Infant Mortality

Infant mortality is defined as the death of an infant before his or her first birthday. Infant mortality is related to the underlying health of the mother, public health practices, socioeconomic conditions, and the availability and use of appropriate health care for infants and pregnant women.8, 116 Despite medical advances and public health efforts, the mortality rates of Black, non-Hispanic and American Indian or Alaska Native, non-Hispanic infants have been consistently higher than the rates of other racial and ethnic groups.20, 117 Higher rates of infants born preterm or at low birthweight account for most of the deaths among Black, non-Hispanic infants.20 Higher rates of birth defects account for much of the deaths among American Indian or Alaska Native, non-Hispanic infants.8

NOTE: NH = non-Hispanic origin; AIAN = American Indian or Alaska Native; API = Asian or Pacific Islander; NHOPI = Native Hawaiian or Other Pacific Islander. Infant deaths are deaths before an infant's first birthday. Race refers to the mother's race. For data through 2016, the 1977 U.S. Office of Management and Budget (OMB) standards for data on race and ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. Data from states reporting multiple races were bridged to the single-race categories of the 1977 OMB standards for comparability with other states and for trend analysis. Beginning with 2017 data, the 1997 U.S. OMB standards on race and ethnicity were used to classify persons into one of the following five racial groups: White, Black or African American, Asian, American Indian or Alaska Native, or Native Hawaiian or Other Pacific Islander. All categories are now single race. As a result, data for 2017 onward are not strictly comparable with earlier data. Data on race and Hispanic origin are collected and reported separately. Persons of Hispanic origin may be of any race.

  • The infant mortality rate decreased from 6 infant deaths per 1,000 live births in 2010 to 5 infant deaths per 1,000 live births in 2020.
  • From 2010 to 2020, the mortality rate decreased for Black, non-Hispanic; Hispanic; and White, non-Hispanic infants. The mortality rate for American Indian or Alaska Native, non-Hispanic infants did not change significantly during the period.
  • Although the mortality rate for Asian, non-Hispanic or Pacific Islander, non-Hispanic infants did not change significantly from 2010 to 2016 (4 infant deaths per 1,000 live births in 2016), trends differed for Asian, non-Hispanic and Native Hawaiian or Other Pacific Islander, non-Hispanic infants from 2017 to 2020. The mortality rate decreased from 4 infant deaths per 1,000 live births in 2017 to 3 infant deaths per 1,000 live births in 2020 for Asian, non-Hispanic infants, while the mortality rate did not change significantly for Native Hawaiian or Other Pacific Islander, non-Hispanic infants from 2017 to 2020 (7 infant deaths per 1,000 live births in 2020).
  • In 2020, the mortality rate was highest for Black, non-Hispanic infants (10 infant deaths per 1,000 live births), followed by American Indian or Alaska Native, non-Hispanic (8 infant deaths per 1,000 live births); Native Hawaiian or Other Pacific Islander, non-Hispanic (7 infant deaths per 1,000 live births); Hispanic (5 infant deaths per 1,000 live births); White, non-Hispanic (4 infant deaths per 1,000 live births); and Asian, non-Hispanic (3 infant deaths per 1,000 live births) infants.
