Maternal death or maternal mortality is defined in slightly different ways by several different health organizations. The World Health Organization (WHO) defines maternal death as the death of a pregnant mother due to complications related to pregnancy, underlying conditions worsened by the pregnancy or management of these conditions. This can occur either while she is pregnant or within six weeks of resolution of the pregnancy. The CDC definition of pregnancy-related deaths extends the period of consideration to include one year from the resolution of the pregnancy. Pregnancy associated death, as defined by the American College of Obstetricians and Gynecologists (ACOG), are all deaths occurring within one year of a pregnancy resolution. Identification of pregnancy associated deaths is important for deciding whether or not the pregnancy was a direct or indirect contributing cause of the death. There are two main measures used when talking about the rates of maternal mortality in a community or country. These are the maternal mortality ratio and maternal mortality rate, both abbreviated as "MMR". By 2017, the world maternal mortality rate had declined 44% since 1990; however, every day 808 women die from pregnancy or childbirth related causes. According to the United Nations Population Fund (UNFPA) 2017 report, about every 2 minutes a woman dies because of complications due to childbirth or pregnancy. For every woman who dies, there are about 20 to 30 women who experience injury, infection, or other birth or pregnancy-related complications. UNFPA estimated that 303,000 women died of pregnancy or childbirth-related causes in 2015. The WHO divides causes of maternal deaths into two categories: direct obstetric deaths and indirect obstetric deaths. Direct obstetric deaths are causes of death due to complications of pregnancy, birth or termination. For example, these could range from severe bleeding to obstructed labor, for which there are highly effective interventions. Indirect obstetric deaths are caused by pregnancy interfering or worsening an existing condition, like a heart problem. As women have gained access to family planning and skilled birth attendant with backup emergency obstetric care, the global maternal mortality ratio has fallen from 385 maternal deaths per 100,000 live births in 1990 to 216 deaths per 100,000 live births in 2015. Many countries halved their maternal death rates in the last 10 years. Although attempts have been made to reduce maternal mortality, there is much room for improvement, particularly in low-resource regions. Over 85% of maternal deaths are in low-resource communities in Africa and Asia. In higher resource regions, there are still significant areas with room for growth, particularly as they relate to racial and ethnic disparities and inequities in maternal mortality and morbidity rates. Overall, maternal mortality is an important marker of the health of the country and reflects on its health infrastructure. Lowering the amount of maternal death is an important goal of many health organizations worldwide.

=== Direct obstetric deaths ===
==== Overview ==== Direct obstetric deaths are due to complications of pregnancy, birth, termination, or complications arising from their management. The causes of maternal death vary by region and level of access. According to a study published in the Lancet which covered the period from 1990 to 2013, the most common causes of maternal death world-wide are postpartum bleeding (15%), complications from unsafe abortion (15%), hypertensive disorders of pregnancy (10%), postpartum infections (8%), and obstructed labor (6%). Other causes include blood clots (3%) and pre-existing conditions (28%).
==== Descriptions by condition ==== Postpartum bleeding happens when there is uncontrollable bleeding from the uterus, cervix, or vaginal wall after birth. This can happen when the uterus does not contract correctly after birth, there is leftover placenta in the uterus, or there are cuts in the cervix or vagina from birth. Hypertensive disorders of pregnancy happen when the body does not regulate blood pressure correctly. In pregnancy, this is due to changes at the level of the blood vessels, likely because of the placenta. This includes medical conditions like gestational hypertension and pre-eclampsia. Postpartum infections are infections of the uterus or other parts of the reproductive tract after the resolution of a pregnancy. They are usually bacterial and cause fever, increased pain, and foul-smelling discharge. Obstructed labor happens when the baby does not properly move into the pelvis and out of the body during labor. The most common cause of obstructed labor is when the baby's head is too big or angled in a way that does not allow it to pass through the pelvis and birth canal. Blood clots can occur in different vessels in the body, including vessels in the arms, legs, and lungs. They can cause problems in the lungs and travel to the heart or brain, thereby leading to complications.
