While the volunteer rates of teenagers remained quite low in 1974 and 1989, we find that volunteering rates for individuals aged 16 to 19 actually doubled between 1989 and [2005] — to a rate that exceeds the national volunteer rate . . . . Increased enthusiasm for volunteering among today’s young people is reflected in other research as well. For example, the Higher Education Research Institute’s (HERI) found an all-time high in the percentage of first-year college students who indicated that there was a high probability that they would volunteer or participate in community service sometime during their college careers. The Corporation’s College Students Helping America report recently highlighted a 20 percent increase in the number of college students volunteering between 2002 and 2005, while the University of Michigan’s Monitoring the Future study also finds a rising trend in volunteering among teens. -Corporation for National and Community Service, “Volunteer Growth in America: A Review of Trends Since 1974”
