What parts of the United States are growing in population? Look to the South:

The Vintage 2023 population estimates show broader trends reflecting pre-pandemic norms, with fewer deaths and an increase in migration spurring growth. The net result was a gain of more than 1.6 million people in the past year, a 0.5% increase that brought the total U.S. population to 334,914,895…
Overall, 42 states saw population increases this year, topped by Texas, Florida, North Carolina, Georgia, South Carolina, Tennessee and Arizona.
The South accounted for 87% of the nation’s population growth, adding more than 1.4 million residents. The Midwest reversed a two-year slide, adding more than 126,000 people for a modest 0.2% increase. The West region also saw a 0.2% increase, while the Northeast declined by 0.1%, according to census data.
The South is the only region that sustained its population growth throughout the pandemic, fueled by both domestic and international migration.
The ongoing population shift to the Sunbelt continues. It may not last forever but this is a consequential in-process change that affects numerous aspects of American life.
