The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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.
99% of THE JANSEN DE VRIES SYNDROME FOUNDATION INC’s revenue is contributions — more donation-reliant than the typical peer (83% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 5 reported years ran a deficit.

57% 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 THE JANSEN DE VRIES SYNDROME FOUNDATION INC.
“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
57% of THE JANSEN DE VRIES SYNDROME FOUNDATION 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.

Funder states come from each funder’s own filing. $9k arriving through sponsors registered in 2 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.
