Outline of Final Research Achievements

I create pseudo-micro data based on the synthetic data method in accordance with the Japanese system, and examine methods for providing these data, using various data to create pseudo-micro data, and examine its properties.
Based on these preparations, permission was obtained to use official statistical microdata. Then, I created pseudo-micro data using the official statistical micro-data and analyzed its properties. I also examined methods for implementing education using this data. The results of these studies were published in academic journals. These research results were reported at conferences, symposiums, research meetings, etc.
A workshop (sponsored by the Official Statistical Microdata Research Consortium) was held using the created pseudo microdata. Then, we considered how to utilize the data in education, and sorted out future issues.

Academic Significance and Societal Importance of the Research Achievements

擬似的なミクロデータを作成す際に諸外国で標準的に用いられている合成データ（Synthetic Data）の方法を、我が国の公的統計データに関する法令・制度に沿った形で適用し、実際の公的統計ミクロデータを基に、擬似的なミクロデータを作成・提供するための方法論を提案するとともに、その手順や課題について整理することができた。
また、ワークショップの場における、擬似的なミクロデータを用いた教育・研究の実践を行うことで、こうした擬似的なミクロデータを用いる際の方法や課題について検討し、整理することができた。
