Need of Family Histories

1914 Journal of Heredity  
WHAT A EUGENIC REFORM WOULD MEAN The accompanying charts show respectively the distribution of economic classes in present society (at the left) and the distribution that would result were size of family to be roughly proportional to income and native ability; were also negative eugenics to be used to prevent the multiplication of the defective; and were the educational opportunities of the industrial classes greatly increased (at the right). These charts are merely suggestive: proportions and class designations are not exact. (Fig. 18.)
