About this data
The DEC alternative conversion factor is the underlying annual exchange rate (the price of one country’s currency in relation to another country's currency) used for the World Bank Atlas method. As a rule, it is the official exchange rate reported in the IMF's International Financial Statistics. Exceptions arise where further refinements are made by World Bank staff. It is expressed in local currency units per U.S. dollar.
