With reference to order of birth, which is closely related to the number in the family, the father's earnings seem especially inappro- priate as an index of economic pressure. Accordingly, for this corre- lation an analysis is made in Table 143 to show the relative mor- tal...ity in the groups with varying economic pressure after the influence of order of birth is eliminated. A study of this table shows that even after the elimination of order of birth as a factor the mortality in the group with the smallest per capita income from father's earnings, "less than $50," was over twice as high as in the group with the largest per capita income, "$400 and over."
