U.S. Population Growth Slows as Net Migration Dives

U.S. population grew 1.8 million (0.5%) from July 2024 to July 2025, the slowest pace since the pandemic, driven mainly by a historic drop in net international migration (2.7 million to 1.3 million); births and deaths were relatively stable. Growth slowed across regions and states, with the Midwest the only region where all states gained population and South Carolina the fastest-growing state, while Puerto Rico declined. Net international migration is projected to fall further, to about 321,000 by July 2026.
