In this brief, the Sillerman Center explores Youth Philanthropy as a model with the potential to make grantmaking more democratic, inclusive, and responsive to the needs of underserved communities. It is also a model that, if more widely supported and expanded, could contribute significantly to the preparation of sophisticated future grantmakers who share social justice values. This brief explores the landscape of youth philanthropy in the United States, providing concrete examples of best practices in youth philanthropy, particularly for teenagers. We review youth philanthropy’s potential benefits for both communities and for young grantmakers themselves. We also offer recommendations to funders for how to best support youth philanthropy or how to expand and deepen their support for this growing practice.
