, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences …, and different network layers. At the individual level, homophilous tendencies are persistent across time and network … layers. Furthermore, we see assortativity in homophilous tendencies.

We show that the more central … minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks … tend to favor assimilation so that, for example, it is easier to assimilate in a complete network than in a star …
