New research has underlined the view that family structure and stability matter for the welfare, happiness, and future outcomes of children.

According to a new report from the AEI-Brookings Working Group on Childhood in the United States, the evidence indicates that, on average, children who have (a) two parents who are committed to one another, (b) a stable home life, (c) more economic resources, and (d) the advantage of being intended or welcomed by their parents are more likely to flourish.

“In general, we believe that evidence suggests that marriage is the best path to the favorable outcomes highlighted above. Marriage is of course not the only path that allows children to succeed; many children raised by single parents and cohabiting parents thrive in life. Even so, in the United States marriage continues to be the institution most likely to combine the four benefits outlined above for the sake of children,” the report states.

The authors add: “Marriage matters to children. Having married parents typically means that children live in families with more resources, including more time with their parents, and with greater stability. While these factors in themselves point to a range of improved outcomes for children, the benefits of growing up in a family with married parents is more than a sum of these parts. Yet a long, steady decline in marriage rates over the past five decades means that more children are growing up in single-parent families. Today about one in four children ages 0–12 does not have married parents. While the decline in marriage has occurred across all demographics, more than one in three children whose mother has an education level of less than a college degree does not have married parents”.
