not directly comparable with those that may be obtained from statistical
summaries of income tax returns. Income, as defined for federal tax

capital gains in tax returns. Furthermore, members of some families file
separate returns and others file joint returns; consequently, the income
reporting unit is not consistently either a family or a person."
