In this project with Jim Ferris (USC Price), we are exploring the grantmaking activity of foundations who give to Los Angeles nonprofits. The figure below shows links between foundations who gave to the same nonprofit in 2007. Using a Girvan-Newman algorithm, I detected “latent communities” or dense subnetworks within the larger network and colored the foundations accordingly. Node size is based on size of grantmaking. We plan to follow the grantmaking patterns from 2003 to 2007 in order to explore the various roles that foundations play within their own fields.
