Are there estimates of how many EAs there are, and if so, what are those estimates? If not, how many EAs do we think there are?
I'm purposefully not defining what an EA is here; it's understandable that there would be different definitions with correspondingly different numbers.
Thanks, I was unfamiliar with their estimates for the proportion of the community they estimate.
"We estimate there are around 2315 highly engaged EAs and 6500 (90% CI: 4700-10,000) active EAs in the community overall."

That source also provides some other sources for estimates.
