The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 3% · 2021 55% · 2023 20%. Grants only. Government contracts and fees sit inside program revenue.
73% of ROB STEWART SHARKWATER FOUNDATION’s revenue is contributions — about as donation-reliant as the typical peer (87% for the typical peer).

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 ROB STEWART SHARKWATER FOUNDATION.
