How does real GDP control the overall economic output and performance of a country?

Real GDP, or Gross Domestic Product adjusted for inflation, is a key measure of a country's economic output. It reflects the total value of all goods and services produced within a country's borders. By tracking changes in real GDP over time, policymakers can assess the overall economic performance of a country. A growing real GDP indicates a healthy economy with increased production and consumption, while a declining real GDP may signal economic contraction. Policymakers can use this information to make decisions on fiscal and monetary policies to stimulate economic growth or stabilize the economy.
