Social networks form the backbone of social and economic life. Until recently, however, data
have not been available to study the social impact of a national network structure. To that …

In many social networks, there is a high correlation between the similarity of actors and the
existence of relationships between them. This paper introduces a model of network …

Most research on segregation in social networks considers small circles of strong ties, and
little is known about segregation among the much larger number of weaker ties. This article …

In this paper, we explore the potential implications of geographical variability for the
structure of social networks. Beginning with some basic simplifying assumptions, we derive …

The uneven distribution of wealth and individual economic capacities are among the main
forces, which shape modern societies and arguably bias the emerging social structures …

We use de-identified and aggregated data from Facebook to explore the spatial structure of
social networks in the New York metro area. We find that a substantial share of urban …

Recent empirical studies using large-scale data sets have validated the Granovetter
hypothesis on the structure of the society in that there are strongly wired communities …

Motivated by empirical evidence on the interplay between geography, population density
and societal interaction, we propose a generative process for the evolution of social …

Social network structure has often been attributed to two network evolution mechanisms—
triadic closure and choice homophily—which are commonly considered independently or …
