$11,571 spent4% of program spendingBell schoolhouse: bell school ca. 1841 was so named because of a bell in its tower. The original name of the school was sandy hill academy. In the early 1900s bell school was renamed alumni hall with a library on the second floor and a community hall on the first floor. During the westport fair and cattle show held at the head from 1911-1930, bell school was used as an agricultural hall for fair exhibits. The westport fair and cattle show was the forerunner of the present westport agricultural fair. Presently the bell school is the home of the westport historical society. This property was deeded to the organization subject to covenants to use the property for antiquarian and/or historical purposes and to maintain the property and its belfry within specific dimensions. Bell school cannot be sold but must be transferred to another antiquarian or historical society,without charge.

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 2018 to 2019, from $665k to $949k (+43%).
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: 2017 1% · 2020 40% · 2021 40% · 2022 5%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 8 funders, grant income rose $4k → $185k.
3 of 18 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 24% 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 WESTPORT 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.

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.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $97k 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.
