Abstract
This article aims at estimating the spatial distributions of earnings at the small area level in Kyoto City, Japan by using a spatial microsimulation. A spatial microsimulation is a method to create a synthetic micro dataset at the small area level by combining different datasets. In this article, we created a synthetic micro dataset from the Person-Trip Survey in the manner that it agreed with census tables. Earnings of individuals were then estimated based on their attributes and added to it. Finally, the synthetic micro dataset was re-tabulated to map earning indices for understanding various aspects of geographical inequalities.
