Abstract
The aim of this study is to make clear the structure of the demand for assembly facilties from the viewpoint of socialization in leisure life, and this study pays attention especialy to informal group formation. The conclusions in this paper are as follows; 1) Among persons over eighteen years old, the ratio who take part in some groups in leisure life is about 20-30%, and this ratio is increasig. As to the future tendency of this ratio, this paper proposes five expectations with regard to the reason of nonparticipation and to the desire. 2) Among participators, the ratio who take part in plural groups is about 30%. But the number of groups in participation relates to the frequency of group activity, and the increase of frequency decreases the number of groups. 3) Group formation in leisure life has striking continuity, in spite of its informal character. 4) Each city has its own qualitative structure of group formation in leisure life, but quantitative structure is much the same. 5) Taking account of those who desire to take part in some groups, the qualitative structure of group formation in leisure life will differ from the present condition.
