Current Status + Progress
Maternal mortality fell by almost half between 1990 and 2015

Maternal mortality refers to deaths due to complications from pregnancy or childbirth. From 1990 to 2015, the global maternal mortality ratio declined by 44 per cent – from 385 deaths to 216 deaths per 100,000 live births, according to UN inter-agency estimates. This translates into an average annual rate of reduction of 2.3 per cent. While impressive, this is less than half the 5.5 per cent annual rate needed to achieve the three-quarters reduction in maternal mortality targeted for 2015 in Millennium Development Goal 5.

Every region has advanced, although levels of maternal mortality remain unacceptably high in sub-Saharan Africa. Almost all maternal deaths can be prevented, as evidenced by the huge disparities found between the richest and poorest countries. The lifetime risk of maternal death in high-income countries is 1 in 3,300, compared to 1 in 41 in low-income.


The number of women and girls who died each year from complications of pregnancy and childbirth declined from 532,000 in 1990 to 303,000 in 2015. These improvements are particularly remarkable in light of rapid population growth in many of the countries where maternal deaths are highest. Still, over 800 women are dying each day from complications in pregnancy and childbirth. And for every woman who dies, approximately 20 others suffer serious injuries, infections or disabilities. Almost all maternal deaths (99 per cent) occur in developing regions.

Two regions, sub-Saharan Africa and South Asia, account for 88 per cent of maternal deaths worldwide. Sub-Saharan Africans suffer from the highest maternal mortality ratio – 546 maternal deaths per 100,000 live births, or 201,000 maternal deaths a year. This is two thirds (66 per cent) of all maternal deaths per year worldwide. South Asia follows, with a maternal mortality ratio of 182, or 66,000 maternal deaths a year, accounting for 22 per cent of the global total. Furthermore, regional and global averages tend to mask  large disparities both within and between countries.


Haemorrhage remains the leading cause of maternal mortality, accounting for over one quarter (27 per cent) of deaths. Similar proportion of maternal deaths were caused indirectly by pre-existing medical conditions aggravated by the pregnancy. Hypertensive disorders of pregnancy, especially eclampsia, as well as sepsis, embolism and complications of unsafe abortion also claim a substantial number of lives.

The complications leading to maternal death can occur without warning at any time during pregnancy and childbirth. Most maternal deaths can be prevented if births are attended by skilled health personnel – doctors, nurses or midwives – who are regularly supervised, have the proper equipment and supplies, and can refer women in a timely manner to emergency obstetric care when complications are diagnosed. Complications require prompt access to quality obstetric services equipped with life-saving drugs, including antibiotics, and the ability to provide blood transfusions needed to perform Caesarean sections or other surgical interventions.

The lifetime risk of maternal death is the probability that a 15-year-old girl will die from complications of pregnancy or childbirth over her lifetime; it takes into account both the maternal mortality ratio and the total fertility rate (average number of births per woman during her reproductive years under current age-specific fertility rates). Thus, in a high-fertility setting, a woman faces the risk of maternal death multiple times, and her lifetime risk of death will be higher than in a low-fertility setting. Similar to maternal mortality ratio, the lifetime risk of maternal death varies largely across countries. In 2015, the lifetime risk of maternal death in low income countries as a whole was 1 in 41, compared to 1 in 3,300 in high-income countries. Among regions, women in sub-Saharan Africa face the highest lifetime risk (1 in 36), followed by South Asia (1 in 200).

The lifetime risk of maternal death ranges from 1 in 3,300 in high income countries to 1 in 36 in sub-Saharan Africa

The Global Strategy for Women’s, Children’s and Adolescents’ Health

May 1, 2016

The Global Strategy (2016-2030) is a roadmap to achieve right to the highest attainable standard of health for all women, children and adolescents –to transform the future and ensure every newborn, mother and child not only survives, but thrives. The new Strategy – updated through a process of collaboration with stakeholders led by WHO – builds on the success of the 2010 Strategy and its Every Woman Every Child movement as a platform to accelerate the health-related Millennium Development Goals and puts women, children and adolescents at the heart of the new UN Sustainable Development Goals.

Strategies toward ending preventable maternal mortality

Feb 10, 2015

The Ending Preventable Maternal Mortality (EPMM) targets and strategies are grounded in a human rights approach to maternal and newborn health, and focus on eliminating significant inequities that lead to disparities in access, quality and outcomes of care within and between countries. Concrete political commitments and financial investments by country governments and development partners are necessary to meet the targets and carry out the strategies for EPMM.
