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（由申请人提供）：该项目将创建一个全国性的 1930年美国100个公共使用微数据样本中的代表性一个 人口普查。样品的制备包括八个步骤：1）数据 输入了大约1 232 026人的资料， 2）编写词典， 数字代码的字母输入与现有系列兼容， 其他普查年度的微观数据; 3）通过 一致性检查，随机盲法验证约123，200例 以及与已出版的人口普查卷中的综合统计数据进行比较; 4） 编辑、清理和分配缺失、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 家庭组成、家庭内部关系、经济 6）编制文件，包括完整的 采样和数据处理方法的描述，程序历史 1930年人口普查，可比性问题的详细分析，以及用户的 7）评价和编辑数据字典和数据处理 1850年至1920年现有样本中使用的程序，以确保 与1930年新样本的一致性; 8）样本的整合， 综合公共使用微数据系列（IPUMS）。 新的样品代表了一个12年的努力，创造一个 综合人口普查数据库描述了美国人口从 从世纪中期到现在。它将完成IPUMS数据库， 具有全国代表性的高精度系列普查微观数据文件 从1850年到2000年。IPTJMS包括历史 从1850年到1920年，明尼苏达州为每一次幸存的人口普查创建了样本。 从1940年到2000年，IPUMS包含了 最初由人口普查局编制。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 样品完成的数据系列将包括大型、高精度的 1850年至2000年15个人口普查年度的兼容样本; 这些人口普查档案将共同构成一种前所未有的力量 研究长期的人口和经济变化。
