  • 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.
