| 1 |  | Figure 2-172 Number of deaths of U.S. residents aged 15 or older with pneumoconiosis recorded as an underlying or contributing cause on the death certificate, 1968-1999. During 1968-1999, deaths from asbestosis increased over time, whereas deaths from CWP decreased. Deaths from all pneumoconioses are shown at the top of each stacked bar. The bars slightly overstate the numbers because a small fraction of deaths was associated with more than one type of pneumoconiosis. (Note: Byssinosis data were not available before 1979. Also note that the sum of deaths for various types of pneumoconiosis (N=123,091) exceeds the total number of pneumoconiosis deaths (N=121,982) because some decedents had more than one type of pneumoconiosis recorded on their death certificates.)

| 2 |  | Figure 2-173 Distribution of pneumoconiosis deaths in U.S. residents aged 15 or older by sex, 1990-1999. Men accounted for more than 98% of the 31,452 decedents with any type of pneumoconiosis during 1990-1999. However, an unusually large proportion of byssinosis decedents (33%) were female. (Note: The sum of deaths for various types of pneumoconiosis exceeds the total number of pneumoconiosis deaths because some decedents had more than one type of pneumoconiosis.)

| 3 |  | Figure 2-174 Distribution of pneumoconiosis deaths in U.S. residents aged 15 or older by race, 1990-1999. During 1990-1999, decedents with pneumoconiosis were predominantly white. Less than 4% of CWP deaths occurred among nonwhite residents. By contrast, 15% of silicosis decedents were nonwhite. (Note: The sum of deaths for various types of pneumoconiosis exceeds the total number of pneumoconiosis deaths because some decedents had more than one type of pneumoconiosis.)

| 4 |  | Figure 2-186 Number of deaths of U.S. residents aged 15 or older with unspecified/other pneumoconiosis recorded as an underlying or contributing cause on the death certificate, 1968-1999. The number of unspecified/other pneumoconiosis deaths declined sharply from a high of 1,524 in 1972 to fewer than 400 per year in 1983 and thereafter. The proportion of these deaths in which unspecified/other pneumoconiosis was listed as the underlying cause hovered around 34%. (Source: NIOSH [2002f].)

| 5 |  | Figure 2-187 Age-adjusted mortality rates for unspecified/other pneumoconiosis in U.S. residents aged 15 or older by State, 1990-1999. During 1990-1999, West Virginia had the highest mortality rates for unspecified/other pneumoconiosis-more than 20 times the U.S. rate of 1.59 per million. High rates were observed among other Appalachian and Western mining States, ranging from two to nine times the U.S. rate. (Source: NIOSH [2002f].)

| 6 |  | Figure 2-188 PMRs and 95% confidence intervals for unspecified/other pneumoconiosis in U.S. residents aged 15 or older by industry and occupation, adjusted for age, race, and sex, 1990-1999. Coal and metal mining industries were associated with elevated mortality from unspecified/other pneumoconiosis (as these industries were also associated with high CWP mortality). In addition, the glass and glass products industry had a significantly high PMR. Among occupations, mining machine operators and supervisors, extractive occupations were associated with the highest PMRs, followed by welders and cutters and electricians. (Note: This figure presents the highest significant PMRs based on 10 or more deaths.) (Source: NIOSH [2002f].)
