The table below gives recent percentage values for overall GWP growth from 2006 through 2020, as well as an estimate for 2021, according to the International Monetary Fund (IMF)'s World Economic Outlook database. Data is given in terms of constant year-on-year prices.7
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).8
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$.910 "Billion" in the table below refers to the short scale usage of the term, where 1 billion = 1,000 million = 109.
