Is 1% of America's Wealth Sitting on Our Coast? We Checked the Numbers

You hear it a lot around here: "There's about 1% of the whole country's money sitting on these islands." We pulled the official numbers to check. The short answer is that it depends on what you count, and the claim is closest to true for the four-county region, not for the islands by themselves.

First, apples and oranges

GDP measures what the country produces in a year. That's a flow, like a paycheck. Property value measures what land and buildings are worth right now. That's a stock, like a savings balance. Saying a coastline holds "1% of the economy" mixes the two. The fair test compares local property with all U.S. property.

What the tax rolls say (2025)

The Florida Department of Revenue publishes each county's "just value," the property appraiser's estimate of market value (FL DOR Data Book, just value report, PBC Property Appraiser FAQ). For real property (land and buildings) in 2025:

| County | 2025 real property just value | |---|---| | Palm Beach | $512.7 billion | | St. Lucie | $67.1 billion | | Martin | $57.5 billion | | Indian River | $49.0 billion | | Four counties | about $686 billion |

Source: FL DOR just value report. For scale, the whole state's real property was about $5.12 trillion, so these four counties are roughly 13% of Florida's total.

The islands themselves

The most famous barrier-island towns are big, but they aren't a trillion dollars:

• Town of Palm Beach: $34.7 billion in 2025 taxable value, second only to Boca Raton among the county's cities (PBC Property Appraiser, 2025 final roll). Taxable value is after exemptions, so market value is higher.
• Jupiter Island: about $4.4 billion in taxable value, per TCPalm's report on Martin County's roll (TCPalm). Its Census median household income is about $219,700, against a U.S. median of about $80,700. The margin of error is large, about ±$73,400 (Census Reporter, ACS 2020–2024).
• Hutchinson Island and the other beach towns: these aren't reported as one total in the sources we found, so we didn't guess.

Even counting Palm Beach and Jupiter Island together at roughly $39 billion taxable, that's under a tenth of one percent of U.S. household real estate.

The national yardsticks

• All U.S. household real estate: $47.9 trillion at the end of 2025. Adding nonprofits brings it to $52.0 trillion (Federal Reserve Z.1 via FRED, households, FRED series BOGZ1LM155035005A).
• U.S. GDP: $29.38 trillion in 2024 and $30.86 trillion in 2025, in current dollars (BEA via FRED).

The ratios

| Comparison | Result | |---|---| | Four counties ÷ U.S. household real estate ($47.9T) | about 1.4% | | Four counties ÷ households + nonprofits ($52.0T) | about 1.3% | | Four counties ÷ 2025 GDP ($30.9T), stock vs flow, not a like-for-like comparison | about 2.2% | | Palm Beach + Jupiter Island taxable (~$39B) ÷ U.S. household real estate | about 0.08% |

Our math, from the sources above. One caution: the county figures include business and commercial property, while the Fed's $47.9 trillion counts households only. That makes the 1.4% somewhat generous. The appraiser's just value and the Fed's market value are also built differently.

Verdict

• "1% of the country's property is in our region" (Palm Beach, Martin, St. Lucie and Indian River): roughly true, about 1.3–1.4%, with the caveats above.
• "1% is on the barrier islands": overstated by about tenfold or more, based on the town figures we could find.
• "1% of the economy": mixes a stock with a flow. Taken literally it comes out to about 2%, but that comparison doesn't mean much.

Fair version: our four-county stretch of coast holds a little over 1% of the value of America's household real estate. That's a lot for a region that size, and Palm Beach and Jupiter Island are among the most valuable places in it.
