Civic service appears to be a global phenomenon. The growth of service may warrant a distinct field of study in which a comparative knowledge base could inform development and implementation of policies and programs. In this article, the authors summarize results of a global assessment of civic service. Searching by country and using information from organizational memberships, publications, and the Internet, 210 civic service programs were identified in 57 countries. This study has many limitations, raising more questions than it answers. Nonetheless, it is the first worldwide empirical glimpse of service, shedding light on several key questions: What are the current status and forms of civic service? What are its structures, goals, and effects? This introductory article of the special issue frames these questions for consideration by the authors, who identify historical and cultural determinants, forms, and mediators of civic service in different regions of the world.
