This paper examines the relationship between social policy and the phenomenon of runaways and their health. Through an exploration of the literature and reference to empirical studies, including the author's own work, it provides background and establishes the relationship between being in care and running. Assumptions which guide social policy as well as the service delivery itself provide an explanation for the runaway--child welfare connection. The paper concludes with discussion of the implications and recommendations for a policy shift with respect to services for adolescents.
