proportional mortality ratio

Show Summary Details

Quick Reference


A useful, frequently used but often poorly understood indicator of aspects of population health. The PMR is the number of observed deaths from a specified cause in a defined population divided by the number of deaths that would be expected in a standard population, with both numbers expressed as a proportion of all deaths. PMR does not require data on the age composition of the population (unlike the standardized mortality ratio). The “standard population” can be any arbitrarily selected suitable one. The PMRs of specific occupational groups are sometimes used to determine whether their mortality experience differs significantly from that of the general population, justifying further investigation.
