Just to clarify, the EA Groups Survey is a joint project of Rethink Priorities and CEA (with all analysis done by Rethink Priorities). The post you link to is written by Rethink Priorities staff member Neil Dullaghan.
The writeup for the 2020 survey should be out within a month.
according to CEA’s 2020 annual review, they tracked 250 active groups via the EA Groups survey, compared to 176 at the end of 2019. So I think EA, in terms of number of active groups, has actually grown a lot in 2020 compared to 2015-2019.
This isn’t a safe inference, since it’s just comparing the size of the survey sample, and not necessarily the number of groups. That said, we do observe a similar pattern of growth in 2020 as in 2019.
Ah yes, thanks for clarifying and sorry for the omission! Looking forward to that writeup. Will there be an estimate of the number of groups including outside of the survey sample for that writeup David?
An “estimate of the number of groups including outside of the survey sample” wouldn’t quite make sense here, because I think we have good grounds to think that we (including CEA) know of the overwhelming majority of groups that exist(ed in 2020) and know that we captured >90% of the groups that exist.
For earlier years it’s a bit more speculative, what we can do there is something like what I mentioned in my reply to habryka comparing numbers across cohorts across year to get a sense of whether numbers actually seem to be growing or whether people from the 2019 survey are just dropping out.
