Definition of gross domestic product how it is measured?

Answer 1

The gross domestic product (GDP) or gross domestic income (GDI) is one of the measures of national income and output for a given country's economy. It is the total value of all final goods and services produced in a particular economy; the dollar value of all goods and services produced within a country's borders in a given year. 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). The most common approach to measuring and quantifying GDP is the expenditure method: GDP = consumption + gross investment + government spending + (exports − imports)
