G8 vs. G20

The G8 states derive their global claim to leadership from their by now shrinking portion of the global economy (approx. 45% in 2009; 65% in 2002) which is represented here as the light part of the northern hemisphere. the G20 countries, which incorporate all G8 members, represent 85% of the world economy (southern hemisphere).. the portion of the world economy each member country controls is shown in a box surrounding each country; black outlines are G8 countries, red outlines are G20 members. red dots indicate membership in either G8 or G20; countries not represented are joined by dotted lines.
