What San Carlos Foundation does
Mission
International Development Programs: medical, prenatal, public health, education and social services delivered to poor persons in the USA, Central America, Mexico and developing countries.
As stated on its FY2026 Form 990.
Programs
The core function of the San Carlos Foundation is the support of about 12 volunteer doctors, lawyers, teachers, engineers, media trainers, counselors, and other professionals serving poor communities throughout the world, but mainly Central America. These professionals live in the communities where they work and build resources and capacity there by passing their skills and knowledge to others through social programs and training workshops.

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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $54k to $212k (+293%).
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 10 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.
Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 3 funders, grant income fell $52k → $17k.
3 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 31% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
SAN CARLOS FOUNDATION leans on a few funders — its largest provides 64% of grant income and the top three 95%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
95% 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 SAN CARLOS FOUNDATION.
Largest funder’s share by year: 2017 77% · 2018 100% · 2019 73% · 2020 66% · 2021 76% · 2022 57% · 2023 67% — 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.
Where its funders are
SAN CARLOS FOUNDATION draws 100% of its grant income from funders outside California, across 3 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $103k arriving through sponsors registered in 3 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.
