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.
Government-grant reliance: 2019 63% · 2021 54% · 2022 65% · 2023 59% · 2024 54% · 2025 53%. Grants only. Government contracts and fees sit inside program revenue.
92% of Loudoun Museum Inc’s revenue is contributions — more donation-reliant than the typical peer (64% for the typical peer).

From the IRS filings of Loudoun Museum Inc’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
Loudoun Museum Inc leans on a few funders — its largest provides 43% of grant income and the top three 99%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
56% 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 Loudoun Museum Inc.
Largest funder’s share by year: 2017 100% · 2018 90% · 2019 100% · 2020 100% · 2021 97% · 2022 95% · 2023 61% — diversifying over time.
“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
56% of Loudoun Museum 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 $86k that is directly attributable, 98% of it comes from Virginia funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $109k arriving through sponsors registered in 3 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.
