Claim: The G20 economies account for 85 % of the gross domestic product.
Evidence: Collectively , the G20 economies account for around 85 % of the gross world product -LRB- GWP -RRB- , 80 % of world trade -LRB- or , if excluding EU intra-trade , 75 % -RRB- , and two-thirds of the world population.
The gross world product -LRB- GWP -RRB- 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 -LRB- GDP -RRB-.
