项目摘要 IPUMS是一个由九个集成数据库组成的系列，其中包含最大和使用最频繁的数据 人口动态和健康研究的资源。这一相互竞争的延续提议有两个主要方面 目标。首先，该项目将为扩大、改进和维护IPUMS-USA提供主要支持， 它由十年一次的人口普查和美国社区调查的微观数据组成。第二，项目 将在9个IPUMS数据库之间提供中央协调，利用协同效应并消除 多余的工作。在过去的五年中，使用IPUMS的研究人员数量出现了爆炸性增长 数据库，他们请求的数据量，以及他们出版的影响很大的出版物的数量。在 然而，与此同时，研究人员对扩展、改进和支持的需求前所未有 基础设施的建设。为满足这一需求，该项目将开展四项主要活动： 1.数据库扩容。未来五年，IPUMS-USA的数据量将急剧增长 纳入提供20亿条个人一级信息记录的统一数据集。 2.数据和元数据改进。提高IPUMS-USA数据和元数据的质量是当务之急。 我们计划(1)家庭形式、贫困和医疗保险方面的新变量；(2)新的地理措施；(3) 简化了分类变量。 3.完善数据基础设施。该项目将实施(1)多处理器数据访问软件， 将提高数据访问速度并适应快速增长的大规模数据需求； 面向用户的API，支持外部应用程序的直接访问；(3)在线数据的可持续性规划 分析；(4)新的数据访问功能。 4.综合平台管理系统的协调。该项目将同步进行技术开发、用户支持和外联， 以及跨九个IPUMS数据库的保护和可持续性规划的长期规划，以避免 重复工作，增加影响，降低IPUMS数据基础设施的成本。 IPUMS通过最大限度地减少多余的工作来降低人口和卫生研究社区的成本， 简化数据访问，增加研究的可复制性，提高数据可靠性。是否可以使用 大规模集成的微数据为细粒度的上下文数据打开了非凡的新机遇 对人口动态和健康的分析，导致了跨不同范围的变革性研究 主题和学科。

Project Summary IPUMS is a family of nine integrated databases that comprise the largest and most intensively-used data resource for research on population dynamics and health. This competing continuation proposal has two main goals. First, the project will provide the primary support for expanding, improving, and maintaining IPUMS-USA, which consists of microdata from decennial censuses and American Community Surveys. Second, the project will provide central coordination across the nine IPUMS databases, exploiting synergies and eliminating redundant work. Over the past five years, IPUMS has seen explosive growth in the number of researchers using the database, the amount of data they request, and the number of high-impact publications they produce. At the same time, however, there is unprecedented demand from researchers for expansion, improvement, and support of the infrastructure. This project will undertake four major activities to meet this demand: 1. Database expansion. The quantity of data in IPUMS-USA will expand dramatically over the coming five years to include harmonized datasets providing two billion records of individual-level information. 2. Data and metadata improvement. Improving the quality of IPUMS-USA data and metadata is a top priority. We plan (1) new variables on family forms, poverty, and health insurance; (2) new geographic measures; (3) streamlined categorical variables. 3. Data infrastructure improvement. The project will implement (1) multi-processor data access software that will improve data access speed and accommodate the rapidly growing demand for large-scale data; (2) a user-facing API to enable direct access by external applications; (3) sustainability planning for online data analysis; (4) new data access capabilities. 4. IPUMS coordination. The project will synchronize of technological development, user support and outreach, and long-run planning for preservation and sustainability planning across the nine IPUMS databases to avoid duplication of effort, increase the impact, and reduce the cost of IPUMS data infrastructure. IPUMS reduces costs for the population and health research community by minimizing redundant effort, simplifying data access, increasing the replicability of studies, and improving data reliability. The availability of large-scale integrated microdata has opened extraordinary new opportunities for fine-grained contextual analyses of population dynamics and health, resulting in transformational research across a diverse range of topics and disciplines.
