Infant Mortality


About Infant Mortality

Infant mortality is the death of an infant before his or her first birthday. The infant mortality rate is the number of infant deaths for every 1,000 live births. In addition to giving us key information about maternal and infant health, the infant mortality rate is an important marker of the overall health of a society. In 2021, the infant mortality rate in the United States was 5.4 deaths per 1,000 live births. (See Mortality in the United States, 2021).
