The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
54% of Tucson Conquistadores Foundation’s revenue is contributions — more earned-revenue than three-quarters of its peers (100% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 3 funders to 9 funders, grant income rose $29k → $96k.

From the IRS filings of Tucson Conquistadores Foundation’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
Tucson Conquistadores Foundation has a broad base — no single funder exceeds 18% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
42% 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 Tucson Conquistadores Foundation.
Largest funder’s share by year: 2017 65% · 2018 100% · 2019 50% · 2020 42% · 2021 42% · 2022 42% · 2023 31% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $119k arriving through sponsors registered in 6 statesis 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.
