 Definition
The gross domestic product (GDP) or gross domestic income (GDI), is a basic measure of a country's economic performance, is the market value of all final goods and services made within the borders of a nation in a year. GDP can be defined in three ways.
First, it is equal to the total expenditures for all final goods and services produced within the country in a period of time.
Second, it is equal to the sum of the value added at every stage of production (the intermediate stages) by all the industries within a country, plus taxes less subsidies on products, in the period.
Third, it is equal to the sum of the income generated by production in the country in the period—that is, compensation of employees, taxes on production and imports less subsidies, and gross operating surplus (or profits).

GDP = private consumption + gross investment + government spending + (exports - imports).
