This paper aims to clarify the change of density of urban facilities in central Tokyo (ward area), and to analyze the change of density of urban facilities and its dependence on age structure of small district. We focus on age structure that have an influence on change of density of urban facility, and clarified its relationship. Day nursery, kindergarten, elementary school, junior high school, and hospital are taken up as urban facilities in this paper. We find out that the change in the density of each urban facility is partially explained by that in population density by using kernel density functions with appropriate radius.
