US Population Decline Deepens Amidst Immigration Drop and Record-Low Births

America's population has experienced a significant decline, primarily driven by a sharp drop in immigration and a record-low birth rate. Immigration fell across every metro city area, contributing to the overall population decrease. Concurrently, the birth rate plummeted to 1.31 in 2025, marking the fewest babies born on record. These demographic shifts, alongside the impact of hurricanes that displaced residents from Gulf Coast areas, have resulted in slower population gains for numerous metro areas and counties nationwide.
