Proportionate Mortality Ratio (PMR) - When we compare the proportionate mortality in one age group or occupational group to the entire population, either for deaths from all causes or from a specific cause.
Does not directly measure the risk or probability that a person in a population will die from a specific disease, as does a cause-specific mortality rate.
Differences in PMR do not reflect the risk of dying from a disease, but the differences in mortality from other causes of death.
PMR does show within any population group the relative importance of specific causes of death in the total mortality picture.
