Year to year changes in the nominal level of output or income of an economy are affected by a combination of forces: real growth, price inflation, and exchange rates. Changes in any of the three can affect an economy's relative size and, therefore, its ranking in comparison to other economies. The Atlas method dampens variability caused by fluctuations in exchange rates, while the PPP method eliminates the effects of differences and changes in relative price levels, particularly non-tradables, and therefore provides a better overall measure of the real value of output produced by an economy compared to other economies. Per capita valuations can also be affected by revised population estimates. Rankings are based on all World Development Indicators economies. Economies with missing data are implictly included in the rankings at their approximate level so that the relative order of other economies remains consistent.
