Analysis of Chugoku area population structure

Since Meiji Era, several large-scale municipal mergers have been implemented in Japan. Similar movement is also promoted now, as a national policy, which called “Heisei no Daigappei.” The purpose of this policy is that the sufficient population is secured for local governments, in order to maintain the administration system required in the future. However, it is forecasted that the population of Japan is decreasing from now on, and it is not easy to hold that increased by the municipal mergers over the long term. Additionally, the efficiency of public is declining gradually among most new municipalities with the diffused structure as a necessity. Based on such recognition, the analysis of population structure caused by the municipal mergers in Chugoku Area and of the estimated population on some merged municipalities is shown in this paper.
