the vertical line marks half of all grant income — 1 funder to its left
82% 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 INTERNATIONAL ASSOCIATION OF INDIANAPOLIS 500 OLDTIMERS INC.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

Where its funders are
82% of INTERNATIONAL ASSOCIATION OF INDIANAPOLIS 500 OLDTIMERS INC'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 $10k that is directly attributable, 100% of it comes from Indiana funders.
Funder states come from each funder’s own filing. $45k 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.
