Isn't the one that is in Wikipedia? My son was confused too. And I helped him by going into And typed in search "gdp per capita formula" and gave me the next article. It's just the first part. So you can go and find what you're looking for. I don't know anything about this subject, but I hope it could help you. Nora. E.

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. GDP is defined as the total market value of all final goods and services produced within the country in a given period of time (usually a calendar year). It is also considered the sum of a value added at every stage of production (the intermediate stages) of all final goods and services produced within a country in a given period of time, and it is given a money value.

The most common approach to measuring and understanding GDP is the expenditure method:GDP = consumption + gross investment + government spending + (exports − imports), or,

GDP = C + I + G + (X-M).

"Gross" means depreciation of capital stock is not subtracted. If net investment (which is gross investment minus depreciation) is substituted for gross investment in the equation above, then the formula for net domestic product is obtained. Consumption and investment in this equation are expenditure on final goods and services. The exports-minus-imports part of the equation (often called net exports) adjusts this by subtracting the part of this expenditure not produced domestically (the imports), and adding back in domestic area (the exports).

Economists (since Keynes) have preferred to split the general consumption term into two parts; private consumption, and public sector (or government) spending. Two advantages of dividing total consumption this way in theoretical macroeconomics are:

  • Private consumption is a central concern of welfare economics. The private investment and trade portions of the economy are ultimately directed (in mainstream economic models) to increases in long-term private consumption.
  • If separated from endogenous private consumption, government consumption can be treated as exogenous,[citation needed] so that different government spending levels can be considered within a meaningful macroeconomic framework.


GDP is the total market value of all final goods and services produced within a given period by factors and production located within a county. While GDP per capita is the total market value of all final goods and services produced divided the total number of people in the country.Therefore, GDP per capita is :GDP/populations.
