Pregnancy-Associated Death (PAD): The death of a woman from any cause, while pregnant or within one (1) year of being pregnant, regardless of the duration and location of the pregnancy. This represents the total number of maternal deaths within the state of Idaho and is subdivided into two (2) categories:
- Pregnancy-Associated but not Related Death: A pregnancy-associated death due to a non-pregnancy related cause.
- Pregnancy-Related Death (PRD): A pregnancy-associated death resulting from one of the following:
- Complications of the pregnancy itself.
- A chain of events initiated by the pregnancy.
- Aggravation of an unrelated condition by the physiological effects of pregnancy.
Pregnancy-Related Mortality Ratio (PRMR): Used by most state maternal mortality review committees to calculate the number of pregnancy-related deaths (women who were pregnant at time of death or within one (1) year of being pregnant) per 100,000 live births
Numerator: Number of pregnancy-related deaths per year
Denominator: Number of live births per year

Healthy People 2030 Initiative (MICH-04) Obstetrics Caused Pregnancy-Related Ratio: Used by the U.S. Department of Health and Human Services as a quantitative measure of the number of pregnancy-related obstetric caused deaths per 100,000 live births. This counting methodology aligns with the international definition of maternal death.
- Numerator: Number of female deaths due to obstetric causes (ICD-10 codes: A34, O00-O95, O98-O99) while pregnant or within forty-two (42) days of being pregnant.
- Denominator: Number of live births per year.
