In 2014, the Russell Sage Foundation launched research collaborations with the W.K. Kellogg Foundation and the John D. and Catherine T. MacArthur Foundation. Over the last two years, 7 projects have been co-funded with the Kellogg Foundation and 9 projects have been co-funded with the MacArthur Foundation.
The Foundation occasionally make grants on topics unrelated to its major program themes. These often deal with the Foundation's longstanding interest in strengthening the methodology of social science. Some grants round out work begun under previous programs, and others may lead to new programs.
