Distribution System for Japanese Synthetic Population Data with Protection Level

Abstract

In this paper, we introduce a distribution system of synthesized data of Japanese population using Interdisciplinary Large-scale Information Infrastructures in Japan. Synthesized population is synthesized based on the statistics of census that are publicly released. Therefore, the synthesized data have no privacy data. However, since it is easy to estimate the compositions of households, working status in a certain area from the synthesized population, we distribute the synthesized data only for public or academic purposes. In the academic purposes, it is important to encourage young scholars to use a large-scale data of households, we define security levels for the attributes in the synthesized populations. According to the security levels, we distribute the data with proper attributes to applicants. We encourage researchers to use the synthetic populations to be familiar to large-scale data processing.
