Regarding the Effective Altruism FB group member growth over time, I was able to piece together the following graph using archived snapshots and various other sources: https://i.imgur.com/Lejj0e1.png
The raw data (including sources for each data point) is available here. If anyone has more comprehensive data, please let me know.
Based on that, I estimate (linearly interpolate) the following member counts for January 1 of each year:
2014: ~1905
2015: ~4535
2016: ~8610
2017: ~11983
2018: ~14119
2019: ~16003
You have the actual data for 2018 and 2019. If you could share the correct counts for January 1 of those years it would be nice.
Wow, can you speak a bit more to how you recovered that data? That’s impressive.
From my actual stats, It looks like there were 14,398 users at the beginning of 2018 and 15,294 users at the beginning of 2019 which matches your equation pretty well.
I think that the 2018-12-05 datapoint is wrong because it came from a Quora answer which was later edited. I can’t prove this, but it seems likely because the rest of the datapoints are monotonically increasing.
Most of the other data came from FB itself (as documented in the ‘raw data’ link above), so it should be pretty solid.
