About Mortality Rate (Crude) Calculator

Divides deaths by the mid-period population to give the crude death rate, expressed per the chosen population base.

Formula

Crude mortality rate

Crude rate = deaths in the period / mid-period population, expressed per 1,000 or per 100,000

Worked example

With the default values below, Mortality Rate (Crude) Calculator returns Crude mortality rate of 8.500. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why is it called crude?

It makes no allowance for age structure, so an older population always looks worse than a younger one.

What should be used instead?

Age-standardised rates when comparing populations, or age-specific rates when the pattern matters.
