Source: For these charts, death certificates for decedents that died in one of the 27 U.S. states between 1984 and 1998 were the source of age (ages 18-90), race (black, white), gender, usual occupation and industry and multiple cause-of-death. PMRs were calculated with all races and genders combined to evaluate the mortality patterns for 22 site-specific cancers and 17 cardiovascular, neurodegenerative, diabetes, and renal diseases for the larger industries in each of eight sectors: agriculture, forestry, fishing; mining; construction; manufacturing, wholesale & retail trade; transportation, warehousing & utilities; healthcare & social assistance; and services. If a PMR is greater than 100 in the chart, it is elevated; if less, it is said to be decreased. User may consult crosswalks for ICD9 and 1980 Census industry category codes (Chronic Disease and Industry Categories).
PMRs are computed when the data for the population at risk are not available and death rates cannot be computed. Thus the PMRs presented indicate whether the proportion of deaths due to a specific cause appears to be high or low for a particular industry compared to all industries. The 95% confidence intervals (95% CI) were computed based on the Poisson distribution if the observed number of deaths was 1000 or less; otherwise, test-based CIs were computed based on the Mantel and Haenszel chi square test.
