This book is concerned with the question of how families matter in young people’s development - a question of obvious interest and importance to a wide range of readers, which has serious policy implication. A series of key current topics concerning families are examined by the top international scholars in the field, including the key risks affecting children, individual differences in their resilience, links between families and peers, the connections between parental work and children’s family lives, the impact of childcare, divorce, and parental separation, grandparents, and new family forms such as lesbian and surrogate mother families. The latest research findings are brought together with discussion of policy issues raised.
