Abstract

It is well-known that space plays an important role in social networks, with pairs of geographically close individuals being more likely to have a connection than those far apart. However, lack of available data has meant that the spatial properties of larger social groups are as yet less well-understood. Do social communities tend to be geographically tight, even in the age of easy long-distance communication? How is the mobility of individuals and the places they frequent related to the existence of these groups?

Thanks to information about users' fine-grained location from increasingly geographically-aware online social services, we can start to investigate these questions. We will present some results from our initial analysis of the spatial properties of social groups in location based online social networks, and discuss how the answers could not only be interesting from a sociological perspective, but also have potential applications in online social services as mobile computing continues to expand.
