A major demographic shift is changing the political and economic landscape of the United States. Millions of Americans are leaving high-tax, high-cost states like New York and California for more affordable places in the Sun Belt.
This is a worrying trend for the Democrats, who used to have a supermajority in the coastal states.
The U.S. Census Bureau’s 2024–2025 migration data shows that New York and California are among the top ten states losing the most residents, while states like South Carolina, Tennessee, and Florida are gaining the most. Lower income taxes, right-to-work laws, and affordable housing are big reasons for this trend.
Taxes: A Big Factor
The difference in taxes is clear: the top 10 gaining states have an average top income tax rate of 3.92 percent, while the top 10 losing states average 8.80 percent. People in the losing states also pay 60 percent more in state and local taxes per person.
This movement is not just about money; it’s also political. The Democratic Party, which has long depended on support from cities and immigrant communities, is feeling the impact as its base moves away.
Still, immigrants play a key role in the economy. Just in New York City, undocumented immigrants added $40 billion to the state’s economy in 2021 and paid billions in state and local taxes, according to the Fiscal Policy Institute.
As the Cato Institute revealed in its recent survey, across the country, immigrants created a fiscal surplus of $14.5 trillion from 1994 to 2023, paying more in taxes than they received in public services. But as more immigrants settle in Republican-led states like Texas and Florida, the balance of political power is shifting. Stateline reports that the arrival of border migrants in GOP states could change congressional representation, reducing Democratic influence in traditional strongholds even though those areas still have large immigrant populations (Stateline).
Texas Supplied the Most New Residents of any U.S. State
Surprisingly, Texas is the leading U.S. state in supplying migrants to other states, with residents moving other states like California, Oklahoma, and Louisiana. However, the Southern state itself gained over 2 million people between 2020 and 2024.
The Independent noted the trend is largely due to its huge population (31 million), which naturally generates high volumes of outbound migration. California, the most populous state (39 million), was the top source of migrants to western states and Tennessee, while Florida (23 million) dominated flows into Alabama, Georgia, and North Carolina, though rising costs are making it less attractive to retirees. All in all, the Sunshine State has gained 1.8 million residents this decade, the second most of any state.
Overall, the largest states—Texas, California, Florida, and New York—produce the most domestic migrants simply because of their size.
Meanwhile, international migration remains the primary source of new residents in most states, except in smaller states like Oklahoma and Wyoming, where domestic migrants from larger states are dominant.
This mix of economic migration and demographic change is a big challenge. While Democrats still benefit from immigrant contributions, their political power is spreading out across a country that is leaning more conservative.
