Evidence: Supports the 2025 gross government debt-to-GDP values and ranking.

Data notes & caveats

Values are gross general government debt, not net debt, so they do not account for government financial assets. The 2025 figures are the latest available estimates rather than final audited outturns.

Methodology

Nations are ranked by general government gross debt as a share of GDP for 2025, using a single IMF World Economic Outlook vintage so the values are comparable.
