MMWR Morb Mortal Wkly Rep. 1993 Nov 26;42(46):891, 897-900.
In 1991, 2,169,518 deaths were registered in the United States--21,055 more than in 1990 and the most ever recorded. Despite this increase, the overall age-adjusted death rate was 513.7 per 100,000 population, the lowest ever recorded. Provisional data for 1992 indicate that the death rate continued to decline through 1992. As in previous years, nearly two thirds of deaths in 1991 were caused by the first three leading causes of death (i.e., heart disease, cancer, and stroke). This report summarizes mortality data for 1991 and compares patterns with 1990.
1991年，美国登记的死亡人数为2169518人，比1990年多21055人，创历史最高纪录。尽管有所增加，但总体年龄调整死亡率为每10万人513.7人，为历史最低。1992年的初步数据表明，死亡率在1992年持续下降。与往年一样，1991年近三分之二的死亡是由前三大主要死因（即心脏病、癌症和中风）导致的。本报告总结了1991年的死亡率数据，并与1990年的模式进行了比较。
