Spatial Changes in the Population and Income of Small and Medium-Sized Cities with Aging, Decreasing Birthrate, and Recession: The Case of Joban Region

本研究调查了经济衰退、（地区）人口减少和老龄化对福岛沿海地区（岩城市等）和茨木北方地区各地区人口和收入的影响。虽然在项目期间发生了2011年东北地震和核事故，但考虑到其影响，研究仍在继续。研究发现，在灾难发生之前，农村地区的人口减少和老龄化已经很明显，而经济衰退的影响在中部和工业化地区更大。灾后，沿海和中部地区以及受核事故影响的地区的人口减少（主要是由于移民）。

This study investigates the effects of recession, (regional) population decrease and aging on the population and income of each district of the coastal region of Fukushima (Iwaki City and others) and the northern region of Ibaraki. Although 2011 Tohoku earthquake and a nuclear accident occurred during the period of the project, the research was continued taking into account their effects. The study finds that, before the disaster, population decline and aging in rural areas had been significant while the effect of the recession had been larger in the central and industrialized areas. After the disaster, decline in population (mainly due to emigrations) has been observed in the coastal and central areas and the areas that have been affected by the nuclear accident.
