Port St. Lucie is officially the top destination for residents fleeing South Florida’s affordability crisis, according to new migration data – and the numbers tell a striking story about where the Treasure Coast is headed.
Port St. Lucie Zip Codes Dominate Migration Rankings
A 2024 Q4 report from Miami Realtors, using CENSAI migration data tracking 270 million adult consumers, ranked Port St. Lucie’s zip code 34987 as the single most popular destination among all Southeast Florida zip codes for domestic movers.
Two additional PSL zip codes – 34953 and 34952 – also made the top 10, giving St. Lucie County three of the region’s hottest migration destinations.
Miami-Dade’s Affordability Crisis Fuels the Exodus
The timing is no coincidence. Miami-Dade County lost a net 10,115 residents between 2024 and 2025 – the third-largest population decline of any county in the United States, according to the U.S. Census Bureau.
The primary drivers: an average home price of $711,025, studio apartments consuming over 53% of a median earner’s income, and homeowner insurance premiums averaging $15,460 per year.
For many of those leaving, Port St. Lucie has become the answer.
