Integrated Samples of Latin American Censuses, 1960-2003

描述(申请人提供)：自1960年以来拉丁美洲的大量原始人口普查微观数据档案以机器可读的形式保存下来。然而，研究人员仍然无法获取这些数据中的大部分。该提案寻求资金，以创建约55个拉丁美洲和加勒比人口普查的统一和有文件记录的样本。这些微观数据和元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赠款为拉丁美洲的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。几乎每个拉丁美洲国家的人口普查的原始微观数据文件、内部文件和再分配协议都已获得。因此，为拉丁美洲开发新的公共使用样品的成本将不到以前项目的一半。为了充分利用过去的投资，并使研究人员能够广泛查阅拉丁美洲的数据，必须开展下列工作：清理原始数据档案；从100%的内部普查档案中抽取新的样本；实行保密保护；将变量重新编码为现有的统一编码系统，并制定针对拉丁美洲的新的编码设计；分配丢失的和不一致的数据值；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举措元数据标准；改善和维护网上数据查询系统。这个新的数据库有超过1亿条记录，涵盖了40年的时间段，社会科学家将允许社会科学家在40年的戏剧性变化中对拉丁美洲国家进行比较。该数据系列将产生大量关于经济发展、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与政策相关的健康相关研究。

DESCRIPTION (provided by applicant): A vast archive of raw census micro data covering Latin America in the period since 1960 survives in machine readable form. The bulk of these data, however, remains inaccessible to researchers. This proposal seeks funding to create harmonized and documented samples of approximately fifty-five Latin American and Caribbean censuses. These micro data and metadata 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 Latin American data series by funding many of the initial costs. These projects have underwritten the development of data cleaning and sampling procedures, data conversion and dissemination software, and design protocols for data and documentation. Raw micro data files, internal documentation, and redistribution agreements for the censuses of virtually every Latin American country have been obtained. As a result, the costs of developing new public-use samples for Latin America will be less than half as great as for previous projects. The following tasks must be carried out to capitalize on these past investments and make the Latin American data widely available to researchers: clean raw data files; draw new samples from 100% internal census files; impose confidentiality protections; recode variables into existing harmonized coding systems and develop new coding designs optimized for Latin America; 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 100 million records covering a forty-year period, the new database will allow social scientists to make comparisons across Latin American nations during four decades of dramatic change. The data series will result in a substantial body of new scientific and policy-relevant health-related research on economic development, demographic transition and population aging, international migration, and many other topics.
