the vertical line marks half of all grant income — 1 funder to its left
94% 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 Wiki Society of Washington DC Inc.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $100k 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.
