Why is per capita income calculated in dollars and not their currency by world bank?

Answer 2

Answer :

Per capita income of different countries is calculated in dollars and not in their own currencies because the dollar has been the strongest and stablest currency since the end of the 2nd World War and it becomes easy to compare the per capita incomes of various countries when these are converted into a common currency, i.e., US dollar ($).
