SPSS's data-handling facilities make it useful for studying ego-centered networks. Such networks are useful for studying a variety of subjects, such as social support, personal community, and an organization's relationships. We show how analyses of ego-centered networks are best done by starting with two data sets: (1) focal individuals and their ego-centered networks; (2) network members and their ties with focal individuals. We show how to link these two data sets to (a) calculate summary information about each ego-centered network; (b) combine focal individual, tie and network data. Note: This article has been developed from "How to Use SAS to Study Ego-Centered Networks" (Wellman 1992a), itself a thoroughly revised version of Wellman and Baker (1985).
