This chapter assesses whether and how the rise in single parenthood influences child well‐being. It first describes the types of family structure experienced by children in different OECD countries, and moves on to explain why single‐parent family structure
may influence child well‐being. A meta‐analysis follows, drawing on a large number of studies and comparing the effects of single parenthood across countries and by well‐being dimensions. The penultimate section of the chapter discusses new techniques
to identify causality in the literature, while the final section examines policy implications.
