  • 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.
  • 3-yr trend compares the latest filing year with the year two before it, so it needs grants on file for both. Most foundations file one year of grants, so most rows show a dash.
