Maternal Mortality Rates in the United States, 2020

23 Feb 2022

This report presents maternal mortality rates for 2020 based on data from the National Vital Statistics System. A maternal death is defined by the World Health Organization as, “the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and the site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes” (1). Maternal mortality rates, which are the number of maternal deaths per 100,000 live births, are shown in this report by age group and race and Hispanic origin. In 2020, the maternal mortality rate for non-Hispanic Black women was 55.3 deaths per 100,000 live births, 2.9 times the rate for non-Hispanic White women (19.1) (Figure 1 and Table). Rates for non-Hispanic Black women were significantly higher than rates for non-Hispanic White and Hispanic women. The increases from 2019 to 2020 for non-Hispanic Black and Hispanic women were significant. The observed increase from 2019 to 2020 for non-Hispanic White women was not significant. Rates increased with maternal age. Rates in 2020 were 13.8 deaths per 100,000 live births for women under age 25, 22.8 for those aged 25–39, and 107.9 for those aged 40 and over (Figure 2 and Table). The rate for women aged 40 and over was 7.8 times higher than the rate for women under age 25. Differences in the rates between age groups were statistically significant. Among age groups, the increase in the rates between 2019 and 2020 for women aged 25–39 and 40 and over were statistically significant.
