The main aims of our research are to restructure the region planning methods for agricultural community with sustainability. On this paper, we aim to figure out variable factors of time-series behavior of agricultural community from 1970 to 2000, and correlate those factors with geographical conditions. Using the census data in rural area, we got results as follows. 1. Time-series behavior patterns of agricultural community: Changes of agricultural community and regional economy are presented as "a degree of dependence on agricultural industry" and "a proportion of farm houses to the population in rural area". 2. The difference from district: From correlating time-series behavior patterns of agricultural community with geographical condition, distribution of the patterns are varied according to district of eastern Japan, western Japan, three major metropolitan areas.
