Other data were obtained from the National Center for Health Statistics, the Department of Labor, the Social Security Administration, the Mine Safety and Health Administration, the Occupational Safety and Health Administration, the Bureau of Mines, and the Association of Occupational and Environmental Clinics. The organization of the 1994 WoRLD Surveillance Report differs from earlier editions. It is divided into 11 major sections. The first ten sections are specific to selected occupational lung diseases or conditions, summarizing mortality and morbidity data, and other available information, such as occupational exposures or numbers of workers at risk. The remaining section provides data from the Association of Occupational and Environmental Clinics database.
Most sections contain an initial group of figures, followed by data tables.
The 1994 WoRLD Surveillance Report contains major additions, both in the addition of previously unreported data such as that from the National Health Interview Survey and the Association of Occupational and Environmental Clinics, and in supplementing the data with selected statistical measures, such as proportionate mortality ratios, both crude and age-adjusted rates at national and state levels, and years of potential life lost to age 65 and to life expectancy.
