Top Gaining States
North Carolina, South Carolina, Tennessee, and Arizona also ranked among the top destinations for interstate movers, underscoring the broader population boom across the South and Sun Belt. Adjusted for population size, South Carolina posted the nation’s largest gain from domestic migration at 1.12%, fueled by more than 29,000 incoming households carrying roughly $4.1 billion in taxable income.
Drivers of Migration
Experts say the migration boom reflects broader affordability pressures pushing households toward lower-cost, lower-tax states across the South. Megan Mauro of the Texas Business Association tells Fox News Digital that low taxes and light regulation are key drivers of business migration to the Lone Star State.

The data highlights the growing economic influence of Southern and Sun Belt states, while coastal blue-state strongholds experience significant outbound losses.
