A social network is a set of social actors (e.g. People, organizations, communities, nations) and a set of social relationships (e.g. Friendship/affect, communication, economic transactions, interactions, kinship, authority/hierarchy, trust, social support, diffusion, contagion, shared memberships) among them. Considering social relationships as a network call attention in some manner (e.g. Graphically, analytically) to the importance of the pattern or structure of the set of relationships.
The term is used to describe a social structure determined by such interactions. The ties through which any given social unit connects represent the convergence of the various social contacts of that unit. This theoretical approach is, necessarily, relational. An axiom of the social network approach to understanding social interaction is that social phenomena should be primarily conceived and investigated through the properties of relations between and within units, instead of the properties of these units themselves.
