Final answer:
Less than 46% of African American households are headed by both a mother and a father, considering the high rate of single-parenting among this demographic and the general decline in married households.
Step-by-step explanation:
The percentage of African American households that are headed by both a mother and a father. Based on the given data, it is notable that single-parent households have been on the rise and that Black female-headed households comprise approximately 54% of all Black families with children. Furthermore, since 1960 the number of households in America headed by married couples has significantly decreased from 66% to about 45% by 2010. Given this data, although a direct percentage of African American households headed by both parents is not provided, it is reasonable to assume that less than 46% of African American households are currently headed by both a mother and a father, given the high prevalence of single-parenting among this demographic and the overall decline in married couple households.
