  • Median grant and grant range come from each funder’s grant schedule; a dash means there is none to report. Community foundations and other charities list only grants over $5,000, so their figures run high.
  • “One grant” means a schedule with a single grant — no median, nothing to range over. “One amount” means several grants, all the same size.
  • A median grant larger than the grants paid is not a mistake: the grant schedule and the year’s total come from different parts of the tax filing, and a foundation can list a grant it approved in a year it paid out less.
