Outline of Final Research Achievements

In this research, we developed a method of spatial factor analysis of income differentials and conducted research on its visualization. Specifically, as a preparatory stage for performing spatial factor analysis, research on estimating income distribution was advanced. Among others, we can find availability of lognormal distribution, we can conduct research such as constructing a model for factor analysis using lognormal distribution and extending to logarithmic normal distribution to mixture distribution. Regarding visualization, it was not possible to target spatial factors of income differentials, but taking the Hanshin-Awaji earthquake and analyzing the spatial factors of changes in participation behavior to earthquake insurance and visualizing it did it.
