Mortality Rate Calculator
Crude, cause-specific, infant and maternal mortality rates with CIs.
Enter your values to see the result.
Crude, cause-specific and age-specific rates use the mid-year population; infant, neonatal and under-5 rates use live births (per 1,000) and the maternal mortality ratio uses live births (per 100,000). Confidence intervals use exact (Clopper–Pearson or Poisson) methods. Rates are only comparable between populations with similar age structures unless you standardize them.

How to use the Mortality Rate Calculator
Crude, cause-specific, infant and maternal mortality rates with CIs.
- 1 Choose the type of rate.
- 2 Enter the deaths and the population, live births or total deaths.
- 3 Read the rate per the standard multiplier with its interval.
Example and practical tips
820 deaths in a mid-year population of 104,000 is a crude death rate of 7.88 per 1,000.
Frequently asked questions
Why can crude death rates mislead?
Older populations have more deaths. Compare populations with age-specific or age-standardized rates.
Is maternal mortality a rate or a ratio?
It is usually a ratio: maternal deaths per 100,000 live births, because live births stand in for pregnancies.
