Abstract
This study aims at analyzing the population structure in terms of generation balance, and at classifying the municipalities in the Tokyo Metropolitan Area. For this purpose, a new index, the Generation Balance Index, was developed to describe the balance of the second generation to the first one, who first started to live in this area after the WWII. By comparing the generation balances of populations between 1980 and 2000, it is clarified that the Tokyo Metropolitan Area is not monotonous even in the suburbs. From the micro-scale analysis, it is clarified that the population is extremely out of balance in suburban detached housing areas, apartment housing developments, business and commercial districts near stations, and agricultural areas.
