Maternal Mortality Ratio

Maternal Mortality is defined as a death of a woman while pregnant or within 42
days of termination of pregnancy, irrespective of the duration and site of pregnancy, from
any cause related or aggravated by the pregnancy or its management, but not from
accidental or incidental causes.
Maternal mortality ratio (usually abbreviated MMR) is the number of maternal deaths
during a given time period per 100,000 live births during the same time period
