Name Maternal Mortality Ratio per 100,000 (MDG 5.1)
Definition The number of maternal deaths related to childbearing divided by the number of live births in that year. Maternal death is the death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes. (WHO standard def)
Calculation/Formula "Recorded (or estimated) number of maternal deaths / Total recorded (or estimated) number of live births in the same period x 100,000."
Unit of Measure Ratio
Assumptions Should be measured over 5 -10 year aggregate periods and reported with 95% confidence intervals to minimise instability due to the small number of events. Note that this measure is often confused with Maternal Mortality Rate which uses the population of women of child bearing age (usually 15-44 years) as a denominator and is therefore a less direct measure of risk arising from pregnancy and childbirth.
Limitations Measurement requires information on pregnancy status, timing of death (during pregnancy, childbirth, or within 42 days of termination of pregnancy), and cause of death.
Purpose/Rationale Complications during pregnancy and childbirth are a leading cause of death and disability among women of reproductive age in developing countries. The maternal mortality ratio represents the risk associated with each pregnancy, i.e. the obstetric risk.

Preferred Data Sources The primary source of cause-specific mortality data should be vital registration including Cause of death data collected through the health dept and/or civil registry and verified for completeness
Alternative_Data Sources Census
Census - HIES - DHS tag Census/DHS
Primary Data Collection System National Administrative Database - Health Information Management Systems (HIS)
Frequency of Data Collection Annual (aggregated over multiple years)
Other agencies countries_ must report to: CHIPS

Comments / Regional Trend Analysis As countries improve vital statistics and civil registration systems, there may be some increases in published measures of mortality (such as IMR) due to improvements in reporting rather than a true increase in mortality rate. Care must be taken in inter
Notes Health surveys are unreliable as a data collection system given small incidence.
