Integrated Samples of European Censuses

描述(申请人提供)：自20世纪60年代以来的大量原始欧洲人口普查微观数据以机器可读的形式保存下来。然而，这些数据中的大多数仍然无法为研究人员所用。该提案寻求资金，以创建50多个西欧和东欧人口普查的统一和有文件记录的样本。这些数据将通过基于网络的数据传播系统提供给学术和教育研究。该项目利用了之前联邦政府在社会科学基础设施方面的投资。来自国家卫生研究院和国家科学基金会的拨款为欧洲数据系列奠定了基础，为许多初始成本提供了资金。这些项目为数据清理和采样程序、数据转换和传播软件以及数据和文件设计协议的开发提供了资金。我们已经为17个欧洲国家的60多次人口普查作出安排，以获得原始的微数据文件、内部文件和再分配协议，这些国家的人口总数为15亿。因此，欧洲新的公共使用的微数据样本将具有很高的成本效益。 为了充分利用过去的投资，并使研究人员能够广泛获得欧洲数据，必须执行下列任务：每次人口普查抽取新样本；重新格式化和清理样本；实行保密保护；将变量重新编码为现有的统一编码系统，并制定针对欧洲的新的编码设计；分配丢失和不一致的数据值；创建一套结构一致的变量；编制统一的英文文件；将所有文件转换为数据文件倡议元数据标准；改善和维护网上数据查阅系统。 这个新的数据库有超过7000万条记录，跨越40年，社会科学家将允许社会科学家在几十年的戏剧性变化中对欧洲各国进行比较。结合来自IPUMS其他项目的数据，这些信息将使跨时间和跨空间的创新比较研究成为可能。该数据系列将产生大量关于经济转型、人口转型和人口老龄化、国际移民和许多其他主题的新的科学和政策相关研究。

DESCRIPTION (provided by applicant): A vast quantity of raw European census microdata for the period since the 1960s survives in machine-readable form. Most of these data, however, remain inaccessible to researchers. This proposal seeks funding to create harmonized and documented samples of over 50 Western and Eastern European censuses. These data will be made available for scholarly and educational research through a web-based data dissemination system. This project leverages previous federal investments in social science infrastructure. Grants from the National Institutes of Health and the National Science Foundation have laid the groundwork for the European data series by funding many of the initial costs. Those projects have underwritten the development of data cleaning and sampling procedures, data conversion and dissemination software, and design protocols for data and documentation. We have already made arrangements to obtain raw microdata files, internal documentation, and redistribution agreements for over 60 censuses of 17 European countries with populations totaling one-half billion people. As a result, the new public-use microdata samples for Europe will be highly cost-effective. The following tasks must be carried out to capitalize on these past investments and make the European data widely available to researchers: draw new samples of each census; reformat and clean the samples; impose confidentiality protections; recode variables into existing harmonized coding systems and develop new coding designs optimized for Europe; allocate missing and inconsistent data values; create a set of consistent constructed variables; develop harmonized English-language documentation; convert all documentation to the Data Documentation Initiative metadata standard; and improve and maintain the web-based data access system. With over 70 million records spanning a forty-year period, the new database will allow social scientists to make comparisons across European nations during decades of dramatic change. Coupled with data from other IPUMS projects, this information will allow innovative comparative research across time and space. The data series will result in a substantial body of new scientific and policy-relevant research on economic transformation, demographic transition and population aging, international migration, and many other topics.
