Mortality reporting in SSA linked data: preliminary results.

The earnings and benefit data of the Social Security Administration represent a fairly large and balanced sample of present and past wage earners nationwide. Since the incentives for reporting deaths to the Social Security Administration mean that deaths are reported as a matter of course, this data base serves as an interesting prospect for examining problems of differential mortality. Variables available include age, race, sex, industry, and place of employment. To check on the coverage and content differences between social security and death certificate data, a sample study is being undertaken that links the two sources for 1975 decedents. This article provides a preliminary examination of the differences between the presumably complete frame of death certificates and the social security record data. Related efforts now in progress to improve available information for use in further mortality research are also discussed briefly.
