U.S. Participation in the Development of LIS, a Transnational Database: Luxembourg Income Study Database & Luxembourg Wealth Study Database, 2019 to 2023

该项目为跨国数据中心（前身为卢森堡收入研究）提供持续支持。LIS是一个独特的、跨国的数据基础设施，对于理解全球化世界中个人和家庭的社会和经济福祉至关重要。LIS的创建是为了通过提供家庭微观数据来促进初级研究，使理论和实证社会研究成为可能，为广泛的社会和经济政策和制度的分析提供信息。国家社会科学研究所保存着两个社会科学数据档案，目的是促成和促进关于高收入和中等收入国家社会经济成果的跨国研究。目前的项目将增加来自目前纳入的国家的新数据集以及来自其他国家的数据集。全球数千名研究人员使用卢森堡收入研究（LIS）和卢森堡财富研究（LWS）数据库来分析结果，包括贫困、收入不平等、就业状况、工资模式、性别不平等、家庭形成、移民、财富和债务积累。很大一部分基于lis的研究侧重于经济和社会政策影响这些结果的方式和程度。这些研究为美国和全球的收入和财富分配提供了政策输入。该项目协调（提供可比较的）来自多个国家的微观数据集，包括收入、财富、就业和人口统计数据。它提供了一种安全的方法：(1)允许调查人员访问具有隐私限制的数据；2)维护远程执行系统，使研究能够从现场以外的位置进行；3)促进微观数据在全球社会和经济福利比较研究中的应用。该项目在现场进行研究，并赞助和接待学者使用LIS数据。通过提供地理和经济上不同国家的数据集基础设施，该项目将继续扩大跨学科研究人员利用家庭微数据进行知识探索的基础。LIS数据集包括个人和家庭层面的收入、就业和人口统计变量。LIS数据库目前包括来自50个国家的微数据，包含300多个数据集，涵盖1968年至2016年；更新的LWS数据库包含来自15个国家的20个财富数据集，涵盖了1994年至2015年的时间。LIS和LWS的数据集加起来覆盖了大约86%的世界GDP和64%的世界人口。该项目编制和维持关于家庭不平等和贫困的标准化国家指标，这些指标可在国家统计局网站www.lisdatacenter.org上公开获取。关于基础调查、协调进程以及通过METIS（新的元数据系统）影响收入和财富水平和分配的具体国家机构，可以获得大量文件。该项目提供在线教学材料、用户支持、年度培训讲习班以及定期会议。LIS是研究人员交流思想、结果和方法的物理和虚拟场所；这些交流通过工作论文系列、访问学者计划、基于lis的会议、研讨会和公共项目以及博士前和博士后奖学金进行；通过年度研究奖来促进卓越。LIS为来自世界各地不同学科的数千名研究人员提供服务，包括经济学、社会学、政治学、政策研究和公共卫生。用户来自学术界、政府机构、非政府机构、超国家组织和新闻机构；三分之一的注册用户来自美国。LIS得到了卢森堡政府的大量资金支持。目前的项目将通过扩大合作、通过各种媒体进行交流和开发数据可视化，继续扩大其在学术界以外的影响。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This project provides continuing support for LIS, Cross-National Data Center (formerly Luxembourg Income Study). The LIS is a unique, cross-national, data infrastructure that is essential for understanding the social and economic wellbeing of persons and families in the globalized world. Created to foster primary research by providing access to household microdata, LIS enables both theoretical and empirical social research that informs analyses of a broad array of social and economic policies and institutions. LIS maintains two social science data archives for the purposes of enabling and fostering cross-national research on socio-economic outcomes in high- and middle-income countries. The current project will add new data sets from currently included countries as well as datasets from additional countries. Thousands of researchers worldwide use the Luxembourg Income Study (LIS) and Luxembourg Wealth Study (LWS) databases to analyze outcomes including poverty, income inequality, employment status, wage patterns, gender inequality, family formation, immigration, wealth and debt accumulation. A large share of LIS-based studies focus on the ways in which, and the extent to which, economic and social policies shape these outcomes. These studies provide policy input regarding income and wealth distributions in the United States and across the globe. This project harmonizes (renders comparable) micro-datasets from multiple countries that include data on income, wealth, employment and demography. It provides a secure method that: (1) allows investigators access to data with privacy restrictions; 2) maintains a remote-execution system to enable research conducted from off-site locations; and 3) promotes the use of microdata in comparative research on social and economic wellbeing on a global level. The project conducts research onsite, and sponsors and hosts scholars using the LIS data. By providing an infrastructure with datasets from geographically and economically diverse countries, the project will continue to broaden the basis for interdisciplinary researchers pursuing intellectual inquiry using household microdata. The LIS datasets include income, employment, and demographic variables at the person- and household-level. The LIS Database currently includes microdata from 50 countries and contains over 300 datasets spanning the years 1968 to 2016; the newer LWS Database contains 20 wealth datasets from 15 countries and covers the period 1994 to 2015. LIS and LWS datasets together cover approximately 86% of the world GDP and 64% of world population. The project prepares and maintains standardized national indicators on household inequality and poverty that are publicly available on the LIS website, www.lisdatacenter.org. Extensive documentation is available on the underlying surveys, the harmonization process, and the country-specific institutions that shape income and wealth levels and distributions through METIS, the new metadata system. The project provides online instructional materials, user support, and annual training workshops as well as periodic conferences. LIS is a physical and virtual venue for researchers to exchange ideas, results, and methods; these exchanges take place through the Working Paper Series, the Visiting Scholar Program, LIS-based conferences, workshops, and public programs, as well as pre- and post-doctoral scholarships; excellence is promoted through an annual research award. LIS serves thousands of researchers worldwide from various disciplines including economics, sociology, political science, policy studies, and public health. Users come from academia, government agencies, non-governmental agencies, supranational organizations and news agencies; one-third of registered users are from the United States. LIS is supported by substantial funding from the Luxembourg government. The current project will continue to broaden its impact beyond academia by expanding collaborations, communicating through various media, and developing data visualization.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
