Integrated Samples of Latin American Censuses

描述（由申请人提供）：自1960年以来，涵盖拉丁美洲的原始人口普查微观数据的大量档案以机器可读的形式保存下来。在过去的五年里，这个项目首次将这些数据的很大一部分提供给了研究人员。这项申请寻求资金，以完成一个综合数据库的工作，其中包括大约100个拉丁美洲和加勒比人口普查的样本。这些微数据和随附文件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对社会科学基础设施的投资。美国国立卫生研究院和美国国家科学基金会的赠款资助了许多初始费用，为拉丁美洲数据系列奠定了基础。这些项目资助发展数据清理和抽样程序、元数据系统、数据转换和传播软件以及数据和文件设计协议。已经获得了几乎所有拉丁美洲国家的原始微数据文件、内部文件和人口普查重新分配协议。因此，这个项目具有很高的成本效益。该项目有四个主要目标：1)大幅扩大数据库，使所包括的国家数量增加一倍，并增加每个国家2010年的人口普查，使数据库的总规模增加约92%；2)改进变量编码，特别是地理变量的编码；3)创建和传播新的数据产品，包括地理边界文件、跨时空一致的汇总摘要文件、包含完整地理代码的完整枚举的受限访问微数据；4)实施新的基础设施，以改善数据访问和用户支持，并降低长期维护成本。新数据库包含1.5亿条公共访问数据记录和超过5亿条限制访问数据记录，跨越50年的时间，将使社会科学家能够在变革时期对拉丁美洲国家进行比较。它将成为了解在过去半个世纪中重塑西半球的非凡社会和经济变革的原因和后果的有力资源，包括有关经济发展、人口转型和人口老龄化以及国际移民的新科学和与政策相关的健康相关研究。拟议的数据库与美国国立卫生研究院作为国家医学和行为研究的管理者的中心使命直接相关；这种基础设施将促进关于人口动态性质的基本知识，并将激发新的与健康有关的研究。该数据系列将产生大量关于经济发展、人口转型、人口老龄化和国际移徙的与健康有关的新科学和政策研究。通过开放对大量微观数据的访问，该项目将使社会科学和卫生研究人员能够解决有关在过去半个世纪中重塑西半球的非凡社会和经济变革的影响的基本问题。

DESCRIPTION (provided by applicant): A vast archive of raw census microdata covering Latin America in the period since 1960 survives in machine- readable form. Over the past five years, this project has made a substantial portion of these data available to researchers for the first time. This application seeks funding to complete work on an integrated database including samples of approximately 100 Latin American and Caribbean censuses. These microdata and accompanying documentation 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 laid the groundwork for the Latin American data series by funding many of the initial costs. Those projects underwrote the development of data cleaning and sampling procedures, metadata systems, data conversion and dissemination software, and design protocols for data and documentation. Raw microdata files, internal documentation, and redistribution agreements for the censuses of virtually every Latin American country have been obtained. As a result, this project is highly cost- effective. The project has four major goals: 1) expand the database dramatically, doubling the number of countries included and adding the 2010 round of censuses for each country, increasing the total size of the database by some 92 percent; 2) improve variable coding, especially for geographic variables; 3) create and disseminate new data products, including geographic boundary files, aggregate summary files that are consistent across time and space, and restricted access microdata that include complete enumerations with full geographic codes; and, 4) implement new infrastructure to improve data access and user support and reduce the cost of long- term maintenance. With 150 million records of public-access data and over a half-billion records of restricted-access data spanning a fifty-year period, the new database will allow social scientists to make comparisons across Latin American nations during a period of transformative change. It will be a powerful resource for understanding the causes and consequences of the extraordinary social and economic transformations that have reshaped the hemisphere during the past half century, including new scientific and policy-relevant health-related research on economic development, demographic transition and population aging, and international migration. PUBLIC HEALTH RELEVANCE The proposed database is directly relevant to the central mission of the National Institutes of Health as the steward of medical and behavioral research for the nation; this infrastructure will advance fundamental knowledge about the nature of human population dynamics and will spark new health-related research. The data series will result in a substantial body of new scientific and policy-relevant health-related research on economic development, demographic transition, population aging, and international migration. By opening access to a vast collection of microdata, the project will allow social science and health researchers to address fundamental questions about the impact of the extraordinary social and economic transformations that have reshaped the hemisphere during the past half century.
