This study investigates parents' conception of children's play safety and danger in an urban setting. The paper proposes that parent's conceptions of neighborhood play safety are multi-dimensional constructs influenced by ethnic background, socio-economic conditions, household composition, sex of the child, and the physical features of the neighborhood. This investigation is divided into four stages: (I) an ethnographic phase; (2) interviews with 18 Caucasian and 18 Black-American families and; (3) case studies with six families. The final stage of the research will involve a critique of the research findings by the study's participants. The findings from this data will be useful for informing social policy on children's outdoor safety and the improvement of urban outdoor play opportunities.
