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.
Government-grant reliance: 2022 66% · 2023 72% · 2024 69%. Grants only. Government contracts and fees sit inside program revenue.
99% of LIGHTHOUSE SOCIAL SERVICE CENTERS’s revenue is contributions — more reliant on donations than three-quarters of its peers (7% for the typical peer).

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 LIGHTHOUSE SOCIAL SERVICE CENTERS.
