One of the problems in many local governments in Japan is population decline. This is no exception even in ordinance-designated cities, and the population will decline significantly in some cities. The population of Yokohama City differs from north to south areas in terms of its population growth. Furthermore, the characteristics of each area also differ among directions (north, south, east, and west). Therefore, if Yokohama City considers measures for population decline, it is at least important to understand the characteristics of demographics at the ward level. In this study, we clustered the characteristics of changes of populations, social populations, and natural populations based on the time trend in the wards of Yokohama City. Then, the results of the classifications were further evaluated. Finally, the characteristics of each ward were clarified, and we furthermore considered future population changes based on the results.
