Exploring New Frontiers in Statistical Analysis using Micro Data Sets

在1980年代，欧洲和北美逐步提供了微观数据集的政府调查统计数据，供公众和学术界使用。然而，日本当局严格限制使用微观数据集。为了赶上这一国际趋势，统计理事会在1995年建议采用更灵活的方式使用微观数据集，以保护隐私和商业秘密。实现这一政策还存在许多问题和障碍。我们的项目是建立追求实际和理论的解决方案，为这一目标从院士和组织下的三个研究议程：1）统计和计算的理论方面，2）分析从政府调查获得的微观数据集的实验，3）使用微观数据集的法律的和制度方面。1）根据日本统计法，我们的项目申请了特别许可使用“指定统计”，由统计局A控制的重要统计调查 ...更多信息 CT，并使用这些数据进行数据分析。我们得到了五个部门和机构的十七个统计数据的许可。2）秘书处小组已经处理了这些微观数据集，作为订单制表的中心。1999年，本项目秘书处小组对整个项目进行了总结，并开始了新的数据处理程序，使用了20%的全国家庭收入和支出调查和就业状况调查的重新抽样数据。本课题由18名研究人员参与，开发了能够在不泄露数据的情况下进行信息交换的系统。此外，还对世界各国统计调查微观数据的公开现状进行了全面调查，并在此基础上，对各国统计调查微观数据的公开现状进行了分析。从法律的和实践的两个方面，我们的项目于1999年7月2-5日举行了研讨会，介绍我们在过去三年进行的个别研究计划的最终结果，这些研究计划是以最后，我们发表了“利用微观数据集探索统计分析新领域”项目的概要报告（日文版和英文版）。我们计划出版五套有关微观经济统计的讲座系列，首三册已于二零零零年二月出版。少

In the 1980s, government survey statistics in micro data sets were gradually made available for public and academic use in Europe and North America. However, Japanese authorities strictly restrict the use of micro data sets. In order to catch up such an international trend, Statistics Council made recommendation to adopt a more flexible way of using micro data sets protecting privacy and business secrets in 1995. There are many problems and obstacles to realize such a policy. Our project is to set up to pursue practical and theoretical solutions for this goal from the academicians and organized under the three research agenda : 1) theoretical aspects of statistics and computation, 2) experiments to analyze micro data sets obtained from governmental survey, 3) legal and institutional aspects of using micro data sets.1) Under the Japanese Statistics Law, our project applied for special permission to use "designated statistics", important statistical surveys controlled by the Statistics A … More ct, and conducted data analyses using these data. We got permissions of using seventeen statistics from five ministries and agencies.2) The secretariat group had processed these micro data sets as a center for order-made tabulation. In 1999, the secretariat group of our project summed up the whole project and started new data handling procedure by using 20%, re-sampled data from National Survey of Family Income and Expenditure and Employment Status Survey. 18 researchers were involved in this new project.Our project developed the system in which each participant of the project could exchange information without leaking private information from the data sets.In addition, we conducted the comprehensive survey on the current situation of the disclosure of the micro data sets of the statistical surveys in the various advanced countries, both from legal and practical aspects.Our project held the seminar on July 2-5, 1999, presenting the final results of the individual projects conducted in the past three years to demonstrate usefulness and safety of protecting privacy by our way of research against the statisticians of the government.As a conclusion, we published the summary report of our project on "Exploring New Frontiers in Statistical Analysis Using Micro Data Sets" (both in Japanese and English). For public use, we plan to publish the five lecture series on microeconomic statistics, and the first three volumes were published in February 2000. Less
