It has been shown that mothers between ages 18 and 44 who did not complete high school had a 5% increase in maternal mortality versus women who completed high school.[32] By completing primary school, 10% of girls younger than 17 years old would not get pregnant and 2/3 of maternal deaths could be prevented.[33] Secondary education, university schooling, would only further decrease rates of pregnancy and maternal death.

Of note, higher education still does not improve the racial differences in maternal mortality and is not protective for Black mothers in the way they are for White mothers. It has been found that Black mothers with a college education have greater maternal mortality than White mothers with less than a high school education.[34]

Young adolescents are at the highest risk of fatal complications of any age group.[35] This high risk can be accounted for by various causes such as the likelihood of adolescents giving birth for the first time compared to women in older age groups.[36] Other factors that also may lead to higher risk among this age group includes lower economic status and education.[37] While adolescents face a higher risk of maternal mortality, a study conducted between 2005 and 2014 found that the rate of maternal mortality was higher among older women.[38] Additionally, another study found that the rate is higher specifically among women aged 30 years or older.[36]

There are significant racial disparities in maternal deaths within the United States.[42][43][5][4][44]

In 2023, Asian women had the lowest maternal death rate in the United States, with a death rate of 11 per 100,000. Hispanic women had the second lowest maternal death rate, at 12 per 100,000. White women had a death rate of 14.5 per 100,000. Black women's maternal death rate was slightly greater than 50 per 100,000.[5]
