Both posts contain a more detailed breakdown of inputs, but in short:
80k seems to include every entry in the Open Phil grants database, whereas my sheet filters out items such as criminal justice reform that don’t map to the type of funding I’m attempting to track.
They also add a couple of ‘best guess’ terms to estimate unknown/undocumented funding sources; I do not.
Thanks! Small correction: Animal Welfare YTD is labeled as $53M, when it looks like the underlying data point is $17M (source and 2023 full-year projections here)
