This study aimed to determine the influential factors which relate with the stable change of population size in the local municipalities, using multivariate analysis such as multi-regression analysis. Drawing various data on green environment and city component factors from all cities in the Tokyo Metropolitan Region area in Japan, multi-regression analysis are executed in order to examine a relation between the change of population size (social increase) and relating with green environment factors. The following results are to be explained as of fundamental new findings. (1) The ratio of population (under 15 years old), the revitalization degree of industry, and the park area more than 1 ha show the strong relation with social increase raise. (2) The degree of the influence on a social increase is different depending on the distance from Tokyo Station, and it has been evident from 30 to 40 km. (3) Municipalities which have lot of parks of l ha or more in area and more of 0.25 per square kilometer in density show the good relation with social increase of recent ten years. Therefore, the index which relates with the existence of the park of more than l ha was considered as the key factor which relates with the realization of stable and positive change of population size.
