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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $179k to $239k (+34%).
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: 2018 6% · 2022 11% · 2023 8% · 2024 17% · 2025 15%. Grants only. Government contracts and fees sit inside program revenue.
76% of DIMOND IMPROVEMENT ASSOCIATION’s revenue is contributions — more donation-reliant than the typical peer (62% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

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.
Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $-8500 → $15k.
2 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 64% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of DIMOND IMPROVEMENT ASSOCIATION’s funders (the co-funder graph). Top 4 of 5 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
DIMOND IMPROVEMENT ASSOCIATION leans on a few funders — its largest provides 56% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
99% 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 DIMOND IMPROVEMENT ASSOCIATION.
Largest funder’s share by year: 2020 100% · 2021 100% · 2022 100% · 2023 99% — broadly stable.
“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
98% of DIMOND IMPROVEMENT ASSOCIATION's grant income comes from California funders.
Funder states come from each funder’s own filing. $12k arriving through sponsors registered in 2 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.

DIMOND IMPROVEMENT ASSOCIATION holds deeper cash reserves than three-quarters of the 7,175 community improvement nonprofits its size.
