A Multigenerational Longitudinal Panel for Aging Research

摘要/摘要 该项目将建造一个规模空前的多代纵向面板(IPUMS-MLP)和 作用域。使用尖端的自动记录链接技术，借鉴美国人口普查的完整统计 根据IPUMS提供的1850年至1940年期间的数据，该项目将构建数百万个人的生活史 并在几代人的时间里追踪数百万个家庭。这一基础设施将提供最全面的 世界上任何地方都可以看到生命历程动态的长期变化，并将改变我们的 对人口老龄化过程的理解。这项工作需要重大的创新和新的技术 基础设施，以适应庞大的数据库规模。 这些数据将使研究人员能够直接观察衰老过程和生命过程转变的变化 在工业化、城市化、移民正在改变美国社会的时期， 人口结构转型和经济崩溃。调查人员将能够随着时间的推移跟踪个人 评估早期生活状况对以后结果的影响，追踪成年和老年的生命过程转变 年龄，并观察多代人的家庭变化。IPUMS-MLP将通过以下方式丰富现有的老龄化调查 提供调查受访者多代祖先的数据；同样，它将丰富现有的 历史数据库，使它们能够与跨越多代的后代建立联系。利用 数十亿美元的联邦投资，用于人口普查数据和来自各种行政部门的交易记录 消息来源，该项目是一种利用稀缺资源开发共享基础设施的高成本效益的项目 关于健康和老龄化的研究、教育和政策制定。

Summary/Abstract This project will construct a Multigenerational Longitudinal Panel (IPUMS-MLP) of unprecedented scale and scope. Using cutting-edge automatic record linkage technology and drawing on complete count U.S. census data available from IPUMS for the period 1850 to 1940, the project will construct millions of individual life histories and trace millions of families over multiple generations. This infrastructure will provide the most comprehensive view of long-run changes in life-course dynamics available for any place in the world and will transform our understanding of processes of population aging. The work will require significant innovation and new technical infrastructure to accommodate the massive scale of the database. These data will allow investigators to directly observe changes in aging processes and life-course transitions during the period in which U.S. society was being transformed by industrialization, urbanization, immigration, demographic transition, and economic collapse. Investigators will be able to follow individuals over time to evaluate the impact of early-life conditions on later outcomes, trace life-course transitions into adulthood and old age, and observe family change over multiple generations. IPUMS-MLP will enrich existing aging surveys by providing data on multiple generations of forebears of survey respondents; likewise, it will enrich existing historical databases by enabling them to connect with descendants across multiple generations. Leveraging billions of dollars of federal investments in census data and transactional records from a variety of administrative sources, this project is a highly cost-effective use of scarce resources to develop shared infrastructure for research, education, and policy-making on health and aging.
