Gross Domestic Product
GDP measures the value of goods and services produced in a country.
About this topic
GDP is the total market value of all final goods and services produced within a country in a period, usually a year. It can be measured three ways: output, income and expenditure, where GDP = C + I + G + (X - M), meaning consumption, investment, government spending and net exports. Real GDP adjusts for inflation, while nominal GDP does not.
GDP matters because it shows the size of the economy and whether it is growing. Growth in real GDP usually means more jobs and higher incomes. GDP per person is used to compare living standards across countries. Only final goods count, to avoid double counting the flour inside bread.
Example: if households spend 700 billion, firms invest 200, the government spends 250, exports are 150 and imports 100, then GDP = 700 + 200 + 250 + (150 - 100) = 1,200 billion. If nominal GDP rises 6 percent but prices rise 4 percent, real growth is only about 2 percent. Second-hand sales and pure financial transfers are excluded.
Misconceptions: GDP does not measure happiness, leisure, environmental damage or unpaid work like housework and volunteering, and it ignores how evenly income is shared. Tip: use real GDP per capita when comparing countries or time periods.
