via @JWMason1
from the interactive The Top Incomes Database —
you can select countries such as Argentina, China, Indonesia, Ireland
and you can select upper quantiles like the lower half of the top percent; the .5%–.1%; top .1%; the top 10%–5%; and so on
and you can get income controls, price level indices, number of tax units, number of adults — the things you need to divide by in order to make apples-to-apples comparisons
Wooo, data!
