Notice to Readers: National Occupational Respiratory Mortality System
The National Occupational Respiratory Mortality System (NORMS), a recent addition to CDC's website, is a data storage and data retrieval system developed and maintained by the National Institute for Occupational Safety and Health, Division of Respiratory Disease Studies. The system contains national mortality data obtained annually since 1968 from the National Center for Health Statistics for asthma, chronic obstructive pulmonary disease, lung cancer, malignant mesothelioma, pneumoconiosis, tuberculosis, and other respiratory diseases and conditions.
This system offers a range of search options for generating tables, charts, and maps of the number of deaths, crude mortality rates, age-adjusted mortality rates, and years of potential life lost at national, state, and county levels for U.S. residents by age, race, and sex. In addition, users of NORMS can tabulate proportionate mortality ratios by usual industry and/or occupation at national and state levels.
NORMS can be useful for all persons interested in finding data on work-related lung disease mortality by time and place. NORMS data are available at http://webappa.cdc.gov/ords/norms.html.
