This marks the 20th annual resource tracking publication from Funders Concerned About AIDS (FCAA) on philanthropic support to address HIV and AIDS. The report relies on grants lists submitted directly by 72 funders (representing 92% of the total HIV-related philanthropic funding tracked by FCAA), as well as publicly sourced grants information from funder websites, grants databases, annual reports, U.S. Internal Revenue Service (IRS) Form 990 returns, and Candid’s Foundation Maps grants database (representing the remaining 8% of funding in the report). This report specifically captures HIV-related funding from philanthropic organizations around the world; it excludes any government funding to address HIV and AIDS, including domestic government, bilateral, and multilateral support.
