This report discusses the rationale for and implications of the implementation of a new population standard for the age standardization (age adjustment) of death rates. The new standard is based on the year 2000 population and beginning with data year 1999, will replace the existing standard based on the 1940 population. This report also includes a technical discussion of direct and indirect standardization and statistical variability in age-adjusted death rates. Currently, at least three different standards are used among Department of Health and Human Services agencies. Implementation of the year 2000 standard will reduce confusion among data users and the burden on State and local agencies. Use of the year 2000 standard will also result in age-adjusted death rates that are substantially larger than those based on the 1940 standard. Further, the new standard will affect trends in age-adjusted death rates for certain causes of death and will narrow race differentials in age-adjusted death rates. Although age standardization is an important and useful tool, it has some limitations. As a result the examination of age-adjusted death rates should be the beginning of an analysis strategy.
本报告讨论了实施死亡率年龄标准化（年龄调整）新人口标准的基本原理及其影响。新的标准基于2000年人口数据，从1999年数据年开始，将取代现有的基于1940年人口数据的标准。本报告还包括对直接和间接标准化以及年龄调整死亡率的统计变异性的技术讨论。目前，美国卫生与公众服务部各机构至少使用三种不同的标准。实施2000年标准将减少数据使用者之间的混淆以及州和地方机构的负担。使用2000年标准还将导致年龄调整死亡率大幅高于基于1940年标准的死亡率。此外，新的标准将影响某些死因的年龄调整死亡率趋势，并缩小年龄调整死亡率中的种族差异。尽管年龄标准化是一个重要且有用的工具，但它也有一些局限性。因此，对年龄调整死亡率的审查应作为分析策略的起点。
