This report provides findings on the adverse childhood experiences (ACEs) of Philadelphia residents. Past studies, including the seminal 1998 Kaiser study by Felliti and Anda, have confirmed the negative impact of ACEs—such as physical, emotional and sexual abuse and household dysfunction, on health behaviors and health outcomes in adulthood. However, most of these findings have been confirmed in studies composed of primarily white, middle-class, and highly educated individuals. The Institute for Safe Families (ISF) formed the ACE Task Force in 2012 with an interest in examining the prevalence and impact of ACEs in Philadelphia—an urban city with a socially and racially diverse population. A total of 1,784 adults completed the Philadelphia Urban ACE Survey for a response rate of 67.1 percent, and found a higher prevalence of ACEs than found in previous studies.
