS Adjusted Gross Income (AGI) data, Zillow’s 2025 Home Value Index (ZHVI), and local assessor figures, we identified the 30 richest suburbs and neighborhoods in the United States, ranked by median household income and median home value.

Below is the full list of 30 affluent communities, including their estimated 2025 household incomes, typical home values, and concentration of millionaire households.

The Geography of Millionaire Density

While income is one measure of wealth, millionaire household density offers a deeper look at true affluence. According to IRS and Wealth-X estimates:

• In Atherton, CA, nearly 4 in 10 households are millionaires.
• Fisher Island, FL, has fewer than 500 residents — but the highest millionaire share in the nation (~35%).
• Short Hills, NJ, and Scarsdale, NY, lead the East Coast suburbs with over 20% millionaire households.
• Indian Creek Village, FL, dubbed “The Billionaire Bunker,” is almost exclusively composed of ultra-high-net-worth households.

Methodology

This ranking combines:

• Median household income from the American Community Survey (2023) and IRS AGI ZIP data (2024–2025)
• Median home values from Zillow’s ZHVI (August 2025)
• Local assessor records and Wealth-X millionaire density reports

Top-coded Census values (>$250,000) were replaced with realistic income estimates derived from IRS and Bloomberg/SmartAsset ZIP-level analysis to reflect true affluence.
