Tenth revision U.S. mortality rates for use with the NIOSH Life Table Analysis System.

OBJECTIVE The objective of this study was to update rate files for the NIOSH Life Table Analysis System for Personal Computers (PC LTAS) reflecting the newly adopted tenth revision changes to the International Classification of Diseases. METHODS PC LTAS allows researchers to conduct comparative mortality and morbidity analyses for the purpose of identifying disease-exposure associations using person-time-at-risk for age, race, sex, and calendar time-specific reference rates from 1940. Previously available through 1998, files for the United States and individual states were updated through 2004 using uncensored population data. Tenth revision causes were added if compatible with earlier NIOSH death categories, based on revisions 5 through 9. A few new cause categories were added. RESULTS The resulting NIOSH categories are described for two new U.S. rate files: 1960 through 2004 and 1940 through 2004. CONCLUSION The new U.S. rate files are available online or on request.
