Guessing Populations

I decided to sit down and guess the current populations of (a) each US state and (b) each sovereign country. Given how often I work with this sort of data, I’d expect to be pretty good at this by now. I think I definitely did do pretty well, at least for the US. Below’s a map summary of results of where my guesses landed, although, of course, if you wish to try this yourself, you should probably not continue reading yet.


North Dakota turned out to be the state for which I most overestimated the population, at 131% of the actual population. I attribute this to overconsidering the effect of its recent boom. I’m not sure how to explain how I underestimated Connecticut’s population so substantially; it was the extreme in the other direction, at 61% of the actual population.


I was really, really shocked when I consulted the list of actual populations and found out Madagascar was over 6 times as populous as I guessed it would be. Kuwait was a mighty surprise too. The most populous country that I failed to guess the population to within 80% to 125% of the actual was Argentina.

Interestingly, my knowledge that Bahrain was ridiculously densely populated didn’t end up actually helping me, because I had no good mental estimator of how large Bahrain as an island was anyway.


Geographical Leaders in 8 Different Stats in Pokémon Go

This post consists of 16 charts, showing the top 12 countries and the top 12 cities in 8 Pokémon Go statistics: XP, Distance Walked, Pokémon Caught, Trainings, Battles Won, Berries Fed, Hours Defended, and Legendary Raids Won, as measured by the sum of the quantities of the top 25 players in the country or city, according to the last release of TL40 leaderboards. I used a convention that for a player whose statistic is “Not Disclosed”, I used the number for the next highest player that isn’t “Not Disclosed”, and if there isn’t such a next highest player with quantity disclosed, I used “0”.

Pokémon Go: Days 550 to 600

Shortly after reaching Level 40 in Pokémon Go on my 543rd day of playing, I decided to track 6 statistics on a one-update-a-day basis for 50 days. The raw cumulative data is available here, along with some Ingress stats. Here’s a chart of totals per approx-day over this period.


Notably, Pokémon Caught and Gym Berries Fed seem to be the most correlated statistics. This actually makes sense given that both are statistics correlated with ample consistent play (the latter due to berry limits).

Over this period of time, my Battles Won and Hours Defended stats tracked remarkably close to each other, cumulatively.


Note that this is actually extremely unusual: for most Level 40 trainers, hours defended vastly exceeds battles won. The ratio is nearly 1 for me mainly due to gym activity mostly being in the blisteringly-high-turnover grounds of the MIT area.
