Notes:               Note: Over GDP, 1 US dollar (US$) = 1 international dollar (I$).
                     Purchasing power parity is the number of currency units required to
                     buy goods equivalent to what can be bought with one unit of the base
                     country. We calculated our PPP over GDP. That is, our PPP is the
                     national currency value of GDP divided by the real value of GDP in
                     international dollars. International dollar has the same purchasing
                     power over total U.S. GDP as the U.S. dollar in a given base year.
