The question for us however is as to the number of girls above school age and still unmarried who, because of family poverty, must find some form of wage-earning occupation. Turning to the vital statistics provided by the government (1914), we find that in 1908 there were 2,496,142 girls between ten and fifteen years of age, and 2,180,408 young women between fifteen and twenty years of age. But how many of these are married? Again relying on government statistics for the same year, we learn that only 199 girls under fifteen had been married, whereas 193,978 had married under twenty years of age. In view of the fact that 709,021 marriages took place between twenty and twenty-five years of age, it is altogether probable that, of those married under twenty, a large majority were married in their nineteenth year. Remembering that many do not marry until the twenty-third or twenty-fourth year, we can confidently assert that there are over 4,000,000 unmarried girls and young women between the ages of ten and twenty-five; and, as 58 per cent. belong to the farming class, we have in the vicinity of 3,000,000 girls who belong to families of such economic state that they, no less than the boys, must contrive in some way to earn a share at least of their own living. Girls of fifteen and upwards in farmers' families help their fathers in the lighter forms of agriculture, planting the rice, as we have seen, and reaping and threshing the crops. But the small acreage to each family barely provides work enough for the man, much less for the half-grown boys and girls, hence the need of finding something besides the agricultural work for the growing family. The younger children (under fifteen) are pressed into lighter farming, and such household duties as are within their strength and ability, as cooking and caring for the still younger children; while the older children and the mother help the father, or take up some domestic industry, such as the rearing of silkworms, reeling of silk, spinning of thread, and weaving of silk and cotton fabrics, or similar work which can be easily and profitably done in the house in spare hours. Hence has come the widespread practise of household industries, by which the female members supplement the family income. There were, in 1907, 1,628,000 members of farming families who were earning a part of their living in this way. This condition has prevailed for many generations, and is the secret of the wonderful development of the arts and home industries in Japan.
