The US infant mortality rate fell to an all-time low, though it still trails other similar nations

The U.S. infant mortality rate reached a record low in 2025, with 5.4 deaths per 1,000 live births, though it remains higher than in other high-income countries. The decline follows medical advances, public health efforts, and new measures like RSV vaccines for pregnant women and antibody shots for infants. However, disparities by race persist, and the U.S. rate lags behind nations such as Italy, Japan, and Sweden.
