That way you could say the US is a small country because it only has ~1/4 of the population of China.

Just because a country has a smaller population it doesn't make it unsuitable to live or to compare economic data.

You're just being pedantic here.

There's a big difference between countries that above the US (top 18) on that list where there is a 10x to 100x difference. 1x (US) to 4x (China) does not a magnitude make.

Even given that I would concede that the U.S is a lot less populous country than China. Additionally, there's a lot of places where comparisons of stats are invalid because of that difference.
