Measuring socioeconomic mortality differentials over time

Using 1973 Current Population Survey data matched to 1973-1978 Social Security mortality records, this study measures the relationship between the income and education of men and their subsequent mortality. The estimated relationships are compared with socioeconomic mortality differentials found by Kitagawa and Hauser in their study of 1960 census-death certificate matched data. The comparison suggests that there has been no improvement in the relative mortality experience of low socioeconomic status men. More generally, the article discusses how Social Security data could be used to monitor, on a continual basis, our progress toward eradicating signficant mortality differentials in the United States.
