Americans are fleeing these florida communities

In recent years, Florida has been one of the fastest growing states in the country. Between April 2020 and July 2025, Florida’s population expanded by over 1.9 million people – the most of any state with the exception of Texas, according to the U.S. Census Bureau. But unlike Texas, a state where births outnumbered deaths by over 700,000 since mid-2020, Florida’s population boom was driven almost entirely by an influx of new residents moving in from across the country and around the world. 

With a warm climate and no state income tax, Florida has demonstrably established itself as one of the most popular places to live in the United States. Not counting births or deaths, Florida’s population grew by over 2 million people between 2020 and 2025, the largest net-migration increase of any state in the last half decade. Over the same period, the number of Americans moving to Florida from other parts of the country outnumbered those leaving for other parts of the country by approximately 890,350 – the largest increase due to domestic migration alone of any state. 

But the latest Census Bureau migration flow data shows that The Sunshine State may be losing its luster. Between July 2024 and July 2025, domestic migration led to a net-increase of only 22,500 people in Florida, trailing over half a dozen other states, and well below Florida’s 5-year average net-influx of over 178,000 Americans. In many Florida counties, both inland and coastal, Americans are now leaving far faster than they are moving in. 

Using data from the U.S. Census Bureau’s Population Totals and Components of Change program, Climate Crisis 247 identified the Florida communities that Americans are fleeing. We ranked all 67 counties in Florida on domestic net-migration between July 2024 and July 2025 – or the number of Americans who moved in from other parts of the country, less those who moved out to other parts of the country. Supplemental data on median home list prices and projected flood risk and sea level rise are from Realtor.com and Climate Central’s Coastal Risk Finder tool. Only the 10 counties in Florida with the largest population decline due to domestic net-migration are ranked. 

The counties on this list lost anywhere from 1,016 to 29,517 people to domestic migration alone between mid-2024 and mid-2025. Outbound migration may be fueling sharp housing market declines, as median list prices fell by as much as $51,000 in these places over the same period. Reasons for the exodus vary, but many who have left the state cite the surge in insurance costs as rising natural disaster risk looms over much of the state. In the coastal areas on this list, sea levels are projected to rise more than 2 feet by the end of the century, and severe flooding is expected to become far more common within the next three decades.
