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 2013, according to the CIA's World Factbook, the GWP totalled approximately US$87.25 trillion in terms of purchasing power parity (PPP), and around US$74.31 trillion in nominal terms. According to a separate estimate by the World Bank, the 2013 nominal GWP was approximately US$75.59 trillion. The per capita PPP GWP in 2014 was approximately US$16,100, according to the World Factbook.

The table below gives regional percentage values for overall GWP growth through 2014, as well as an estimate for 2015, according to the International Monetary Fund (IMF)'s World Economic Outlook database. Data is given in terms of constant year-on-year prices.
Historical and prehistorical estimates
In 1998, J. Bradford DeLong of the Department of Economics, U.C. Berkeley, estimated the total GWP in 1990 U.S. dollars for main years between one million years BCE and 2000 CE, as shown below. Nominal GWP estimates from 2005 onwards are also shown in contemporary U.S. dollars, according to estimates from the CIA World Factbook and the World Bank. "Billion" in the table below refers to the short scale usage of the term, where 1 billion = 1,000 million = 109.
