The world’s largest economies, measured by gross domestic product (GDP) on a purchasing power parity (PPP) basis, are:
- United States
- China
- India
- Japan
- Germany
- Russia
- Brazil
- Indonesia
- United Kingdom
- France
This ranking can vary depending on the measure of economic size and the time period being considered. For example, using nominal GDP instead of PPP-adjusted GDP would result in slightly different rankings, and the rankings can change over time as economies grow or shrink.
