New York is feeding out-of-state migration into Southeast Florida
New York County and Los Angeles County lead the top 10 counties of origin of out-of-state adults 18 years old and over who moved to Southeast Florida in 2025 Q2, based on Censai by Rushmore Labs data analyzed by the Miami Association of Realtors. CENSAI Population Intelligence by Rushmore Labs has a database of 270 million adult consumers with address histories going back to 2018. The data is coalesced with third-party proprietary consumer data to track domestic migration of adults 18 years and over.
Of the top 10 counties, five New York counties were in the top 10: New York County, Nassau County, Suffolk County, Kings County and Queens County.
In Miami-Dade County, New York County was the top origin of out-of-state movers, followed by Los Angeles County, and Kings County.
In Broward County, Los Angeles County and Suffolk County, New York tied for first place, followed by Nassau County.
In Palm Beach County, three New York counties were the top origins of out-of-state movers: Nassau County, Suffolk County, and New York County.
In Martin County, Santa Clara County in California was the top origin of out-of-state movers, followed by Mecklenburg County, North Carolina, and Suffolk County, New York.
In St. Lucie County, three New York counties were the top origins of out-of-state movers: Suffolk, Nassau, and Queens.
Miami Association of Realtors (MIAMI) analysis of the US Census Bureau American Community Survey 2023 PUMS data shows that New York is a top origin of people moving to Southeast Florida. In 2023, 72,424 people moved from New York to Florida, outpacing the count of New Yorkers moving to New Jersey (56,098) and to California ($34,595).
Miami Association of Realtors (MIAMI) analysis of the Internal Revenue Service 2022 migration data also showed that $9.5 billion of household income (adjusted gross income) flowed out of New York to Southeast Florida in 2021 based on 2022 tax returns (latest available data).
Widening tax differential is likely to bolster migration from New York
Migration from New York could potentially increase in 2026 as the tax differential between New York and Florida widens under Mayor-elect Mamdani.
Currently, New York City’s general business corporation tax is at 4.875% to 7.25%, which Mamdani has pledged to raise to 11.5% to match New Jersey’s. In Florida, the corporate tax rate is 5.5%.
The New York state income tax rate ranges from 4.75% to 10.9% In addition, there is a flat 3.9% New York City income tax. Mamdani’s agenda calls for a 2 percent New York City Income Tax for anyone making more than $1 million a year could impact 34,000 households. There is no state income tax in Florida and no income tax at the city level.
A poll conducted for the Daily Mail by J.L. Partners found that 9 percent of New Yorkers would “definitely” leave the city (765,000 of the city’s $8.5 million population) and another 25 percent would also “consider” leaving.
Real estate agents in Palm Beach County, the top state for New York movers, reported an increase in New York clients looking to buy property in the cities of Jupiter, Palm Beach Gardens, Delray Beach, and Boca Raton.
