The nation faces an obesity crisis, especially among low-income children and children of color. Today, nearly one-third of children and adolescents are overweight or obese, and physical inactivity is a leading cause of this epidemic. Equitable transportation policy that fosters healthy, opportunity-rich communities has a critical role to play in reversing childhood obesity. This toolkit provides information to help communities across the United States advocate for and offer safe, effective, and affordable transportation systems for all children. The information provided will present tools, resources, and promising solutions to help ensure investments in transportation are made equitably in order to guarantee that underserved communities from urban and rural areas across the country can access the resources they need to lead healthy lives.
