1. In a previous paper, the writer discussed statistically the emigration regions in SHIKOKU and determined the factors causing emigration from each regions. The geographical factors in any region should not be consi-dered individually, but as a whole; from the geographical point of view, they must be attributed to the structure of the regions be thought of in combination.
The writer, as in the SHIKOKTJ, study listed (1) the ratio of farm, (2) that of subsidiary farmers and (3) that of small farmers as facors of emigration And tried to determine relationshipt between the factors.
2. In this paper KANTO cosznprises, six prefectures of the KANTO District and four prefectures in SOUTHERN CHUBU, (Shizuoka, Aichi, Mie and Wakayama). The latter two generally belong to the KINKI District, but are included because of their similarity to the other two io several aspects.
3. At first, simple correlation coefficients between the ratio of the emi-grants to all farmers and to each of the three factors were calculated. The correlation of the farm is very low, therefore it cannot be considered as a cause of emigration. In regard to Vie otter two, their correlations are all lineal (Table 1.) and the test by correlation covariance demonstrates that -the regression coefficients bi in the equation Y=b
0+biXi are all significant.
4. The multiple correlation coefficients between Y and X
1, X
2 and the multiple regression equation were determined as follows: ry.X1X2=0.62 in KANTO ry.XlX=0.74 in CHUBU _??_ The estimated values of the emigrants by the eq uation almost coincide with their actual values (Fig. 1, 2, 3, 4.), therefore, by the test of the partialre gression coefficients, the causes of emigration can be determined in each region.
