At nearly 132.7 million residents, the South is the most populous region. With a population gain of nearly 1.8 million — a change of 1.4% between 2023 and 2024 — the South added more people than all other regions combined, making it both the fastest-growing and largest-gaining region in the country.
The largest contributing component to this growth was international migration, which added 1.1 million people. Domestic migration netted another 411,004 residents. The South was the only region with positive net domestic migration, where the number of people entering the region exceeded those leaving. Natural increase also contributed 218,567 to the growing region.
Within the South, Texas (562,941) and Florida (467,347) had the largest numeric gains, and the District of Columbia grew the fastest (2.2%) from 2023 to 2024.
The population in the West grew by almost 688,000 (0.9%) to a total of 80,015,776 residents. This growth was consistent with the national trend and continued despite a net domestic migration loss of almost 170,000, offset by a gain of 667,794 from net international migration. There was a gain of 187,986 from natural increase. In the West, California (232,570) and Arizona (109,357) had the largest numeric gains between 2023 and 2024, while Utah (1.8%) and Nevada (1.7%) grew the fastest.
Just over 57.8 million people lived in the Northeast between 2023 and 2024. During that time, the number of residents increased by 0.76% — a gain of almost 435,000.
Growth in the Northeast largely stemmed from net international migration (567,420). The number of people moving from the Northeast to other parts of the country continued to slow as the region lost fewer residents via net domestic outmigration (192,109) in 2024 than in 2023 (278,245).
Within the Northeast, New York (129,881) had the largest numeric gains, and New Jersey (1.3%) had the fastest-growing population.
The population in the Midwest increased by over 410,000 (0.6%) to a total population of 69,596,584 in 2024.
The region had a net domestic migration loss of 49,214, far fewer than the net domestic outmigration of 89,787 in the previous year. The Midwest gained 406,737 people through net international migration and experienced a net gain of 52,741 from natural increase.
Within the region, Illinois (67,899) and Ohio (59,270) had the largest population gains, while North Dakota (1.0%) and Iowa (0.7%) were the fastest-growing states.
