B: Transportation Economics and Policy

Japan has the fastest growth of aging ratio in the world. In addition to population decrease, the combination of the aging population with a diminishing number of children is becoming a critical issue. It is said that aging reduces the total railway demand. The study clarifies the number of immigrants and emigrants in each area along railway lines. The migrations between the railway lines having different characteristics of trends in age-structure are compared in the study. In the Tokyo Metropolitan Area, aspects of the population migrations are different in each area, and as a result, the difference in age structure causes a difference of railway passengers. In considering the details of population migration as presented in this study, additional strategic railway policy is necessary in the near future.
