03Who funds it

Who funds it, year by year

2020 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $47 → $142.

1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 66% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

From the IRS filings of FRIENDS OF THE CAESTECKER PUBLIC LIBRARY’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.

the vertical line marks half of all grant income — 1 funder to its left

66% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. 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 THE CAESTECKER PUBLIC LIBRARY.

Where its funders are

66% of FRIENDS OF THE CAESTECKER PUBLIC LIBRARY's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $100 that is directly attributable, 100% of it comes from Wisconsin funders.

WI

Funder states come from each funder’s own filing. $192 arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. 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.
