LocationLists: US Private Foundations, deductible = yes

122,998 organisations match (129,233 listings, 6,235 duplicates removed).
US Private Foundations was counted on the engine: its file is over the 80 MB a live read takes. The count is exact; filtered delivery still reads the file, so its rows are sold as the whole list, not by the row.

The file is the list as published. Add the essentials (county population, median household income and median age) or a group of area data to every row below.
Add more area data to every row (each link reloads this answer with those columns added, and the buy link then delivers them):

Left out:
- US Private Foundations: US Private Foundations was counted on the engine. Filtered delivery still reads the list's CSV, at most 80 MB per request, and this file is 108 MB, so these rows cannot be bought by the row yet; the whole list is sold as one file.
