The 1980 National Center for Health Statistics life tables for the U.S. black and white populations reveal a difference in life expectancy of 7 years between black and white males and 6 years between black and white females. Using cause-substituted life tables, we show that a number of causes of death contribute to the difference. The largest contributors are cardiovascular disease for both sexes and homicide and cancer for males.
1980年美国国家卫生统计中心发布的美国黑人和白人人口寿命表显示，黑人男性与白人男性的预期寿命相差7岁，黑人女性与白人女性相差6岁。通过使用病因替代寿命表，我们发现多种死因导致了这一差异。对两性而言，最大的死因贡献因素是心血管疾病，对男性来说则是 homicide（此处可能有误，推测为“他杀”，原文可能是“homicide”拼写错误，正确应该是“homicide”，意为“他杀”）和癌症。
