Table 2. Distribution of selfreported, withingroup 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 withingroup 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 withingroup 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 withingroup ratio of businessmen (0.92), the probability of acquiring a higher ratio would be 64%.
