Pick your issue: academic achievement, drug use, female empowerment, race relations, obesity, mental health, medical costs. Engaging young people in sports can help communities tackle all of these, and many more. What’s more, it can yield benefits like community cohesion, citizen engagement, economic productivity, urban development, and help foster social-emotional skills like resilience and teamwork, respect for your opponents, and the rule of law. Give a kid a quality sport experience, and the evidence suggests that lives — and societies — can be transformed. So how can we trigger systems-level change that delivers opportunity to every child?
