03Who funds it

Who funds it, year by year

2017 → 2023: the base broadened from 1 funder to 3 funders, grant income fell $15k → $10k.

From the IRS filings of FRIENDS OF CARBONE CANCER CENTER INC’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund FRIENDS OF CARBONE CANCER CENTER INC.
