This site was sponsored by a major philanthropic funder of community development—the John D. and Catherine T. MacArthur Foundation—in part to help guide its own strategies for long-term investment in selected neighborhoods of Chicago, the Foundation's hometown (see "About Us"). So we prepared all three of the knowledge-in-action briefs to highlight clear messages for those whose financial and other supports help make community development possible. The briefs and other materials can help you prepare materials for foundation staff or board members who need concise, accessible introductions to complex issues (for example to make strategic choices about an initiative or grant program focus), for grantees making tough decisions about their work, for evaluators you may engage to help design or assess local change efforts, and for trainers or others who help build capacity to advance your program goals.
