As ever-increasing numbers of children live apart from their parents, how can policymakers and professionals who work with families address the emotional and financial needs of such children? The editors draw on research, policy and practice sources in order to identify a rich array of roles that nonresidential parents may play in the lives of their children. They also explore such issues as: variation in nonresidential parenting across ethnic groups; the financial implications of parenting separately; patterns of involvement of nonresidential parents; and implications for further research and social policy.
