Abstract:

Recent work on the organized sources of network ties and on the social structural determinants of association are synthesized to produce several hypotheses about homophily. These hypotheses are tested with data on 304 face-to-face groups from 10 communities. We find that friends are more similar on status dimensions than chance and that this homophily is produced both by the restricted opportunity structure offered by the group and by homophilous choices made within the group. Organizational heterogeneity leads to substantially greater dyadic status distance within the organization, while organization size consistently reduces dyadic status distance. At a given level of diversity, a larger group will permit more homophilous friendship pairing. However, correlated status dimensions create little reduction in dyadic social distance. In general, homogeneity within groups is the overwhelming determinant of homophily.
