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 $46M to $70M (+53%).
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: 2017 2% · 2018 3% · 2019 4% · 2020 17% · 2021 4% · 2022 12% · 2023 58% · 2024 20%. Grants only. Government contracts and fees sit inside program revenue.
72% of INTERNATIONAL AFRICAN AMERICAN MUSEUM’s revenue is contributions — more donation-reliant than the typical peer (58% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 6 funders to 39 funders, grant income rose $323k → $2.6M.
29 of 110 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 52% 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 INTERNATIONAL AFRICAN AMERICAN MUSEUM’s funders (the co-funder graph). Top 30 of 110 funders by total. 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
INTERNATIONAL AFRICAN AMERICAN MUSEUM has a broad base — no single funder exceeds 29% 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
53% 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 INTERNATIONAL AFRICAN AMERICAN MUSEUM.
Largest funder’s share by year: 2017 46% · 2018 30% · 2019 70% · 2020 37% · 2021 62% · 2022 25% · 2023 19% — 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.
How long its funders stay
33% of INTERNATIONAL AFRICAN AMERICAN MUSEUM's funders are still giving 3 years after their first grant; 42% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
52% of INTERNATIONAL AFRICAN AMERICAN MUSEUM'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 $13M that is directly attributable, 86% of it comes from funders outside South Carolina, across 20 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $14M arriving through sponsors registered in 17 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.
