Among children in two-parent families, those living with both biological parents in a low-conflict marriage tend to do better on a host of outcomes than those living in step-parent families. Outcomes for children in step-parent families are in many cases similar to those for children growing up in single-parent families.[5],[6] Children whose parents are divorced also have lower academic performance, social achievement, and psychological adjustment than children with married parents.[7] Reliance on kin networks (for example, living with grandparents) can provide social and financial support for some families, particularly single-parent families. However, the evidence suggests that children who live in households with single mothers in some cases fare better, and in other cases worse, when also living with a grandparent.[8]
