Infant mortality rate is a measure of how many babies under one year old die each year compared to how many are born. It’s usually expressed as some number out of 1000; i.e, about 7/1,000 infants die before reaching a year old in the United States (which ranks us about 29th in the world). Areas with high poverty and poor healthcare tend to have high infant mortality rates.
