What is GDP?
Gross domestic product (GDP) is a measure of a country's production using the sum of the final goods and services produced within its borders.
The OECD (Organisation for Economic Cooperation and Development) defines GDP as "an aggregate measure of production equal to the sum of the gross values added of all resident institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs)."((http://stats.oecd.org/glossary/detail.asp?ID=1163 Retrieved 12 December 2014)) First developed in 1934, GDP is used to measure the size of a country's economy by adding all private and public consumption, government spending, investments and exports.
GDP can be calculated as: GDP = C + G + I + NX
- C is consumer spending
- G is government spending
- I is investments
- NX is total exports, minus imports
Figured annually, GDP can help determine the efficacy of economic policy. As of 2013, the United States leads the world in GDP, with US$17.4 trillion. Global GDP is nearly US$75 trillion.
