DESCRIPTION (provided by applicant): This project will create a nationally representative one-in-100 public use microdata sample of the 1930 United States Census of Population. Preparation of the sample includes eight steps: 1) Data entry of information on approximately 1,232,026 individuals from the original enumerators' manuscripts; 2) Development of dictionaries to translate each alphabetic entry into numeric codes compatible with the existing series of microdata for other census years; 3) Evaluation of sample quality through consistency checks, random blind verification of approximately 123,200 cases and comparison with aggregate statistics in the published census volumes; 4) Editing, cleaning and allocation of missing, illegible and inconsistent data through logical rules and imputation procedures; 5) Construction of new variables on household composition, relationships within families, economic status and ethnicity; 6) Development of documentation, including full descriptions of the sampling and data processing methods, a procedural history of the 1930 census, a detailed analysis of comparability issues, and a user's guide; 7) Evaluation and editing of data dictionaries and data processing procedures used in the existing samples covering 1850 to 1920 to ensure consistency with the new 1930 sample; 8) Integration of the sample and documentation into the Integrated Public Use Microdata Series (IPUMS). The new sample represents the capstone of a twelve-year effort to create an integrated census database describing the American population from the mid-nineteenth century to the present. It will complete the IPUMS database, a nationally representative high-precision series of census microdata files spanning the period from 1850 through 2000. The IPTJMS includes historical samples created at Minnesota for every surviving census from 1850 through 1920. For the period from 1940 through 2000, the IPUMS incorporates samples that were originally prepared by the Census Bureau. The 1930 census is the missing link that will close the gap between the Minnesota samples and the Census Bureau samples. The completed data series will include large, high-precision compatible samples for fifteen census years between 1850 and 2000; taken together, these census files will constitute a resource of unprecedented power for the study of long-run demographic and economic change.

描述(由申请者提供)：该项目将创建一个全国性的 具有代表性的1930年美国公众使用微数据样本 人口普查。样品的制备包括八个步骤：1)数据 从原件中录入约1,232,026人的信息 枚举员手稿；2)开发词典以翻译每个手稿 按字母顺序输入与现有系列兼容的数字代码 其他人口普查年的微观数据；3)通过以下方式评价样本质量 一致性检查，随机盲检约123,200例 并与已出版的人口普查卷中的总统计数字进行比较；4) 编辑、清理和分配丢失、难以辨认和不一致的数据 通过逻辑规则和归责程序；5)构建新的 关于家庭构成、家庭关系、经济状况的变量 身份和族裔；6)编制文件，包括完整的 抽样和数据处理方法的说明，程序历史 1930年的人口普查，对可比性问题的详细分析，以及用户的 指南；7)数据词典和数据处理的评价和编辑 在1850至1920年的现有样本中使用的程序，以确保 与新的1930年样品的一致性；8)样品和 将文件纳入综合公共使用微观数据系列(IPUMS)。 新的样本代表了12年来创造一个 描述美国人口的综合人口普查数据库 从十九世纪中叶到现在。它将完成IPUMS数据库，一个 具有全国代表性的高精度系列人口普查微数据文件 时间跨度从1850年到2000年。IPTJMS包括历史 从1850年到1920年，在明尼苏达州为每一次幸存的人口普查制作的样本。 在1940年至2000年期间，IPUMS纳入了以下样本 最初是由人口普查局准备的。1930年的人口普查是缺失的一环 这将缩小明尼苏达州样本和人口普查局之间的差距 样本。完成的数据系列将包括大的、高精度的 1850年至2000年间15个人口普查年的相容样本；采集 总而言之，这些人口普查文件将构成一种前所未有的力量 用于研究长期的人口和经济变化。
