BALTIMORE & OHIO RAILROAD HISTORICAL SOCIETY INC

What Baltimore & Ohio Railroad Historical Society Inc does

The organization over time

Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 2021 to 2022, from $733k to $895k (+22%).

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 4 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

2020 → 2023: the base broadened from 1 funder to 2 funders, grant income rose $104 → $5k.

3 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 58% 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 BALTIMORE & OHIO RAILROAD HISTORICAL SOCIETY INC’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

BALTIMORE & OHIO RAILROAD HISTORICAL SOCIETY INC leans on a few funders — its largest provides 42% of grant income and the top three 99%; half comes from just 2 funders.

58% 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 BALTIMORE & OHIO RAILROAD HISTORICAL SOCIETY INC.

Largest funder’s share by year: 2020 100% · 2021 98% · 2022 98% · 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

58% of BALTIMORE & OHIO RAILROAD HISTORICAL SOCIETY INC'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 $26k that is directly attributable, 100% of it comes from funders outside Maryland, across 1 state.

Funder states come from each funder’s own filing. $35k 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.
