Baseline Data for the Longitudinal Study of Aging

摘要 该项目将完成一个纵向数据基础设施，包括1940年以来的大部分美国人口 到2020年。连接的基础设施目前包括1940年和2000-2020年人口普查的数据，以及 很快将包括1960-1990年人口普查的数据。目前的项目将纳入1950年的人口普查 并加强1940年的人口普查。这些新数据将为当今大多数最古老的生物提供基线观测 美国人。建成后，整个1940-2020年的基础设施将成为一个巨大的多用途资源 实现了一系列新的发现和应用。 为实现这一目标，我们将开展三项重点工作：(1)将1950年人口普查受访者与更广泛的 基础设施，(2)使用新技术提高目前可用于以下方面的联系的覆盖率和准确性 1940年的人口普查受访者，以及(3)使用受限的社会保障管理局文件添加新信息 受访者的确切出生日期，出生在美国的人的出生县，以及死者的死亡日期。 随着1940年和1950年相关病例的增加，人口健康研究人员将能够使用这些 分析过去一个世纪数亿美国人的生命轨迹的数据。 研究人员将能够纳入有关早期生活和祖先经历的信息--例如父母 经济地位、儿童环境暴露、政策条件、社会机构和社区 特征-调查美国人一生中的健康、幸福感和死亡率 代代相传。

SUMMARY This project will complete a longitudinal data infrastructure including most of the U.S. population from 1940 through 2020. The linked infrastructure currently includes data from the censuses of 1940 and 2000-2020 and will soon include data from the censuses of 1960-1990. The current project will incorporate the 1950 Census and enhance the 1940 Census. These new data will provide the baseline observations for most of today’s oldest Americans. When complete, the entire 1940-2020 infrastructure will serve as a massive multi-purpose resource enabling a wide range of new discoveries and applications. We will undertake three key tasks to accomplish this goal: (1) link 1950 Census respondents into the broader infrastructure, (2) use new techniques to improve the coverage and accuracy of linkages currently available for the 1940 Census respondents, and (3) use a restricted Social Security Administration file to add new information on respondents’ exact date of birth, county of birth for those born in the U.S., and date of death for the deceased. With our addition of linked cases from 1940 and 1950, population health researchers will be able to use these data to analyze the life-course trajectories of hundreds of millions of Americans over the past century. Researchers will be able to incorporate information on early-life and ancestral experiences—such as parental economic status, childhood environmental exposures, policy conditions, social institutions, and neighborhood characteristics—into investigations of the health, well-being, and mortality of Americans over their lives and through generations.
