Participation in formal and informal volunteering: Implications for volunteer recruitment

This study examines factors influencing “formal” volunteering (that is, to an organization) and “informal” volunteering (that is, volunteering carried out individually outside of an organizational context) and the relationship between these two activities. We hypothesize that formal and informal volunteering activities are positively interrelated but that they are shaped by different types of personal resources: involvement in social networks increases the likelihood of both types of volunteering, but human capital increases the likelihood of formal volunteering rather than informal. The bivariate probit regression results emanating from the Independent Sector's “Giving and Volunteering in the United States, 2001” survey are generally supportive of the hypotheses. The findings suggest that nonprofit and public organizations that involve volunteers consider the pool of informal volunteers as a fertile ground for recruitment and find ways to better utilize older Americans in formal volunteering. The results also suggest that volunteer recruitment through organizational membership may be an effective strategy.
