It is usually thought that food pattern of a population is influenced by their enviromental situation. In order to make clear the relationship between food consumption and environmental traits, the author tried to study the influence of both traits of residence and occupation on food consumption. The subjects consist of 428 households in Gifu Prefecture which are derived from 3 areas of urban, suburban and rural area, and then are classified into 4 groups by occupation of household head (farmer, wage labor, individual proprietor and office worker). For a statistical method, the author used principal component analysis with external criteria of residence and occupation. The results are as follows. 1) It was found that the deciding factor of food consumption concerning the external criteria was different dietary habit between tradition and modernization. The traditional food pattern meant much consuming of rice, fish, bean and vegetables, and a few consuming of bread, meat, egg and dairy products. The traditional food pattern was performed on households of rural area and wage labor. On the other hand, the modern food pattern meant the just contrary, and was performed on households of urban area and office worker. 2) From the residuals excluding effect of the external criteria, two factors were extracted. They were "polyphagia" and "modernization" which were almost the same as that reported by Toyokawa for both data from national Nutrition Survey 1971 and community nutrition survey for women in Tokyo suburban area 1980. In addition, it was suggested that the aging factor was influential to food pattern of "modernization".
