NATIONAL SEPTEMBER 11 MEMORIAL & MUSEUM AT THE WORLD TRADE CENTER FOUNDATIONINC

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.

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 4% · 2018 0% · 2019 3%. Grants only. Government contracts and fees sit inside program revenue.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 3 reported years ran a deficit.

Who funds it, year by year

2017 → 2023: the base narrowed from 7 funders to 2 funders, grant income fell $115k → $40k.

6 of 21 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 7% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
