Supplementary Information:
Figure SA1. Based upon the groupings uncovered through the hierarchical clustering algorithm, we categorized the name generators. We then selected one name generator from within each group in order to create a subset of name generators that would maintain the greatest proportion of the total network using a smaller number of name generators.
Regression models used to derive homophily values shown in figures below (Tables SA3-SA16): We used regression models to test whether trait similarity between ego and alter significantly predicted the chance that ego would name alter as a social contact. We quantified the association between social ties and similarity for each trait across the 12 name generators using a dataset composed of all possible nominations within each village (n = 4,197,904)34. Of these, there were a total of 80,838 observed nominations across all of the name generators in the dataset. Statistical analyses consisted of a logit form of a general estimating equation in which separate regression models were run for each of 16 traits of interest in order to predict ties for each of the 12 separate name generators. The dependent variable for the name generators was 1 if person i named person j as a social contact in that name generator (for instance if i names j as someone to whom they go for advice), and 0 otherwise. The main independent variables in these basic models included a measure for the trait of interest for the person i (the “ego”), a measure for the trait of interest for person j (the “alter”), and a measure of the similarity of their traits (this is the homophily measure). For example, for gender, we ran 12 different regressions: one for each name generator. Each regression included a variable for ego’s gender, a variable for alter’s gender, and a variable indicating whether or not they had the same gender. These three variables allow us to measure how much a trait predicts the sending of nominations (do women name more social contacts than men?), the receiving of nominations (are women named more often than men?), and the extent to which homophily on the trait plays a role (are same-gender social ties more frequent than opposite-gender?). To measure similarity for continuous traits we took the absolute value of the difference between ego’s and alter’s measures and then coded each dyad as 1 if it was below the median difference in values and 0 if it was above. Because each ego was represented in the dataset multiple times, we adjusted the standard errors by using a general estimating equation, clustering on the ego. Finally, all models included a binary control variable for “same household or not” for each dyadic observation to adjust for the fact that certain traits such as latrine ownership will be the same for those in the same household, while others traits such as education may be very different.
Figure SA1. Regression analyses in Tables SA3-SA19 provide estimates of the odds that an alter was nominated in any name generator, conditional on specific characteristics of the alter (shown below each plot). Most plots show that higher status alters are more likely to be named than lower status alters (Ball & Newman, 2013).

Odds of alter being named conditional on alter's characteristics
Figure SA 2. Regression analyses in Tables SA3-SA19 provide estimates of the odds that an alter was nominated in any name generator, conditional on specific characteristics of the alter (shown below each plot). Most plots show that lower status egos are more likely to name social contacts than higher status egos (Ball & Newman, 2013)
