The gross world product (GWP) is the combined gross national product 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 (GDP). In 2014, according to the CIA's World Factbook, the GWP totalled approximately US$107.5 trillion in terms of purchasing power parity (PPP), and around US$78.28 trillion in nominal terms. The per capita PPP GWP in 2014 was approximately US$16,100 according to the World Factbook. According to the World Bank, the 2013 nominal GWP was approximately US$75.59 trillion.
