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.
Source consistency notes
Same source, same year and same unit across all rows.
