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.
Who funds it, year by year
2017 → 2023: the base narrowed from 4 funders to 3 funders, grant income fell $44k → $37k.
4 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 42% 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 HISTORIC BOSTON INCORPORATED’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
HISTORIC BOSTON INCORPORATED leans on a few funders — its largest provides 35% of grant income and the top three 75%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
77% 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 HISTORIC BOSTON INCORPORATED.
Largest funder’s share by year: 2017 37% · 2018 54% · 2019 68% · 2020 53% · 2021 56% · 2022 54% · 2023 53% — growing more concentrated.
“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.
How long its funders stay
22% of HISTORIC BOSTON INCORPORATED's funders are still giving 3 years after their first grant; 50% 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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
HISTORIC BOSTON INCORPORATED draws 69% of its grant income from funders outside Massachusetts, across 3 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $441k arriving through sponsors registered in 3 statesis 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.
