1		Figure 4-19 Numbers of deaths, crude mortality rates, and age-adjusted mortality rates for U.S. residents aged 15 or older with coal workers' pneumoconiosis recorded as an underlying or contributing cause on the death certificate, 1968-1999. After passage of the Federal Coal Mine Health and Safety Act of 1969, an increase occurred in the number and rate of deaths reported with coal workers' pneumoconiosis (black lung) recorded on the death certificate. The number and rate of these deaths were at their lowest in 1999, the last year for which data are currently available. The number decreased from 2,870 in 1972 to 1,003 in 1999. In 1972, the crude and age-adjusted mortality rates were 18.9 and 21.2 per million population, respectively. Both rates declined to 4.7 per million in 1999. (Note: Age-adjusted mortality rates are standardized to the year 2000 standard population.) (Sources: NCHS [2002]; NIOSH [2002].)
