Geography
Observed grants span 12 states in 2023 and include large national charities as well as local Illinois grantees; however Illinois is the single largest state recipient, receiving about one‑third of dollars.
Recipient Variety
In 2023 the foundation funded 74 distinct recipients across many program areas and made 130 grants, showing a broad and diverse recipient set despite some repeat funding to prior grantees.
New Applicants
The foundation signals an invitation/preselection model (application info notes preselected grants), but 17 new recipients appeared in 2023 (about 23%), so new entrants can access funding though unsolicited applicants are unlikely to use an open online application.
