Microdata for Analysis of Early Life Conditions, Health, and Population

描述(由申请人提供)：这是一个由三部分组成的项目的第一部分，该项目旨在创建一个涵盖1940年美国全部人口的大规模微数据资源。该数据库将提供有关教育程度、移民状况、劳动力状况、工资和薪金收入、每周工作时间和去年工作周的最早信息。因此，它将为社会和经济变化的批判性分析提供基线。研究人员将能够将最近的健康调查、行政记录和国家死亡指数与1940年的数据库联系起来，从而能够研究早期生活条件--包括社会经济地位、父母教育和家庭结构--对后来健康和死亡率的影响。该数据库将涵盖所有人口的全部地理细节，提供有关儿童社区特征、劳动力市场条件和环境条件的背景信息。新的数据库将成为国家统计基础设施的永久性和实质性补充，并将对社会科学和行为科学的研究产生深远影响。该项目涉及(1)按键转录78亿次描述1940年美国所有个人、家庭、家庭和群体的人口和经济特征的数据；(2)通过随机盲目核实和与公布的人口普查报告进行比较，评估数据质量；(3)开发数据词典，将大约260万份不同的不限成员名额的人口普查答复转换成与以前和以后的人口普查数据兼容的数字分类；(4)数据清理，包括对不一致和缺失的数据值进行编辑和推算；(5)编制文件，包括对数据处理方法的详细说明、对可比性问题的详细分析和全面的机器可处理的元数据；(6)将数据库纳入综合公共使用微观数据系列(IPUMS)数据访问系统，免费向科学界传播；(7)实施安全的数据保护和保存政策。拟议的工作将由一支高技能的研究人员团队进行，他们在大规模数据创建、集成和传播方面拥有无与伦比的专业知识和经验。该项目是明尼苏达州人口中心与全国最大的家谱数据生产商和国家档案和记录管理局合作的项目。这种合作使稀缺资源能够以极具成本效益的方式用于人口和卫生研究的共享基础设施。

DESCRIPTION (provided by applicant): This is the first component of a three-part project to create a massive microdata resource comprising the entire population of the United States in 1940. The database will provide the earliest information available on educational attainment, migration status, labor force status, and wage and salary income, hours worked per week, and weeks worked last year. Accordingly, it will provide the baseline for critical analyses of social and economic change. Researchers will be able to link recent health surveys, administrative records, and the national death index to the 1940 database, allowing study of the impact of early life conditions-including socioeconomic status, parental education, and family structure-on later health and mortality. The database will cover the entire population with full geographic detail, providing contextual information on childhood neighborhood characteristics, labor-market conditions, and environmental conditions. The new database will make a permanent and substantial addition to the nation's statistical infrastructure, and will have far-reaching implications for research across the social and behavioral sciences. The project involves (1) transcription of 7.8 billion keystrokes of data describing the demographic and economic characteristics of all individuals, families, households, and group quarters present in the United States in 1940; (2) evaluation of data quality through random blind verification and comparison with published census returns; (3) development of data dictionaries to convert approximately 2.6 million different open-ended census responses into numeric classifications compatible with previous and subsequent census data; (4) data cleaning, including editing and imputation of inconsistent and missing data values; (5) development of documentation, including full descriptions of data processing methods, detailed analysis of comparability issues, and comprehensive machine-processable metadata; (6) incorporation of the database into the Integrated Public Use Microdata Series (IPUMS) data access system for free dissemination to the scientific community; and (7) implementation of secure data protection and preservation policies. The proposed work will be carried out by a team of highly-skilled researchers with unparalleled expertise and experience in large-scale data creation, integration, and dissemination. The project is a collaboration of the Minnesota Population Center with the nation's largest producers of genealogical data and the National Archives and Records Administration. This collaboration allows a highly cost-effective use of scarce resources for shared infrastructure for population and health research.
