The G20 economies account for 85 % of the gross domestic product.
G20 . Collectively , the G20 economies account for around 85 % of the gross world product ( GWP ) , 80 % of world trade ( or , if excluding EU intra-trade , 75 % ) , and two-thirds of the world population . The gross world product ( GWP ) is the combined 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 ) .
