A growing number of Americans migrated from predominantly blue states with steep taxes like California and New York to red states with lower taxes like Florida and Texas last year, according to a Bank of America analyst note that is based on findings from U.S. Census Bureau data and U-Haul rates.
Although the entire U.S. population as a whole grew by just 0.4% between July 2021 and July 2022, the data underscores major differences in population growth at the state level.
The South, which has states with some of the lowest individual income taxes in the country, was the fastest-growing region. Its population increased far faster than the national average, jumping by about 1.1% – or roughly 1.4 million people last year – a phenomenon described as the "Sun Belt migration." The region also benefited from about 870,000 Americans who left other parts of the country for warmer climates and lower taxes.
"This population shift paints a clear picture," said Janelle Fritts, a policy analyst at the Tax Foundation. "People left high-tax, high-cost states for lower-tax, lower-cost alternatives."
Among the bottom third, five states – California, Hawaii, New Jersey, New York, and Oregon – have double-digit income tax rates, according to the Tax Foundation.
About 343,000 Californians left the state last year, compared to about 300,000 New Yorkers. Illinois saw roughly 142,000 residents leave the state.
"The Census data and these industry studies cannot tell us exactly why each person moved, but there is no denying a very strong correlation between low-tax, low-cost states and population growth," Fritts said. "With many states responding to robust revenues and heightened state competition by cutting taxes, these trends may only get larger."
