This paper evaluates the quality of vital statistics and census data for estimating African-American mortality over a period of six decades. The authors employ intercensal cohort comparisons and extinct generation estimates to demonstrate that conventionally constructed African-American death rates may be seriously flawed as early as age 50. Using the crude death rate at ages 50+ for 1978-1982 in conjunction with estimated growth rates and two model life table systems, the authors estimate black age-specific death rates in 1978-1982. These results suggest that if a racial crossover in death rates occurs, the age pattern of mortality among African-Americans must be far outside the range observed in populations with more accurate data.
本文评估了六十年间用于估算非裔美国人死亡率的人口动态统计数据和人口普查数据的质量。作者采用两次人口普查之间的队列比较和灭绝世代估计法,以证明传统构建的非裔美国人死亡率早在50岁时可能就存在严重缺陷。作者将1978 - 1982年50岁及以上人群的粗死亡率与估计增长率以及两种模型生命表系统相结合,估算了1978 - 1982年按年龄划分的黑人死亡率。这些结果表明,如果死亡率出现种族交叉现象,那么非裔美国人的死亡率年龄模式必定远远超出在数据更准确的人群中所观察到的范围。
