Final answer:
The references provided discuss the financial and educational advantages of children from married households and the socioeconomic characteristics of single and divorced parents, but do not directly address whether children from single-parent households are less likely to have a child outside of marriage.
Step-by-step explanation:
The truth or falsity of the statement "Children from single-parent households are less likely to have a child outside of marriage themselves" is not directly answered by the provided information. However, the provided references suggest that children who grow up with married parents generally have more financial and educational advantages, and parental marital status is an indicator of advancement in a child's life. The statistics also indicate that never-married parents are often younger and have lower incomes, which could impact the life choices of their children. Official studies or sources have not confirmed whether children from single-parent households are statistically less or more likely to have children outside of marriage themselves. Such outcomes can be influenced by a multitude of factors including, but not limited to, socioeconomic status, level of education, cultural values, and personal choices.
