GDP is a measure of the total market value of all the goods and services produced in a country in a given period. It is used as the main indicator of a country’s economic health and is commonly used in international comparisons.
While GDP is an important measurement, it doesn’t tell us everything about a country’s economy. For example, it does not take into account any activity that is not part of the market, such as activities carried out by family members or volunteers for a charitable organisation. It also does not include any illegal activities such as buying or selling counterfeit goods, drugs or smuggled cigarettes. Additionally, GDP does not capture environmental damage or the depletion of non-renewable resources.
Economists use GDP to analyse the health of an economy, understand economic cycles and predict future growth. It is also a key input into public policy decisions, such as setting interest rates and managing budgets. The White House and Congress track GDP to assess the economy’s strength, while businesses use it to make decisions about jobs, expansion and investments. Central banks monitor GDP growth to set monetary policy.
There are several different ways of measuring GDP, each with their own strengths and weaknesses. Nominal GDP uses current prices and does not strip out inflation (the rate at which prices rise), so it can be misleading when comparing countries. Purchasing power parity (PPP) GDP takes into account differences in price levels between countries, so it allows more accurate cross-country comparisons.
