Pregnancy‑related deaths remain a critical public health concern worldwide. This overview explains how pregnancy‑related mortality is defined, how many women die during or after pregnancy in different regions, and the leading causes behind these deaths. We examine evidence‑based risk factors, disparities by race and geography, and prevention strategies that can improve outcomes. The content focuses on long‑standing patterns and measurable progress, intended as a durable reference for understanding the scope and drivers of maternal mortality and the steps that can reduce it.
What Counts as a Pregnancy‑Related Death
How Health Agencies Define These Deaths
A pregnancy‑related death is defined as a death while pregnant or within one year of pregnancy结局, resulting from complications of the pregnancy or its management, not from accidental or incidental causes. This definition, used by the World Health Organization and many national agencies, helps ensure consistency in tracking and comparing data. Accurately identifying the underlying cause requires medical certification and review by multidisciplinary committees to distinguish deaths directly linked to pregnancy from those due to unrelated conditions. Clear definitions support reliable measurement of trends, equity in care, and targeted prevention efforts.
Global Burden of Pregnancy‑Related Deaths
Regional Patterns and Long‑Term Trends
Globally, the estimated annual number of pregnancy‑related deaths has declined over recent decades, yet substantial disparities remain. Most deaths occur in low‑ and middle‑income regions where access to skilled birth attendance, emergency obstetric care, and timely treatment for complications is limited. In sub‑Saharan Africa and parts of South Asia, the risk of dying due to pregnancy‑related causes remains disproportionately high. International health goals emphasize improving data quality, expanding coverage of maternal health services, and addressing social determinants of health to accelerate progress.

Leading Causes of Pregnancy‑Related Death Among Women
Medical Drivers and Preventable Factors
The major causes of pregnancy‑related mortality are severe bleeding, infections, hypertensive disorders such as preeclampsia and eclampsia, obstructed labor, and unsafe abortion. Many of these deaths could be prevented with access to antenatal care, skilled birth attendants, emergency obstetric interventions, and timely treatment for complications. In some settings, gaps in family planning, delays in seeking care, and challenges in transportation and health system capacity contribute to adverse outcomes. Understanding these drivers supports focused interventions, from community‑based education to strengthened referral systems.
Risk Factors and Disparities
Social, Structural, and Clinical Influences
Women face increased risk of pregnancy‑related death due to a combination of clinical, social, structural, and geographic factors. Key risk factors include:
- Younger or older maternal age
- Preexisting medical conditions such as HIV, malaria, or anemia
- Limited access to skilled maternal health care and family planning
- Rural residence or displacement due to conflict or climate events
- Socioeconomic disadvantage and systemic inequities in care
Racial and ethnic disparities within countries also persist, with some groups experiencing higher mortality rates even in high‑income settings. These patterns reflect unequal distribution of resources, bias in care, and social determinants that influence exposure to risk and quality of care.
Prevention Strategies and Health System Measures
What Works to Reduce Maternal Mortality
Effective prevention combines strong health systems with community‑level approaches. Evidence‑based measures include:
- Antenatal care visits to identify and manage risks early
- Skilled birth attendance and availability of emergency obstetric care
- Family planning and spacing of pregnancies
- Rapid management of obstetric complications, such as hemorrhage and sepsis
- Safe abortion services and postpartum care
Investing in midwifery, data systems, transportation, and referral networks can improve timely care. Public health programs that address poverty, education, and gender equality further reduce underlying risks. Continuous monitoring and responsive health policies help ensure that progress reaches all women.
Data, Limitations, and How Trends Are Interpreted
Understanding Uncertainty and Comparisons
Estimates of pregnancy‑related deaths are derived from vital registration, surveys, and modeling, with varying levels of completeness and methodological differences across regions. Underreporting, misclassification, and changes in case definitions can affect year‑to‑year comparisons. When comparing countries or time periods, it is important to consider population size, quality of data, and health system context. Despite limitations, consistent use of standard definitions and improved data collection enhance the reliability of trends and support informed decision‑making.
Key Terms and Clarifications
Clarifying Concepts Used in Maternal Mortality Discussions
