Facebook social graph, application installations and users, events, groups at

Two datasets (collected April-May 2009) which contain representative samples of ~1 million users Facebook-wide, with a few annotated properties: for each sampled user, the friend list, privacy settings, and network membership are included. A third dataset ( collected Feb 2008) includes a bipartite graph that represents application installations by Facebook users. A fourth dataset with Daily Active Users and application installations over 6 months (collected Sept 2007-Feb 2008). A fifth dataset that includes a representative sample of users obtained using multigraph sampling (collected July 2010).
