The study explored the effect of membership in nonpolitical voluntary associations upon the degree of political activity of members. In particular, the authors asked whether or not these effects were found in a relatively uniform pattern across different age groups. On the basis of the reported levels of political discussion in 14 types of nonpolitical associations, memberships were categorized as either apolitical or neopolitical. Apolitical associations provided absolutely no opportunity for political activity or discussion; neopolitical associations provided a small degree of opportunity for political activity or discussion. Participants were surveyed concerning the amount of political activity they engaged in, ranging from voting to attendance at political meetings and making political donations. Findings are that members of both neopolitical and apolitical associations are more politically active than nonmembers, and that members of neopolitical associations are more active than members of apolitical associations. Older respondents differed from the rest of the population only in that their levels of political work and political talk were somewhat lower than levels of younger members. Tables showing response data are included. (Author/AV)
