The Group of Twenty
The G20 is the premier forum for international economic cooperation, bringing together 19 major economies plus the European Union and the African Union. Together they account for roughly 85% of global GDP, about two-thirds of the world’s population, and around three-quarters of international trade. This reference lists each member with its approximate nominal GDP, share of the world economy, population, and region, and lets you sort to compare them.
What the G20 is and how it works
The G20 began as a meeting of finance ministers and central bank governors in 1999, in response to the financial crises of the late 1990s. It was elevated to a heads-of-government summit in 2008 during the global financial crisis, when the smaller G8 was deemed insufficient for coordinating a global economic response.
The forum has no permanent secretariat. The presidency rotates annually among members, with the host country setting the agenda and convening the working groups. The 2023 summit was held in New Delhi under the Indian presidency; the African Union was admitted as a permanent member at that summit. Major agreements made at G20 summits — on tax reform, financial regulation, climate finance, and debt restructuring — carry significant practical weight even though the forum has no formal enforcement power.
The 19 countries plus two blocs
The individual country members are: Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom, and the United States.
The two bloc members are the European Union (representing 27 member states) and the African Union (representing 55 member states). Their figures in the table overlap with individual country members — France, Germany, and Italy are counted both as individual G20 members and within the EU bloc — so EU and AU GDP are shown for context and are not summed into a country total.
How to read the data
- GDP figures are nominal (not adjusted for purchasing power) in current US dollars, rounded to the nearest hundred billion for readability. They shift year to year with economic growth and exchange rate movements.
- The United States and China are consistently the two largest economies; the gap between them and the third-largest member is substantial.
- By population, India and China are far ahead of the others, while Australia, Saudi Arabia, and Argentina are much smaller than their GDP rank might suggest.
- Sorting by world GDP share shows why the forum matters: the top five members collectively represent a majority of global output.
