Let's Break It Down - GDP

Introduction

When the news says the economy grew 2% last quarter, it is usually talking about GDP. Gross domestic product is the most common way to measure the size and health of an economy. The U.S. has the largest GDP in the world, at around $30 trillion a year. Understanding GDP helps you make sense of economic headlines.

What Is GDP?

GDP is the total value of all final goods and services produced within a country during a period of time. It includes everything from cars and haircuts to software and restaurant meals. Final goods are counted only once, so the steel in a car is not counted separately from the car itself. In the U.S., the Bureau of Economic Analysis releases GDP estimates every quarter.

How GDP Is Calculated

One common way to calculate GDP adds up four types of spending. Consumer spending is the biggest part, making up about two-thirds of U.S. GDP. Business investment, government spending, and net exports, which are exports minus imports, make up the rest. When these grow, GDP grows.

What GDP Misses

GDP does not measure everything that matters. It does not count unpaid work like caring for family members or volunteering. It does not show how income is shared, so a country can have high GDP but large inequality. It also does not account for pollution or happiness, which is why economists use other measures too.

Conclusion

GDP measures the total value of goods and services an economy produces. It is the main way to track economic growth and compare countries. But it does not capture everything, like well-being or inequality. Now you can read the economy's scoreboard!
