This study aims at analyzing the interrelationship between district characteristics and generational changes at micro-level by applying Generation Balance Index (GBI) to 1950's, 1960's and 1970's cohorts as offspring generations of the first generation who settled in the suburbs during the high economic growth period. The "Generation Balance Index (GBI)" is an index which shows the relationship between the parental and offspring cohorts. GBI can indicate generational changes when calculated using different time or cohort data. The study clarifies that in the Tokyo metropolitan area the populations at micro-level are out of balance especially in such districts as detached-owned residential areas, commercial areas, or farming areas, and the imbalance is projected to continue until at least about 2020. This phenomenon is mainly led by the residential choice of the 1960's and 1970's cohorts most of whom were born in the Tokyo metropolitan area, and it will not be apparent at the macro-level and the community policies will have the more importance than ever.
