出稼ぎの疫学 (VII)

1965年～1975年 (10年間) の出稼ぎの変動

抄録

On the basis of the 1965 and 1975 statistical data of the Ministry of Agriculture and Forestry, the author analyzed in national and regional terms what changes took place during these ten years and came to the following general conclustion.
1. The numbers of “dekasegi” farm households and farmers conspicuously decreased from 1965 to 1975 in a national perspective. The number of “dekasegi” farm households which was registered at 382, 279 in 1965 dropped to 178, 000 in 1975. Analyzed in terms of prefectures, this phenomenon has resulted from a drastic drop in the number of “dekasegi” farm households in prefectures other than Akita and Aomori, where there have been proctically no fluctuations in the number of “dekasegi” farm households in the last 10 years.
2. The prefectures in which powerful measures for “dekasegi” farm households, judging from the 1975 new data, are Aomori, Akita, Iwate, Yamagata, Niigata and Kagoshima.
3. The rate of “farm households” at the prefectural level is not so high, to be sure, but the prefectures in which there exist special areas featuring high rates of “dekasegi” farm households have been identified. These prefectures are Hyogo, Miyazaki, Kumamoto, Nagasaki and Ehime Prefectures.
4. To decrease the number of “dekasegi” farm households, the author theoretically corroborated, on the basis of the conditions of “dekasegi” farm households in Shizuoka, Akita and Kagoshima Prefectures, that the prerequisite is to increase the number of constantly working farm households.
