Key Takeaways

Florida (8.9%) and South Carolina (8.8%) follow next, with Southern states adding more residents than all other regions combined.
America’s population has grown by over 10 million people since 2020, with nearly three-quarters of this growth concentrated in the South.
With the rise of remote work, many migrated to Florida and Texas thanks to their sunnier climates and favorable taxes. Meanwhile, California has seen net out-migration, with people increasingly heading to more affordable states like Utah and Idaho.

Idaho witnessed the fastest population growth overall, at 10.4%.
Roughly a quarter of this growth is from California, drawn by the state’s lower cost of living, while roughly another 18% came from Washington. The vast majority, equal to about 80% of new residents, are under the age of 55.
Florida follows next in line, with 8.9% growth. Since April 2020, the state’s population has swelled by more than 1.9 million people, the largest absolute gain only after Texas. In total, five of the top 10 states by population growth were in the South.
In contrast, California and New York top the list for the largest population declines. Both states have lost more than 200,000 residents, with high living costs playing a major role.
As of December 2025, the median home price hit $818,000 in California and $501,000 in New York, well above the national median of $446,000. Combined with shifting work opportunities, these affordability challenges are helping fuel the outmigration.
