92% 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 HERITAGE MUSEUM OF ROBERTS COUNTY.
Largest funder’s share by year: 2017 88% · 2018 88% · 2019 89% · 2020 94% · 2021 96% · 2022 94% · 2023 93% — growing more concentrated.
