Resourcing Girls to Thrive is the outcome of a research process to address significant gaps in the understanding of the adolescent girls’ funding landscape. This research process brought together the contributions and insights from girls from across the world, feminist adolescent girl funders who are resourcing national, regional, and global efforts, as well as a broad range of key stakeholders spanning academia, civil society, philanthropy, and government who are coming from the children’s, women’s, and youth funding fields.
