In this table, the decrease of earnings of approximately $100 from class to class is striking. The average family income was as follows: AVERAGE ANNUAL FAMILY INCOME, BY NATIVITY OF HEAD OF FAMILY[228] NATIVITY AVERAGE FAMILY INCOME Native-born white of native father $865 Native-born of foreign father 866 Foreign-born 704 Footnote 228: _Ibid._, p. 136. Comparing the last two tables, and noting that while the average yearly earnings of native-born male employees of foreign parentage are $100 less than those of the native-born of native parentage, yet the family income of the native-born of foreign parentage is $1 more than that of the native-born of native parentage, the obvious conclusion might be that the native-born of foreign parentage are more inclined to rely upon some one besides the head of the family for part of the income than are the native-born of native parentage. Closer examination, however, proves that this is not the case. The following table gives the percentages of families of different nativities which receive the entire income from the husband. PER CENT OF FAMILIES HAVING ENTIRE INCOME FROM THE HUSBAND, BY NATIVITY[229] NATIVITY PER CENT Native-born white of native father 58.4 Native-born of foreign father 61.3 Foreign-born 38.0 Footnote 229: Rept. Imm. Com., Imms. in Mfg. and Min., Abs., p. 139. Thus there is a smaller proportion of families among the native-born of foreign fathers who rely upon other members of the family than the husband for part of the family income than of the native-born of native father. It appears that the explanation of the peculiarity which has been noticed must be either that only the more prosperous of the native-born of foreign parentage are heads of families, or that those families of this class which do receive income from other sources than the husband receive a much greater total amount than among the native-born of native father, so as to raise the average. The former explanation seems the more probable, for while 67.3 per cent of the male native-born white employees of native fathers, 20 years of age or over, were married, only 56.5 per cent of the native-born of foreign fathers of the same age were married. Native-born employees of foreign parentage who are old enough to be the heads of families are predominantly representatives of the old immigration, and hence stand high on the wage scale. The very small percentage of families among the foreign-born which derive their entire income from the husband indicates the extent to which the children of this class contribute to the family support, and also the extent to which boarders are taken.
