This article addresses the role of spatial interaction in social networks. We analyse empirical data describing a network of leisure contacts and show that the probability to accept a person as a contact scales in distance with ∼ d <Superscript> − 1.4</Superscript>. Moreover, the analysis reveals that the number...</superscript>
