Migration, mixedness, and the partner’s role in core discussion networks

Abstract

Research into migration and social networks has suggested that migrants are relationally more vulnerable than non-migrants, especially those in endogamous couples. However, non-probability samples and lack of data about partners’ networks have often impeded rigorous testing. This paper analyses the influence of migration and mixedness (unions between two persons from different geographical origins) on some compositional and structural measures of the core discussion networks of the adult population in Spain, paying special attention to the partner’s role. Data from the 2013 Spanish General Social Survey (SGSS) were used. A graph census shows the predominance of complete graphs both for endogamous and exogamous couples, but more clearly in the case of natives. Multivariate models prove that, in general, Spaniards in mixed unions seem less partner-dependent, whereas endogamous immigrants seem the most affected by the effects of the geographical mobility on relational vulnerability.
