Data notes & caveats

The two columns use different valuation bases and should be compared as alternative measures of economic scale, not subtracted as though they were one currency.

Methodology

Nominal GDP and real PPP GDP are matched for sovereign nations in 2024 and ordered by nominal GDP. The two columns use different valuation bases and are presented as parallel measures of economic scale rather than a common-currency subtraction.

Source consistency notes

Every row uses the same 2024 period, sovereign-nation definition and matched World Bank indicators.
