The gross domestic product (GDP) or gross domestic income (GDI) is a basic measure of a country's economic performance and is the market value of all final goods and services made within the borders of a country in a year . It is a fundamental measurement of production and is very often positively correlated with the standard of living, [1] though its use as a stand-in for measuring progress in increasing the standard of living has come under increasing criticism and many countries are actively exploring alternative measures.[2] [3] GDP can be defined in three ways, all of which are conceptually identical. First, it is equal to the total expenditures for all final goods and services produced within the country in a stipulated period of time (usually a 365-day year). 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).[4][5]
