PPP GNI (formerly PPP GNP) is gross national income (GNI)
converted to international dollars using purchasing power parity
rates. An international dollar has the same purchasing power
over GNI as a U.S. dollar has in the United States. Gross
national income is the sum of value added by all resident
producers plus any product taxes (less subsidies) not included
in the valuation of output plus net receipts of primary income
(compensation of employees and property income) from abroad.
