A country’s gross domestic product (GDP) is its monetary value of all the final goods and services produced within its borders in a specific period, such as a quarter or year. GDP includes the output of all market and nonmarket activities, such as government spending on defense or education. GDP is an important indicator of a nation’s economic health and the standard of living. It is used by politicians and policymakers to determine how fast the economy is growing, whether it needs a boost, or to predict future growth trends. GDP is also a common comparison between the economies of different countries.
The most common method for calculating GDP is the production approach, which adds up all the goods and services that come into existence in a country during one accounting period, such as a quarter or year. This includes the value of all wages paid to labor, the rental value of land, the return on capital in the form of interest and dividends, and corporate profits. The total is then multiplied by a country’s price level, which gives its nominal GDP.
This method excludes activities that take place outside of the formal economy, like under-the-table payments or black-market activity. It also does not include the work done by unpaid household help or volunteer efforts. In addition, GDP does not include the “intangible” assets of a country, such as its intellectual property, reputation and brand image. This is why GDP can be a controversial statistic.
