Work out mortality rate (crude) instantly with clear inputs, formula shown and shareable results.
Divides deaths by the mid-period population to give the crude death rate, expressed per the chosen population base.
Crude mortality rate
Crude rate = deaths in the period / mid-period population, expressed per 1,000 or per 100,000
It makes no allowance for age structure, so an older population always looks worse than a younger one.
Age-standardised rates when comparing populations, or age-specific rates when the pattern matters.
