The primary aim of this article is to analyze components of aggregate social capital in Greece. Through the comparison with other European countries, it is concluded that social capital in the country may be characterized as weak. In addition, similarities among South European countries are underlined. Finally, an index of social capital scores across Greek regions is created and presented. The need for further research is emphasized, regarding mainly the impacts of social capital on several aspects of Greek society, along with the formulation of the appropriate policies for strengthening it.
