According to the U.S. Census Bureau, nearly 7 million children are left home alone after school each week when delinquent behavior most frequently occurs - between the hours of 3 p.m. and 6 p.m. Without supervision, young people are more likely to be at risk of engaging in dangerous behavior, while youths who participate in after-school and youth development programs are less likely to use drugs, drink alcohol, become sexually active, or smoke and are more likely to have stronger interpersonal skills, higher academic achievement, and healthier relationships with others.
