Real GDP can be used to calculate the GDP growth rate, which indicates how much a country's production has increased (or decreased, if the growth rate is negative) compared to the previous year, typically expressed as percentage change. The economic growth can be expressed as real GDP growth rate or real GDP per capita growth rate.
Real GDP is an example of the distinction between real and nominal values in economics.Nominal gross domestic product is defined as the market value of all final goods produced in a geographical region, usually a country; this depends on the quantities of goods and services produced, and their respective prices.
A variety of measures of national income and output are used in economics to estimate total economic activity in a country or region, including gross domestic product (GDP), Gross national income (GNI), net national income (NNI), and adjusted national income (NNI adjusted for natural resource depletion – also called as NNI at factor cost).
How the health of the economy is measured, and why the GDP calculation matters.
Gross domestic product (GDP) is a measure of aggregate output. Nominal GDP in a particular period reflects prices that were current at the time, whereas real GDP compensates for inflation. Price indices and the U.S. National Income and Product Accounts are constructed from bundles of commodities and their respective prices.

The net exports is the part of GDP which is not consumed by domestic demand: N X = Y − ( C + I + G ) = Y − Domestic demand {\displaystyle NX=Y-(C+I+G)=Y-{\text{Domestic demand}}} If we transform the identity for net exports by subtracting consumption, investment and government spending we get the national accounts identity:
GDP (Gross Domestic Product) is the value of all goods and services produced within a country during one year. GDP measures flows rather than stocks (example: the public deficit is a flow, measured per unit of time, while the government debt is a stock, an accumulation). GDP can be expressed equivalently in terms of production or the types of ...
