Subject Descriptor	Subject Notes
Gross domestic product, constant prices	Real GDP is expressed in billions of national currency units; the base year is country-specific.
Gross domestic product, constant prices	Annual percentages of constant price GDP are year-on-year changes; the base year is country-specific.
Gross domestic product, current prices	GDP is expressed in billions of national currency units.
Gross domestic product, current prices	Values are based upon GDP in national currency and the exchange rate projections provided by country economists for the group of other emerging market and developing countries. Exchanges rates for advanced economies are established in the WEO assumptions for each WEO exercise.
Gross domestic product, deflator	The GDP deflator is derived by dividing current price GDP by constant price GDP and is considered to be an alternate measure of inflation. Please note: Data are expressed in the base year of each country's national accounts.
Gross domestic product per capita, constant prices	GDP is expressed in constant national currency per person. Data are derived by dividing constant price GDP by total population.
Gross domestic product per capita, current prices	GDP is expressed in current national currency per person. Data are derived by dividing current price GDP by total population.
Gross domestic product per capita, current prices	GDP is expressed in current U.S. dollars per person. Data are derived by first converting GDP in national currency to U.S. dollars and then dividing it by total population.
Output gap in percent of potential GDP	Output gaps for advanced economies are calculated as actual GDP less potential GDP as a percent of potential GDP. Estimates of output gaps are subject to a significant margin of uncertainty. For a discussion of approaches to calculating potential output, see Paula R. De Masi, "IMF Estimates of Potential Output: Theory and Practice," in Staff Studies for the World Economic Outlook (Washington: IMF, December 1997), pp. 40-46.
Gross domestic product based on purchasing-power-parity (PPP) valuation of country GDP	These data form the basis for the country weights used to generate the World Economic Outlook country group composites for the domestic economy. Please note: The IMF is not a primary source for purchasing power parity (PPP) data. WEO weights have been created from primary sources and are used solely for purposes of generating country group composites. For primary source information, please refer to one of the following sources: the Organization for Economic Cooperation and Development, the World Bank, or the Penn World Tables. For further information see Box A2 in the April 2004 World Economic Outlook, Box 1.2 in the September 2003 World Economic Outlook for a discussion on the measurement of global growth and Box A.1 in the May 2000 World Economic Outlook for a summary of the revised PPP-based weights, and Annex IV of the May 1993 World Economic Outlook. See also Anne Marie Gulde and Marianne Schulze-Ghattas, "Purchasing Power Parity Based Weights for the World Economic Outlook," in Staff Studies for the World Economic Outlook (Washington: IMF, December 1993), pp. 106-23.

General government structural balance	The structural budget balance, or cyclically adjusted budget balance, is derived from a cyclically neutral budget model. [How to Measure the Fiscal Deficit?, Blejer and Cheasty, IMF, 1993, page 86-88]. This refers to the deficit or surplus which would prevail if the economy were at a ?normal? level. [?A Review of the Fiscal Impulse Measure,? Heller, Haas, and Mansur, IMF Occasional Paper, May 1986, page 36]
