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.
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 $16M to $20M (+24%).
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 5% · 2018 3% · 2019 1% · 2020 6% · 2021 9% · 2022 8% · 2023 7% · 2024 1%. Grants only. Government contracts and fees sit inside program revenue.
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

5 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 14% 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 SIGMA XI THE SCIENTIFIC RESEARCH HONOR SOCIETY INC’s funders (the co-funder graph). Association, not causation.

SIGMA XI THE SCIENTIFIC RESEARCH HONOR SOCIETY INC leans on a few funders — its largest provides 65% of grant income and the top three 91%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
84% 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 SIGMA XI THE SCIENTIFIC RESEARCH HONOR SOCIETY INC.
Largest funder’s share by year: 2017 95% · 2018 100% · 2019 91% · 2020 81% · 2021 53% · 2022 47% · 2023 93% — 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.

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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $218k arriving through sponsors registered in 5 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.
