The organization over time
Each line starts at 100 in 2023, so what you read is the shape rather than the size: 150 means half as much again as 2023, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 61% 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 MATH CIRCLES OF HOUSTON’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.
How concentrated its funding is
MATH CIRCLES OF HOUSTON leans on a few funders — its largest provides 39% of grant income and the top three 100%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
61% 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 MATH CIRCLES OF HOUSTON.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.
Where its funders are
61% of MATH CIRCLES OF HOUSTON'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 $60k that is directly attributable, 100% of it comes from Texas funders.
Funder states come from each funder’s own filing. $92k arriving through sponsors registered in 2 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.
