Claim: Taiwan is a place.

This article includes a list of countries by their forecasted estimated gross domestic product -LRB- PPP -RRB- . Countries are sorted by GDP PPP forecasted estimates from financial and statistical institutions in the limited period January-April 2017 , which are calculated at market or government official exchange rates . The GDP dollar -LRB- INT$ -RRB- data given on this page are derived from purchasing power parity -LRB- PPP -RRB- calculations .   Comparisons using PPP are arguably more useful than nominal when assessing a nation 's domestic market because PPP takes into account the relative cost of local goods , services and inflation rates of the country , rather than using international market exchange rates which may distort the real differences in per capita income . It is however limited when measuring financial flows between countries . PPP is often used to gauge global poverty thresholds and is used by the United Nations in constructing the human development index . These surveys such as the International Comparison Program include both tradable and non-tradable goods in an attempt to estimate a representative basket of all goods .   The first table includes estimation for the year 2017 , for all current 191 International Monetary Fund -LRB- IMF -RRB- members , as well as Hong Kong and Taiwan -LRB- the official list uses `` Taiwan , Province of China '' -RRB- . Data are in millions of international dollars and were calculated by the IMF . Figures were published in April 2017 . The second table includes data mostly for the year 2015 for 180 of the 193 current United Nations member states , as well as the two Chinese Special Administrative Regions -LRB- Hong Kong and Macau -RRB- . Data are in billions of international dollars and were compiled by the World Bank . The third table is a tabulation of the CIA World Factbook Gross Domestic Product -LRB- GDP -RRB- -LRB- Purchasing Power Parity -RRB- data update of 2016 . The data for GDP at purchasing power parity have also been rebased using the new International Comparison Program price surveys and extrapolated to 2007 .
