Gross world product

The gross world product (GWP), also known as gross world income (GWI),^[1] is the combined gross national income (previously, the "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).^{[nb 1]} According to the World Bank, the 2013 nominal GWP was approximately 75.59 trillion United States dollars.^[2] In 2017, according to the CIA's World Factbook, the GWP was around $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity (PPP).^[3] The per capita PPP GWP in 2017 was approximately 17,500 international dollars according to the World Factbook.^[3] According to the World Bank, the 2020 GWP in current dollars was approximately $84.705 trillion.^[4]

Historical and prehistorical estimates

In 1998, economic historian J. Bradford DeLong estimated the total GWP in 1990 U.S. dollars for the main years between one million years BCE and 2000 CE (shown in the table below).^[6]

Estimates from 2000 onwards are based on world GDP, PPP estimates in 2021 constant international dollars from the World Bank and subsequently converted to 1990 US$.^[7][8] "Billion" in the table below refers to the short scale usage of the term, where 1 billion = 1,000 million = 10⁹.
