Abstract

Are mortality and life expectancy differences by socioeconomic groups increasing in the United States? Using a unique data set matching administrative and survey data, this study explores trends in these differentials by lifetime earnings for the 1983-2003 period. Results indicate a consistent increase in mortality differentials across sex and age groups. The study also finds a substantial increase in life expectancy differentials by lifetime earnings: the top-to-bottom quintile premium increased 30 percent for men and almost doubled for women. These results complement recent research to point to almost five decades of increasing differential mortality in the United States.

摘要

美国的社会经济群体的死亡率和预期寿命差异是否在增加？本研究使用一个独特的匹配行政和调查数据的数据集，探讨了 1983-2003 年期间按终身收入划分的这些差异的趋势。结果表明，不同性别和年龄组的死亡率差异持续增加。研究还发现，终身收入差异导致的预期寿命差异也在大幅增加：男性的最高五分位数与最低五分位数之间的预期寿命差距增加了 30%，女性的差距几乎增加了一倍。这些结果补充了最近的研究，表明美国的死亡率差异在过去近 50 年中一直在增加。
