Two Miamis: The Money Keeps Arriving. The People Keep Leaving.

Stand on Brickell Avenue and Miami looks like a city that can’t stop winning. Cranes swing over new towers. Citadel, the hedge fund giant that moved its headquarters here in 2022, is building a 58-story skyscraper on the bay. Sales of $1 million-plus condos jumped more than 15% in the first quarter of 2026. Hotels are raising rates faster than almost anywhere else in the country.

Now look at the moving trucks. Between July 2024 and July 2025, 72,254 more people left Miami-Dade for other parts of the United States than moved in, according to Census Bureau estimates. That’s the largest net domestic outflow on record for the county, up from about 67,000 the year before. And for the first time in years, immigration from abroad didn’t make up the difference. Miami-Dade’s population fell by 10,115, to about 2.8 million, the third-largest numeric drop of any county in the nation.

Both pictures are true. Together, they describe an economy splitting in two.

Who’s leaving

The numbers point to a simple driver: cost. In 2025, 54% of Miami-Dade households couldn’t afford basic necessities, up from 51% two years earlier, according to United Way data reported by Axios. Rents had already jumped about 49% in the first two years of the pandemic alone, the steepest increase among Florida’s large counties, according to Zillow figures analyzed by the University of Florida.

The exodus isn’t only from Miami. Broward lost 29,517 residents over the same period and Palm Beach County lost 11,953, while cheaper places like St. Johns County near Jacksonville and the Ocala area kept booming. South Floridians aren’t just shuffling between neighboring counties. Many are leaving the region entirely.

That has consequences for everyone who stays. “The collapse in domestic migration is a direct threat to jobs and paychecks for the state’s current residents,” Eric Finnigan, vice president of demographics research at John Burns Research & Consulting, told The Wall Street Journal. He warned it could also drag on home values, the main source of wealth for most Florida families.

Who’s arriving

At the top, Miami is still a magnet. Wealthy people keep coming, including some looking to avoid a possible wealth tax in California, according to Business Insider. Buyers closed 424 condo deals of $1 million or more in the first quarter, up from 368 a year earlier, at a median price of about $1.84 million, according to CondoBlackBook.
