In this study, We select depopulated municipality of Shimane prefecture in which population especially decrease as a subject of investigation and perceive various condition of population dynamics by making agricultural villages which is minimum regional society of a unit for analysis. And we make patterns of population. We realize a necessary condi-tion which dedicate the patterns of population by perceiving the relation between the patterns of population and (1) conditions of land location, (2) conditions of agriculture and (3) iconditions of social organization.
We are to realize a terms of planning for leading social vigor from the view of conserving population. Conclusions are as follows:
1. There are two population patterns to be planning standards, one is stable pattern, the other is advanced aging pattern in early stage changing of structure afterward.
2. We put terms contributing stability of population in villages in order. (1) Fluctuation of population have a close re-lation with the internal and marginal condition of convenience represented by accessibility to institutions and frequen-cy of traffic plying rather than external condition of relation between village and city.
(2) We confirm that social vigor tend to be high in villages in which population are preserved stably, in which com-ponent ratio of old people is high but workable population are preserved and which is in adverse conditions of low convenience. Thus in agricultural villages of depopulated area there are spontaneous effort making vigorous village by making community in the inside of village and this have a relation with stability of population.
3. As a result, maintaining social vigor in villages make up for disadvantage of convenience and there are possibility to conserve population including advanced aging village.
