The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $1.3M to $2.4M (+88%).
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 66%. Grants only. Government contracts and fees sit inside program revenue.
87% of PORT GAMBLE S'KLALLAM FOUNDATION’s revenue is contributions — more donation-reliant than the typical peer (63% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 7 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.

From the IRS filings of PORT GAMBLE S'KLALLAM FOUNDATION’s funders (the co-funder graph). Top 25 of 26 funders by total. Association, not causation. 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.
How concentrated its funding is
PORT GAMBLE S'KLALLAM FOUNDATION has a broad base — no single funder exceeds 18% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
61% 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 PORT GAMBLE S'KLALLAM FOUNDATION.
Largest funder’s share by year: 2017 80% · 2018 50% · 2019 57% · 2020 34% · 2021 48% · 2022 30% · 2023 25% — 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.

33% of PORT GAMBLE S'KLALLAM FOUNDATION's funders are still giving 3 years after their first grant; 54% give in more than one year at all.
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.

Where its funders are

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $249k arriving through sponsors registered in 4 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.
