This survey was conducted by the Gallup organization on the volunteering and giving behavior of U.S. teenagers as a supplement to a national survey on giving and volunteering among U.S. adults. Information was obtained from in-home personal interviews with 301 teenagers from 14 to 17 years of age. Results indicated that 58 percent of teenagers volunteered an average of 3.9 hours per week, and approximately 29 percent of all voluntary assignments were performed as extra-curricular activities at school. The most frequently reported volunteer tasks were babysitting, assisting the elderly or handicapped, or serving as an aide or assistant to a paid employee. Primary institutions for voluntary activities were schools and religious institutions. The most frequently cited reasons teenagers gave for why they started to volunteer were that they thought they wanted to do something useful, and they thought they would enjoy the work. Schools and membership in religious institutions were found to have a major influence on the incidence of volunteering and contributing. Teenagers expressed more confidence in health and social service organizations, federal charitable appeals, public higher education, and the media, than in all other major institutions of society, including government, organized labor, or Congress. (Appended are a summary of the volunteering and giving behavior of adolescents compared with adults, areas of volunteering and giving, the methodological statement, and the survey questionnaire.)
