Do existing linkages between types of community groups exist? Yes, they do. We have found that the community’s churches, family, and hobby organizations have some common members. It may be a bit surprising that the political and professional groups do not appear to be interconnected, but these groups may also be more specialized (e. g. a local chapter of the bar association) and thus may not have tremendous cross-organizational appeal or need.
