Gross world product
The gross world product is the combined gross national income of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product. According to the World Bank, the 2013 nominal GWP was approximately US$ 75.59 trillion. In 2017, according to the CIA's World Factbook, the GWP was around US $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity. The per capita PPP GWP in 2017 was approximately Int$17,500 according to the World Factbook.
