This is what the paper says:
"Total family income is the measuring stick used to determine levels of affluence achieved. This is defined as taxable income of head of household and spouse, taxable income of other family members of the household, and transfer income of head, spouse, and others."
Based on what I know about US tax, you don't have to pay taxes on the first $500k in gains for your primary house (if married), and inheritances usually aren't considered taxable income.
