It takes a safe village to raise a child—a commentary on Dana McCoy et al.

This commentary on the study by McCoy et al. (2023) examining the negative effects of neighborhood violence on the development of toddlers growing up in the city of São Paulo (Brazil) interprets these outcomes from the perspective of ecological system theory, modern brain research, and the prospect of resilience. We argue that societies should give children the opportunity to grow up in a safe and sufficiently affluent social environment in order to give them a chance to achieve their full developmental potential. Governments and the health care system should, therefore, first and foremost invest in safe and stimulating child-rearing environments, informed by scientific research.
