How about the ratio of community age (or exp(community age)) to national population? See this comment
Instead of trying to identify a founding date for every country’s EA community, maybe you could look at the year when it surpassed, say, 20 people in the survey. That data should be easier to find, and could also help address the issue of early false starts.
BTW I happened to see this comment which gives some interesting thoughts regarding why attrition in LMICs with small EA communities could be high. So my overall hypothesis at this point would be something like: the more EAs in your city, and the more EA funding that is available, the easier and more fun it gets to find out about EA and participate. If the circumstances are right, you can get exponential growth.
