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.
