About This Statistic. The statistic shows global GDP (gross domestic product) from 2010 to 2014, with projections up until 2020. In 2015, global GDP amounted to about 74.2 trillion U.S. dollars.
Nominal GDP = â ptqt. where p refers to price, q is quantity, and t indicates the year in question (usually the current year). However, it can be misleading to do an apples-to-apples comparison of a GDP of $1 trillion in 2008 with a GDP of $200 billion in 1990. This is because of inflation.
