Our paper aims to demonstrate that social structure has significant impact on the formation of
interpersonal relations. We review and analyse the characteristics of ego-centric interpersonal
networks of Hungarians based on data from nationally representative adult population surveys
between the mid-1980’s up to 2015. We focus especially on core discussion networks, friendship
ties and weak ties and analyse how the transition to market economy influenced interpersonal
relationships. As expected, the large-scale social changes brought about by the transition
changed interpersonal networks as well. During the first decade of the transition (in the 1990’s)
one could not witness a significant change of personal networks, nonetheless the adaptation
process was easier for people supported by strong, traditional family ties. Non-kin ties, especially
friendships seem to gain significance at the expense of kin relationships. Overall, resources
available through weak ties seem to be decreasing.
