I'd like to see this as a percentage increase of the population. Basically, it's just a list of the most populated countries in the world with a few exceptions. But if this was percentage of population, it would be much more challenging. Also, technically wouldn't South Sudan be in the 2010s since it gained independence in 2011? That means that it went from 0 population to over 11 million? :-)

Read the second caveat - I assume that also means it takes the current southern Sudan's population as it was in 2010, and it counted the northern half for every other decade.

With a population well under 2 million, it's not making it on the list regardless of the rules.

As Buck2017 added, it is more or less a list of the most populated countries. It would be better if it had the % of each decade.

If this was measured in terms of the number of Americans who threaten to move to Canada but never actually do, yeah, they'd be in the top 3 of every decade.

I met a guy in China who left the United States because Obama was elected. Not really sure how moving to an ostensibly communist country with far fewer freedoms than we have ameliorated any of his concerns, but I have to admire him for being the only American I have ever met who made good on a promise to leave if the wrong candidate was elected. Or maybe he was just full of it and moved for a different. Still though.

+jmellor he probably moved because here in China government market caps mean your dollars are worth at least three times their worth in the USA, and any American that speaks English can get a job as a teacher.

Makes as much sense as getting mad at the NSA for not respecting people's private data, illegally stealing tons of classified information, and then giving that data to the Russians and the Chinese without even reviewing it yourself, I guess?
