The BRICS (Brazil, Russia, India, China, South Africa) now have a bigger share of the world economy than the Euro area and the U.S. combined:

In 2019, BRICS combined GDP will surpass (using PPP-adjusted GDP) that of G7 economies, and in 2020, based on IMF forecasts, it will exceed the combined share of the world GDP for the US + EU27 economies.

Not a single BRICS economy is currently represented in G7.
