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.
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. 0 of the last 8 reported years ran a deficit.
Who funds it, year by year
2019 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $1k → $54k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 65% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $3.1M from one payer (the payer shares this organization's board, largest DC Preparatory Academy). These are real filings, and they are not money DC PREP SUPPORT CORPORATION raised.
From the IRS filings of DC PREP SUPPORT CORPORATION’s funders (the co-funder graph). 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
DC PREP SUPPORT CORPORATION leans on a few funders — its largest provides 65% 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
65% 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 DC PREP SUPPORT CORPORATION.
Largest funder’s share by year: 2019 100% · 2020 88% · 2021 93% · 2022 100% · 2023 56% — 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
65% of DC PREP SUPPORT CORPORATION's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $33k that is directly attributable, 100% of it comes from funders outside Washington, D.C., across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $62k arriving through sponsors registered in 1 state 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.
