What is GDP? | CNBC Explains

Summary

GDP, or Gross Domestic Product, is a key indicator of an economy's health, measuring the total value of all goods and services produced within a country. It's calculated by adding consumption, investment, government spending, and net exports. While it's a universal measure, GDP has limitations, such as not accounting for services, digital economy, economic equality, or unpaid work. Alternative measures for overall happiness and quality of life have been proposed but haven't gained traction.
