Not all friends are created equal: Friendship ties across different social contexts in South Korea

Abstract

This study explores variation in composition and strength of close friendship ties across timing and contexts of tie formation. Analyzing South Korean survey data and comparing it with existing U.S. and Korean network data, we find both similarities and differences between friendship and non-kin discussion networks in the two countries. We show that schools are a crucial source of close friendships for Koreans, shaping homophily patterns. Additionally, we uncover substantial variations in tie strength across timings and contexts of tie formation. We discuss the implications of these findings, highlighting the role of social and cultural contexts in shaping personal networks.
