Global gross domestic product

Global gross domestic product amounts to almost 95 trillion U.S. dollars, with the United States making up more than one fifth of this figure alone. The 12 largest economies in the world includes all Group of Seven (G7) economies, as well as four of the BRICS economies, and South Korea. While the U.S. has consistently been the world's largest economy since the Second World War, it is estimated that it will be overtaken by China at some point this decade.

The gross domestic product of a country is calculated by taking spending and trade into account, to show how much the country can produce in a certain amount of time, usually per year. It represents the value of all goods and services produced during that year. Those countries considered to have emerging or developing economies account for almost 60 percent of global gross domestic product, while advanced economies make up over 40 percent.
