A list of countries by GDP ranks national economies by gross domestic product, usually in nominal terms or adjusted for purchasing power parity (PPP). Such lists are commonly used to compare the size of economies, with rankings varying by source, year, and measurement method.

Measurement methods

GDP rankings may be based on nominal GDP, which uses market exchange rates, or PPP GDP, which adjusts for cost-of-living differences. Because the methods differ, countries can appear in different orders depending on the dataset.

Major ranking sources

The IMF, World Bank, and United Nations are among the most widely used sources for country GDP comparisons. Their estimates may differ slightly because of methodology, reference year, and data revisions.

Use in economics

These rankings are used to compare the relative size of national economies and to track changes over time. They are often cited in business, journalism, and policy analysis.
