Late reply here but I think a potential difference is that the global health and development jobs attract significantly more non-EA applicants than the AI and pandemics jobs.  

So if we are talking about EA shifting away from global health, maybe it is more about the number of EA-aligned individuals applying to global health and development jobs vs longtermist jobs.

I would imagine if you look at number of jobs in EA that focus on longtermism vs Global health & Development, the picture would be more skewed towards longtermism relatively to funding.

Is the "How I spent my time" SE meant to only add up to 95%?
