Communities are not all created equal: Strategies to prevent violence affecting youth in the United States.

We describe violence in the United States (US) and solutions the Urban Networks to Increase Thriving Youth (UNITY) Initiative has developed, led by Prevention Institute, a US non-governmental organization (NGO) and authors of this article, with initial funding from the US Centers for Disease Control and Prevention (CDC). Safety distribution across populations is unequal, while public health research has identified aspects of community environments that affect the likelihood of violence, or risk and resilience factors. An overwhelming number of risk factors have accumulated in some US communities, disproportionately impacting young people of color. US policies, systems, and institutions powerfully shape how and where these factors manifest. Violence is preventable, not inevitable. We argue that comprehensive strategies for improving community environments can reduce violence and promote health equity. We present lessons, tools, and frameworks that UNITY cities use to adapt for international application, including multi-sector collaboration, strategies for influencing policy and legislation, and strengthening local violence prevention efforts.
