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

本研究考察了经济衰退、（地区）人口减少和老龄化对福岛县沿海地区（磐城市等）和茨城市北部各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，但考虑到它们的影响，研究仍在继续。研究发现，在灾难发生前，农村人口下降和老龄化显著，而经济衰退对中部和工业化地区的影响更大。灾难发生后，沿海和中部地区以及受核事故影响的地区出现了人口下降（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.
