World income inequalities

at the Global Rich List.

If you make $850/year, you are the median earner out of 6 billion people.

$1,840/year puts you in the top quintile

$26,000/year gets you in the top 10%

$48,000/year pushes you into the top 1%

$186,000/year ranks you in the top 0.1%

This is a good way to slice at things, but household income per household member might be better.
