International Integrated Microdata Series

明尼苏达大学综合公共使用微数据系列(IPUMS)项目正在为科学研究、教育和政策制定创造基础设施。合作者创建了世界上最大的人口数据库，从1960年至2011年期间74个国家的238次人口普查和调查中提取了5.45亿人的信息。这项提议继续提供资金，以建立、丰富和自由传播规模和范围空前的微数据资源。下一个项目阶段将扩大数据库的覆盖范围，为子孙后代保留数据库，并将数据传播给世界各地的用户。该项目侧重于五项主要活动：(1)数据获取和长期保存；(2)数据清理和处理；(3)创建综合文件，指导用户了解普查和调查答复的意义及其在时间和空间上的可比性；(4)改进网上传播和分析系统，扩大教育和传播活动方案；(5)与各国统计机构共同开发具有披露风险的数据的安全传播系统，提供大量新的大数据。IPUMS是关键的科学基础设施。人口和经济资源的非同寻常的增长和重新分配正在重塑地球。为了应对快速的人口、经济和环境变化带来的挑战，研究人员必须能够充分和开放地获取最好的信息。几十年来全球范围内丰富详细的人口数据对于创建下一代社会科学和环境模型是不可或缺的。IPUMS的数据已经激发了超越国界和静态解释的新研究。数据库的扩展、改进和支持直接关系到美国国家科学基金会推动科学进步的中心任务。下一个项目阶段将利用NSF以前的投资，使IPUMS成为了解人类人口全面变革的原因和后果的更强大的资源。这一基础设施将使有关不断变化的人口的信息的质量、数量、可获得性和互操作性成倍增加，创造出在全球范围内了解人类社会的前所未有的跨国资源。通过传播大微数据，该项目将提高对人口老龄化、国际移民、气候变化以及政府计划对经济发展和福祉的影响等关键政策相关问题的科学理解。该项目将通过以下方式促进教学：(1)在线数据分析和教学教材共享；(2)举办培训讲习班和开发关于数据使用的在线教学模块；以及(3)雇用不同群体的研究生和本科生研究助理，包括代表人数不足的群体的成员，他们将在具有启发性的跨学科课程中发展宝贵的新技能

SES-1357452Steven RugglesRagui A. AssaadDeborah LevisonRobert E. McCaaAnne MeierUniversity of MinnesotaThe Integrated Public Use Microdata Series (IPUMS) project is creating fundamental infrastructure for scientific research, education, and policy-making. The collaborators have created the world's largest population database, with information describing 545 million persons drawn from 238 censuses and surveys of 74 countries between 1960 and 2011. This proposal continues funding to build, enrich, and freely disseminate a microdata resource of unprecedented scale and scope. This next project phase expands the coverage of the database, preserves it for future generations, and disseminates the data to users around the world. This project focuses on five major activities: (1) Data acquisition and long-run preservation; (2) Data cleaning and processing; (3) Creating comprehensive documentation to guide users on the meaning of census and survey responses and their comparability across time and space; (4) Improving the web-based dissemination and analysis system and conducting an expanded program of education and dissemination activities; and 5) Developing with national statistical agencies a secure dissemination system for data that pose disclosure risks, making a vast new trove of big data available. IPUMS is critical scientific infrastructure. The extraordinary growth and redistribution of population and economic resources are reshaping the planet. To meet the challenges created by rapid demographic, economic, and environmental change, researchers must have full and open access to the best possible information. Richly detailed population data spanning the globe over multiple decades are indispensable for creating the next generation of social science and environmental models. IPUMS data have already stimulated new research that transcends national boundaries and static interpretation. The expansion, improvement, and support of the database are directly relevant to the central mission of the NSF to promote the progress of science. The next project phase will leverage the NSF's previous investments and make IPUMS an even more powerful resource for understanding the causes and consequences of the sweeping transformations of the human population. This infrastructure will multiply the quality, quantity, accessibility, and interoperability of information about the changing population, creating a transnational resource of unprecedented power for understanding human society on a global scale. By disseminating big microdata, this project will enhance scientific understanding of critical policy-related issues such as population aging, international migration, climate change, and the effects of government programs on economic development and well-being. The project will promote teaching through: (1) online data analysis and sharing of curricular materials for teaching; (2) conducting training workshops and developing online instructional modules on data usage; and (3) employing a diverse group of graduate and undergraduate research assistants, including members of underrepresented groups, who will develop valuable new skills in a stimulating interdisciplinary en
