| 1 |  | Figure 2-165 Number of deaths of U.S. residents aged 15 or older with hypersensitivity pneumonitis recorded as an underlying or contributing cause on the death certificate, 1979-1999. The annual number of hypersensitivity pneumonitis deaths generally increased during 1979-1999, from fewer than 15 per year in 1979 to 57 in 1999. Hypersensitivity pneumonitis was designated as the underlying cause of death in at least half of deaths associated with hypersensitivity pneumonitis for every year except 1982.

| 2 |  | Figure 2-168 Number of U.S. residents aged 15 or older with malignant mesothelioma listed as an underlying or contributing cause on the death certificate by type of mesothelioma, 1999. Of the 2,485 malignant mesothelioma deaths in 1999, the highest proportion was classified as an unspecified type. In nearly 95% of all deaths, malignant mesothelioma was listed as the underlying cause. (Note: The total number of deaths by subtype exceeds the number for all sites because more than one subtype was listed for some decedents.) (Source: NIOSH [2002e].)

| 3 |  | 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.)

| 4 |  | Figure 2-175 Number of deaths of U.S. residents aged 15 or older with asbestosis recorded as an underlying or contributing cause on the death certificate, 1968-1999. The number of asbestosis deaths increased from 77 in 1968 to 1,265 in 1999. During this period, asbestosis was listed each year as the underlying cause in nearly a third of all asbestosis deaths.

| 5 |  | Figure 2-178 Number of deaths of U.S. residents aged 15 or older with byssinosis recorded as an underlying or contributing cause on the death certificate, 1979-1999. The number of byssinosis deaths was fewer than 20 for each year between 1979 and 1999. During this period, byssinosis was listed as the underlying cause in 50% of the byssinosis deaths.

| 6 |  | Figure 2-183 Number of deaths of U.S. residents aged 15 or older with CWP recorded as an underlying or contributing cause on the death certificate, 1968-1999. The number of CWP deaths experienced a long-term decline during 1968-1999, from more than 2,500 deaths per year in the early 1970s and 1980s to fewer than 1,500 in the late 1990s. Although the annual number of deaths declined steadily after 1982, the proportion of deaths with CWP listed as the underlying cause on the death certificate remained fairly constant, hovering around 37% from 1980 to 1999.

| 7 |  | 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].)

| 8 |  | 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].)

| 9 |  | Figure 2-192 Number of deaths of U.S. residents aged 15 or older with silicosis recorded as an underlying or contributing cause on the death certificate, 1968-1999. The number of silicosis deaths declined sharply from 1,157 deaths in 1968 to 187 deaths in 1990. Silicosis was listed as the underlying cause of death in nearly half of all silicosis deaths from 1990 to 1999. (Source: NIOSH [2002f].)
