This report is based on an intensive 18-month ethnographic study of 47 young fathers enrolled in Public/Private Ventures' Young Unwed Fathers Pilot Project. It presents a detailed look at selected aspects of the lives of these fathers before and during program participation, as well as outcomes of the pilot intervention. Following an introductory chapter, chapter 2 describes the fathers who participated in the research, as well as their children, the mothers of their children, and their neighborhoods. Chapter 3 examines the men's experiences with fatherhood from the mother's pregnancy onward and presents findings on parenting outcomes. Chapter 4 presents education, training, and employment outcomes. Chapter 5 examines the material and financial support that fathers provided to their children informally; fathers' attitudes toward, and experiences in, the child support system; and outcomes associated with paternity declaration and formal support orders. Chapter 6 discusses the policy implications of the research findings. Appendixes present a summary of the project's initial implementation report, a profile of the sites involved, a sample selection and representativeness, cost analysis, and the length of stay and services received.
