Proportionate mortality ratio Defined
The following is in context to Worker Health, because it's common for a single word to have multiple meanings you will find additional research links near the bottom of the page.
"The proportionate mortality ratio (PMR) is defined as the observed number of deaths with the condition of interest (mentioned as either underlying or contributing) in an industry/occupation from selected States and years, divided by the expected number of deaths with that condition. The expected number of deaths is the total number of deaths in the industry or occupation classification of interest multiplied by a proportion. This proportion is defined as the number of cause-specific deaths for the condition of interest in all industries/occupations divided by the total number of deaths in all industries/occupations. The PMRs in this report have been internally adjusted by 5-year age groups (i.e., 15–19, 20–24, . . . , 110–114, and 115 years and over), sex, and race (i.e., white, black, and all other). Confidence intervals were calculated assuming Poisson distribution of the data. A PMR greater than 1.0 indicates that more deaths were associated with the condition in an occupation or industry than expected. This report includes only those industries/occupations with 5 or more decedents with the condition and a lower 95% confidence limit exceeding 1.0."
