We consider the structure of social network of university students, and analyze factors that lead to the network formation. Using the data from student survey and administrative information, we estimate econometric models that assume homophily and geographic closeness effect on the likelihood of being friends. Specifically, we estimate linear probability models with and without fixed effects, and logistic model for probability of a tie between two students. The results confirm the significance of such friendship formation factors as sharing the same study group, living in the same dorm, closeness of academic achievement and gender  homophily.
