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.
0% of Save The Bay Action Fund’s revenue is contributions — more earned-revenue than three-quarters of its peers (92% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 6 of the last 8 reported years ran a deficit.

the vertical line marks half of all grant income — 1 funder to its left
100% 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 Save The Bay Action Fund.
Largest funder’s share by year: 2018 91% · 2019 100% — growing more concentrated.
