Now, isolate those Indians who are living in India with an American standard of living (big house, car(s), frequent flyer), and I'm sure emissions will look a little bit more even. There are probably a lot more people living in poverty and not emitting much in India than in the U.S., it doesn't mean the situation per capita is better for these poor people in India that might lack electricity and plumbing (but on paper are living carbon neutral). Another case where the median might be better than the mean.

India's population is approximately 4.5 times that of USA, so the actual ratio is "one American is emitting 35 Indians worth of carbon emissions".

These numbers are already per capita, so the population difference is already accounted for.

So one USian emits as much as 9 Indians. Which is still a lot.
