A social network analysis (SNA) is a method to study and observe social structures of a particular population. It can be applied to various disciplines and at various scales. A basic social network is made up of nodes, which are the subjects, and edges, which show the connectivity between the subjects. The purpose of a social network analysis is to understand the connections and communication among a community of interest. Such an analysis can highlight key “connectors”, or individuals who play an important role within the community and find clusters of connections (see Figure 1 below as an example of an SNA).
