UNICEF estimates that 1 in 7 children worldwide experience violence that affects their physical and mental health. In the United States, 1 in 7 children experienced child maltreatment in 2022, and 8% of adults report 3 or more ACEs. The overlap between these exposures and documented barriers to recognition sets the stakes for healthcare, schools, and child protection systems.

Interpretation
Systems & Policy Interpretation
Across Systems and Policy, the data show that while adoption of digital infrastructure is widespread with 91% of U.S. hospitals using EHRs and 68% of behavioral health organizations using electronic case management, only 37% of states report statewide protocols for screening children for social determinants or violence risk, and this uneven policy coverage remains a key barrier.
