Table 2. Distribution of self-reported, within-group relations among occupational groups (Questions 4 and 5 in Table 1). Size refers to the number of individuals within respective occupation, Ratio refers to the ratio of observed vs. expected within-group relations based on an assumed random distribution of all relations, Rel/Ind refers to the total number of reported relations to individuals irrespective of their occupation, divided by the number of members within the group, and Rel/Ind in group refers to the number of reported within-group relations divided by the number of group members. The numbers in parentheses represent the probabilities (%) of acquiring a higher ratio, assuming independence between the occupational categories and probability for relational ties. For example, for the within-group ratio of businessmen (0.92), the probability of acquiring a higher ratio would be 64%.
