Definitions related to maternal and pregnancy-related mortality.

Maternal death	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.
Pregnancy-related death	Death of a woman while pregnant or within 42 days of termination of pregnancy, irrespective of the cause of death.
Late maternal death	Death of a woman from direct or indirect obstetric causes, more than 42 days, but less than one year after termination of pregnancy.
PM	Proportion of maternal deaths among deaths of women of reproductive age.
Pregnancy-related PM	Proportion of pregnancy-related deaths among deaths of women of reproductive age.
Maternal mortality ratio (MMR)	Number of maternal deaths per 100,000 live births.
Maternal mortality rate	The ratio of maternal deaths to the women-years of exposure for the age group 15–49.
Life time risk	The probability of a 15-year-old woman eventually dying from a maternal cause, assuming she is subjected throughout her lifetime to the risks of maternal death as estimated for that country-year. (17)
Annual (continuous) rate of reduction (ARR)	Measure of relative decline per year, defined as ARR = log(MMRt2/MMRt1)/(t1−t2) where t1 and t2 refer to different years with t1 < t2.
