The change over a term is the debt added. Source: U.S. Department of the Treasury, via FRED GFDEBTN (https://fred.stlouisfed.org/series/GFDEBTN), fetched Oct 19, 2026.

## Every term

Sorted by yearly change, fastest rise first. A term's first year mostly reflects the previous administration's policies, and Congress, the Federal Reserve and the world economy move these numbers too. Govargus describes; it does not score presidents.
