General SummaryThe Standardized World Income Inequality Database (SWIID) aims to provide data on income inequality for the broadest possible sample of countries and years that are made as comparable as possible. Income inequality is an enduring focus of inquiry in the social sciences that has attracted renewed attention from policymakers and the public. Economists, political scientists, sociologists, and other social scientists have long sought to explain why incomes are relatively equal in some countries and times and much larger disparities between rich and poor are found in others. The effects of income inequality on other forms of social inequality, such as health disparities, and on other phenomena ranging from political violence to economic growth to democratic transitions are similarly vital questions. The reliability of the results of these investigations and any policy interventions they suggest, depend crucially on the quality of the income-inequality data they employ; the SWIID is therefore a data infrastructure project that is central to the promotion of scientific progress on these topics.Technical SummaryThe SWIID surpasses other inequality datasets by directly addressing their tradeoff between coverage of countries over time and the comparability of the data they supply. It does so by using model-based multiple-imputation methods on data drawn from regional collections, national statistical offices, and academic studies to generate estimates for the missing country-years in the high-quality but sparse Luxembourg Income Study dataset. It currently provides comparable estimates of market- and net-income inequality for 174 countries for as many years as possible from 1960 to the present. The proposed research comprises four principal activities to improve the SWIID project: (1) acquiring and cleaning data to expand its coverage, (2) assessing and improving the multiple-imputation techniques used to ensure its estimates are comparable, (3) expanding documentation to help researchers use income-inequality data in ways appropriate to their research questions, and (4) improving the web-based system for disseminating the SWIID to researchers, educators, and policymakers worldwide. The SWIID has been used by thousands of researchers around the world working in academia, governments, non-governmental organizations, international organizations, and news agencies. Expanded and refined versions of the SWIID will make improved knowledge on income inequality even more accessible to policymakers and the public as well as to researchers and educators.

标准化世界收入不平等数据库（SWIID）旨在提供尽可能广泛的国家和年份的收入不平等数据，这些数据尽可能具有可比性。 收入不平等是社会科学研究的一个持久焦点，引起了政策制定者和公众的重新关注。 长期以来，经济学家、政治学家、社会学家和其他社会科学家一直试图解释为什么在某些国家和时代，收入相对平等，而在另一些国家和时代，贫富差距却要大得多。 收入不平等对其他形式的社会不平等，如健康差距，以及对从政治暴力到经济增长到民主过渡等其他现象的影响，也是同样重要的问题。 这些调查结果的可靠性以及它们所建议的任何政策干预，关键取决于它们所使用的收入不平等数据的质量;因此，SWIID是一个数据基础设施项目，对促进这些主题的科学进步至关重要。技术摘要SWIID超越了其他不平等数据集，直接解决了国家随时间的覆盖范围与数据可比性之间的权衡问题。他们提供的数据。 为此，它使用基于模型的多重插补方法，对从区域收集、国家统计局和学术研究中获得的数据进行插补，以生成高质量但稀疏的卢森堡收入研究数据集中缺失的国家年的估计数。它目前提供了174个国家从1960年至今尽可能多年的市场和净收入不平等的可比估计。拟议的研究包括四项主要活动，以改善SWIID项目：（1）获取和清理数据以扩大其覆盖范围，（2）评估和改进用于确保其估计具有可比性的多重插补技术，（3）扩大文献，以帮助研究人员以适合其研究问题的方式使用收入不平等数据，以及（4）改进基于网络的系统，以便向全世界的研究人员、教育工作者和决策者传播SWIID。 SWIID已被世界各地的学术界、政府、非政府组织、国际组织和新闻机构的数千名研究人员使用。 扩大和改进后的SWIID将使决策者和公众以及研究人员和教育工作者更容易获得关于收入不平等的更好的知识。
