Not every foundation here is a Boston foundation. The city is the mailing address on the foundation’s tax filing, and when a bank or a law firm runs the trust that is the bank’s address, not the place it gives to. Check where a foundation gives before you write.

  • Median grant and grant range come from the 990-PF grant schedule; a dash means there is none to report.
  • “One grant” means a schedule with a single grant — no median, nothing to range over. “One amount” means several grants, all the same size.
