Fig. 2: Embeddedness structure and communications frequency at different levels of degree centrality.

A Frequency of calls to friends (family) increased (was relatively flat) with degree centrality. At each level of degree centrality, B egos in fully embedded families made more calls to family than those in non-fully embedded families (M = 40.68 vs. 20.76, p < 0.001). C Egos in completely unembedded family structures made significantly fewer calls to family than those in non-completely unembedded family structures (M = 3.10 vs. 35.13, p < 0.001). D Proportion of calls to friends the first week after the earthquake is greater for egos in non-completely unembedded vs. completely unembedded family structures (M = 0.944 vs. 0.732, p < 0.001). E Egos were more likely to first call a friend when they are in non-fully embedded vs. fully embedded family structures (0.664 vs. 0.800, p < 0.001). F Egos are less reciprocal when they are in completely unembedded vs. non-completely unembedded family structures (M = 1.945 vs. 5.113, p < 0.001). We observe consistent results for completely embedded vs. non-completely embedded, or completely unembedded vs. completely unembedded family structures for each dependent variable (see Supplementary Figs. 9–11 for analogous figures). N = 35,565 users from 11,855 three-person family plans; error bands denote 95% confidence interval.
