Maternal Mortality in the United States: Understanding a Persistent Crisis

Maternal mortality in the United States is a public health crisis that researchers, clinicians, and policymakers have struggled to address for decades. The United States has consistently higher rates of maternal death than peer nations, and the gap has widened over time rather than narrowed. Understanding the scope of the problem, its causes, and the disparities that run through it is essential for any serious policy response. The definition of maternal mortality typically includes deaths occurring during pregnancy or within 42 days of the end of pregnancy from causes related to or aggravated by the pregnancy. The Centers for Disease Control and Prevention tracks these deaths through the Pregnancy Mortality Surveillance System, which relies on death certificates and supplemental data. Rates vary by year and by how deaths are classified, but the United States consistently reports rates between 20 and 30 maternal deaths per 100,000 live births, compared to single-digit rates in many European countries and Canada. Racial disparities are among the most striking features of maternal mortality in the United States. Black women die from pregnancy-related causes at rates more than two to three times higher than white women. This disparity persists even after controlling for income, education, access to prenatal care, and other socioeconomic factors. Researchers have increasingly focused on the role of structural racism in shaping these outcomes, including the documented tendency of healthcare providers to underestimate or dismiss pain and symptoms in Black patients, the cumulative physiological effects of chronic stress related to discrimination, and differential access to high-quality maternity care. The leading causes of maternal death have shifted over time. Hemorrhage and embolism remain significant, but mental health conditions, including suicide and overdose related to substance use disorders, now account for a substantial share of pregnancy-related deaths. The expansion of the definition to include deaths in the year following delivery has revealed the importance of postpartum mental health as a maternal health issue. Cardiovascular conditions are also increasing as a share of maternal deaths, partly because more women with chronic conditions are becoming pregnant. Geographic variation is substantial. Rural areas have higher maternal mortality rates than urban areas, driven by a combination of hospital closures, reduced access to obstetric specialists, and longer transport times in emergencies. Several states in the South and Midwest report rates well above the national average. State-level maternal mortality review committees, which examine individual deaths to identify preventable factors, have found that more than half of all pregnancy-related deaths are preventable. Prenatal care access is a key structural factor. Women who receive no prenatal care or late prenatal care face substantially higher risks than those who receive early and consistent care. Barriers to prenatal care include lack of insurance, inability to take time off work for appointments, geographic distance from providers, and implicit or explicit bias in healthcare settings. Medicaid expansion under the Affordable Care Act increased insurance coverage among low-income pregnant women, which researchers associate with improved access to care and modest improvements in some outcomes. The postpartum period receives less policy attention than pregnancy itself, but evidence increasingly points to the vulnerability of this window. Medicaid coverage in most states ends 60 days after delivery, leaving women at risk precisely when postpartum depression, eclampsia complications, and other conditions are most likely to emerge. Federal legislation extended Medicaid postpartum coverage to 12 months in states that chose to adopt the option, representing a significant policy shift that researchers are tracking for effects on outcomes. Midwifery and birth center models of care have received attention as alternatives that may be associated with better outcomes for low-risk pregnancies, particularly in terms of cesarean rates and maternal satisfaction. Some researchers argue that the dominance of highly medicalized birth in the United States may itself contribute to complications by increasing intervention rates. Others emphasize that the United States serves a higher-risk population than many peer nations, making direct comparisons difficult. Hospital quality variation is another lever. Research consistently finds that outcomes differ substantially across facilities, even within the same geographic area. Women who deliver at hospitals with higher volume and more specialized resources have better outcomes for high-risk pregnancies. Systems of regionalized care that route high-risk pregnancies to specialized centers have shown promise in improving outcomes, but geography and transportation remain barriers. Addressing maternal mortality requires action across multiple systems simultaneously: expanding insurance coverage and postpartum care, training providers to recognize and combat implicit bias, strengthening rural maternity care infrastructure, improving surveillance and data quality, and investing in community-based support for new parents. The scale of the problem relative to peer nations is not inevitable but reflects choices about how the healthcare system is structured and whom it prioritizes.
