5. Dr. Alice Hamilton, in a Chicago study of I,500 families, found that the infant death-rate in large families of six children and over was two and one-half times greater than in small families of four children or less. Was that an indication that infant mortality rises with fecundity or was it one of many indications that the better-to-do have smaller families? In any case, should such statistics always include the statement of the social standing and the income of the groups studied?
