Baltimore City has some of the highest incidence rates of Adverse Childhood Experiences, or ACEs, in Maryland. ACEs include experiences of child maltreatment and other family problems such as domestic violence and parental incarceration. Not only are these ACEs common, but they frequently co-occur. The cost of ACEs to the individual—and to society—is enormous. ACEs are associated with increased risk for a broad range of negative social outcomes, psychiatric and substance use disorders, health risk behaviors, and medical health problems.
