Maternal Mortality Ratio

What does it mean ?

The Maternal Mortality Ratio (MMR) is the rate at which women die from maternal causes (any cause related to pregnancy, during childbirth, pregnancy or within 42 days of childbirth). It is measured as the number of maternal deaths per every 100,000 live births. A live birth refers to any baby that is born that shows signs of life outside of the womb. A maternal death refers to the death of woman while she is pregnant or within 42 days of childbirth, from any cause related to or aggravated by the pregnancy or its management. Maternal deaths exclude accidental or other non-related causes of death. The MMR represents the risk associated with each pregnancy and birth.

Why does it matter ?

Problems during pregnancy and childbirth are a leading cause of death and disability of women of reproductive age (15-49 years) in low income countries. This indicator acts as a record of deaths related to pregnancy and childbirth and reflects the ability of a country's healthcare system to provide safe care during pregnancy and childbirth. The Maternal Mortality Ratio is an indicator for monitoring Sustainable Development Goal 3 Health and Wellbeing Target 3.1: By 2030, reduce the global maternal mortality ratio to less than 70 per 100,000 live births.

How is it collected ?

In high income countries the data for MMR are from nationally registered deaths to women, with maternal death as the cause, then dividing by the number of registered live births. If birth and death registration is incomplete other methods are used such as a special survey or population censuses. Where there are no data, an estimate is generated from three factors: GDP, fertility rate and births attended by a skilled attendant.

Quality of data sources for maternal death (2015)

What does it mean ?

This indicator reflects coding for the source of maternal mortality data. As defined by the WHO, a value of '1' reflects good vital registration, '2' reflects other reliable source, and '3' reflects no nationally representative data.

Why does it matter ?

Part of the challenge in decreasing maternal mortality is accurately knowing when and where maternal deaths occur. This data is collected at the country level, with various sources of data between countries, including national vital registration, other reliable sources such as Demographic and Health Surveys, or no nationally representative data. This indicator reflects where such nationally representative data exist or don't exist. Until we know where all maternal deaths are occurring, we cannot make progress in reducing them.

How is it collected ?

These categories come from the World Health Organization's Trends in Maternal Mortality report. Group 1 indicates country estimates based on good civil registration data; Group 2 indicates modelled country estimates using available national data; and Group 3 indicates modelled country estimates where no national data are available on maternal mortality.
