Each of these statements is true except

A) Female-headed black families with children under 18 have a poverty rate of almost 47%.
B) Female-headed white families with children under 18 have a poverty rate of almost 35%.
C) All families receiving public assistance are poor.
D) All poor families receive public assistance.

Statement D is incorrect because not all poor families receive public assistance. There are various eligibility criteria for public assistance programs, and not all individuals or families who are considered poor by federal poverty standards meet these criteria. Additionally, some may not apply for assistance even if they are eligible.
