What Boone County Historical Society does
Mission

As stated on its FY2025 Form 990.

$117,177 spent100% of program spending
The program described on its FY2025 Form 990. Program spending in total: $117,177.
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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2020 to 2021, from $981k to $1.9M (+92%).
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.
Government-grant reliance: 2019 5% · 2020 9% · 2021 50%. Grants only. Government contracts and fees sit inside program revenue.
19% of BOONE COUNTY HISTORICAL SOCIETY’s revenue is contributions — more earned-revenue than three-quarters of its peers (64% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2020 → 2023: the base narrowed from 3 funders to 2 funders, grant income fell $47k → $44k.
3 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 38% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $29k from one payer (the payer shares this organization's board, largest Boone County Community Foundation). These are real filings, and they are not money BOONE COUNTY HISTORICAL SOCIETY raised.
From the IRS filings of BOONE COUNTY HISTORICAL SOCIETY’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
BOONE COUNTY HISTORICAL SOCIETY leans on a few funders — its largest provides 58% of grant income and the top three 88%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
41% 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 BOONE COUNTY HISTORICAL SOCIETY.
Largest funder’s share by year: 2020 49% · 2021 100% · 2022 31% · 2023 77% — growing more concentrated.
“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
94% of BOONE COUNTY HISTORICAL SOCIETY's grant income comes from Illinois funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $101k arriving through sponsors registered in 3 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.
Against its field
BOONE COUNTY HISTORICAL SOCIETY's revenue fell 33% between 2017 and 2025.
