I think while this headcount is not a good metric how to allocate space in the EA handbook, it is a quite valuable overview in itself!
Just as a caveat, the numbers should not be directly compared to numbers from EA survey, as the later included also cause-prioritization, rationality, meta, politics & more.
(Using such cathegories, some organizations would end up in classified in different boxes)
