A national mail survey of adolescents between the ages of 12 and 17 (n = 876) was conducted immediately before the U.S. presidential election (October 2012) to investigate socialization agents that may correlate with political and civic engagement. The relative importance of potential correlates of engagement including demographics, parents, peers, schools, religion, traditional media, social networks, and digital communication were evaluated. Regression analysis revealed that civically engaged youth identify with a religion, participate in civic education activities at school and extracurricular activities, take action (e.g., boycotting or buycotting), develop attitudes about citizenship, and engage in online/social media political activities. Politically engaged youth come from higher income households, discuss news and politics, take action, and are very prone to engage in online/social media political activities. While a wider range of activities appear to be related to civic engagement, those who are politically engaged appear to have a strong interest in online media usage. Implications are discussed.
