The Gross domestic product (GDP) or Gross domestic income (GDI) is one of the measures of national income and output for a given country economy. GDP is used as an indicator of standard of living in an economy, the rationale being that all citizens would benefit from their country's increased economic production.
Gross domestic product is calculated based on manufactured goods * average price. The GDP is country specific. On the economy page of every country, you can see daily GDP for the last 60 days, for each of the four industries: food, weapon, house and aircraft.
