Integrating, Preserving, and Disseminating Linked CPS Data

 描述(由申请人提供)：该提案寻求持续资金，以增强和扩大IPUMS-CPS，具有集成的数据、传播软件和关联元数据，极大地简化了对当前人口调查(CPS)数据的纵向分析，消除了多余的研究工作，并打开了新的发现机会。IPUMS-CPS通过创新的用户界面自由传播数据，该界面为搜索、发现、研究设计和数据访问提供了强大的工具。拟议的项目将使研究人员能够灵活地获取60年来CPS调查的综合和有据可查的纵向数据，包括1976年至2020年的所有基本月度调查、1962年至2020年的年度社会和经济补编(ASEC)文件，以及1967年至2020年的所有其他幸存的专题补编。IPUMS-CPS通过以下方式为科学事业服务：减少浪费的重复劳动(例如，链接文件和协调变量)，消除常见的技术错误(例如，方差估计)，使研究结果更容易复制，并鼓励和促进许多研究领域复杂和强大的新的纵向分析。为了实现这些目标，我们提出了六项具体任务：(1)清理、核实和消除20世纪60年代、70年代和80年代恢复的CPS文件，为披露审查做准备，并将它们整合到公共使用的IPUMS集合中；(2)通过整合2015至2020年间发布的近78个新文件的数据来扩展数据库，包括所有CPS月度数据和补充数据，以及我们与人口普查局合作恢复的数据；(3)与人口普查局合作，将IPUMS-CPS链接到受限的CPS文件的关键字，用于人口普查局的研究数据中心网络；(4)开发更多新的关键字，以便随着时间的推移将气候变化问题的观察结果联系起来，系统地比较不同方法产生的联系，并向用户提供关于这些关键字和它们之间差异的文件；(5)创建新的数据获取和数据处理工具；(6)为用户提供支持并在各次会议上开展外联活动，扩大在线数据分析能力，主办深入培训讲习班，并实施一项新的微数据和元数据长期保存计划。拟议的工作将由一组高技能的研究人员进行，他们在数据集成、记录链接和CPS方面拥有无与伦比的专业知识。合作者包括来自明尼苏达州人口中心、美国人口普查局、劳工统计局、Unicon研究公司和NORC的主要研究人员。该项目将采用尖端软件创新、广泛的可用性测试和建立的元数据标准。

 DESCRIPTION (provided by applicant): This proposal seeks continuation funding to enhance and expand IPUMS-CPS, featuring integrated data, dissemination software, and associated metadata that dramatically simplifies longitudinal analyses of Current Population Survey (CPS) data, eliminating redundant research effort and opening new opportunities for discovery. IPUMS-CPS freely disseminates data through an innovative user interface that provides powerful tools for search, discovery, research design, and data access. The proposed project will provide researchers with flexible access to integrated and well-documented longitudinal data across six decades of CPS surveys, including all basic monthly surveys from 1976 through 2020, Annual Social and Economic Supplement (ASEC) files from 1962 through 2020, and all other surviving topical supplements from 1967 through 2020. IPUMS- CPS serves the scientific enterprise by reducing wasteful duplication of effort (e.g., in linking files and harmonizing variables), eliminating common technical errors (e.g., in variance estimation), making findings easier to replicate, and encouraging and facilitating sophisticated and powerful new longitudinal analyses in many research domains. To accomplish these goals, we propose six specific tasks: (1) Clean, verify, and de-identify recovered CPS files from the 1960s, 1970s, and 1980s in preparation for disclosure review and integrate them into the public- use IPUMS collection; (2) Expand the database by integrating data from nearly 78 new files that will be released between 2015 and 2020, including all CPS monthly and supplement data as well as data we recover in collaboration with the Census Bureau; (3) Collaborate with the Census Bureau to add IPUMS-CPS linking keys to restricted CPS files for use in the Census Bureau's Research Data Center network; (4) Develop additional new keys for linking CPS observations over time, systematically compare the linkages resulting from different approaches, and provide users with documentation about the keys and differences between them; (5) Create new tools for data access and data processing; (6) Provide user support and perform outreach at conferences, expand online data analysis capabilities, host in-depth training workshops, and implement a new plan for long-run preservation of the microdata and metadata. The proposed work will be carried out by a team of highly-skilled researchers with unparalleled expertise in data integration, record linkage, and the CPS. Collaborators include leading researchers from the Minnesota Population Center, the U.S. Census Bureau, the Bureau of Labor Statistics, the Unicon Research Corporation, and NORC. The project will employ cutting-edge software innovations, extensive usability testing, and established metadata standards.
