I am looking for any reasonable estimate of the total amount of funding controlled by the EA movement on a yearly basis. It is fine to operationalize this question in any reasonable way. I would be interested in any estimates people have as long as they are clear about their assumptions. I do want to be clear that I am not interested in 'how much total money goes to EA charities'. I am only interested in the total amount of funding that comes from EA sources. So please focus on the sources of funding, not just the targets. I am aware these numbers have changed year to year.
One source of information for this might be the 2019 EA Survey, which analyzed self-reported data for about 2500 EAs. Our prior analysis found that EAs in the survey reported total donations of $16.1M USD in 2018.
We didn't report raw income data, but it looks like the sum of self-reported annual income in our EA Survey sample is $116M USD.
Of course this is likely a large underestimate of the total financial firepower of EA ...for one, it ignores OpenPhil, which donates tens of millions of dollars a year and has the capacity to donate much more
...for two, there are probably another several tens of millions in annual donations by high net worth individuals who affiliate with EA somewhat but don't fill out the EA Survey, though if you keep looking into this eventually though you will get into difficult debates about who counts as EA or not.
