From the IRS filings of GREATER WYOMING BIG BROTHERS BIG SISTERS’s funders (the co-funder graph). Association, not causation.

Funder states come from each funder’s own filing. $209k arriving through sponsors registered in 4 states 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.
