The idea that equal education exists in the United States is a misconception, and positive youth development programs are a proposed response to inequitable education. Youth development programs have the potential to increase one's social capital, particularly for youths who are marginalized by inequitable access to quality education. The study described here focused on the contribution of urban positive youth development to social capital and social justice. Findings indicate that 4-H initiatives related to social capital are reaching marginalized youths. However, barriers are preventing 4-H from reaching these youths adequately and/or consistently.
