The richest country in the world depends on the measure used:
- By total GDP (nominal GDP), the United States is the richest country in 2025, with a GDP of about $28.8 trillion and a GDP per capita of $84,648. It has the largest overall economic output driven by diverse sectors including finance, technology, and manufacturing.
- By GDP per capita (a measure of wealth per person), Luxembourg is the richest country in 2025, with a GDP per capita exceeding $141,000, due to its strong financial sector and small population.
- Other countries leading in GDP per capita include Singapore, Ireland, and Qatar, all recognized for their high standards of living and strong financial or energy sectors.
Thus, the United States stands as the richest country by total economic size, while Luxembourg tops the list by wealth per individual. Both perspectives define "richest" in different ways.
