Maternal Mortality Ratio (MMR) Calculator

The Maternal Mortality Ratio (MMR) is a demographic indicator that measures the number of maternal deaths per 100,000 live births during a given time period. It is commonly used to assess the quality of maternal healthcare and the overall health of a population. The formula calculates the MMR by dividing the number of maternal deaths by the number of live births and then multiplying the result by 100,000. This provides a standardized measure for comparing maternal mortality rates between different populations or time periods.

Parameter usage:


Data validation

The number of maternal deaths should be greater than or equal to 0, and the number of live births should be greater than 0.
