The U.S. population saw its slowest rate of increase since the COVID-19 pandemic, with President Donald Trump’s sealing of the border being credited with the development, the U.S. Census Bureau reported.

The U.S. population grew by 1%, 3.2 million, between July 2023 and July 2024 but decreased to a 0.5% growth rate from July 2024 to July 2025, adding just 1.8 million new people. The primary culprit was a plummet in international migration, declining 53.8% from 2023-2024 to 2024-2025.
