Taking the position that there is a developmental process in the forma
tion of citizenship, the authors reviewed studies that reported a link
between youth's participation in organized activities and civic behav
iors 15 or more years later in adulthood. Data uniformly showed that s
tudents who participated in high school government or community servic
e projects, meant in the broad sense, are more likely to vote and to j
oin community organizations than are adults who were nonparticipants d
uring high school. Results support the authors' view that participatio
n during the youth era can be seminal in the construction of civic ide
ntity that includes a sense of agency and social responsibility in sus
taining the community's well-being.
