Purpose and Activities

The John D. and Catherine T. MacArthur Foundation supports creative people, effective institutions, and influential networks building a more just, verdant, and peaceful world. MacArthur is placing a few big bets that truly significant progress is possible on some of the world's most pressing social challenges, including over-incarceration, global climate change, nuclear risk, and significantly increasing financial capital for the social sector. In addition to the MacArthur Fellows Program, the foundation continues its historic commitments to the role of journalism in a responsible and responsive democracy, as well as to the strength and vitality of its headquarters city, Chicago.
