Federal budget

National debt by president (dollars)

Total public debt outstanding, including debt held by federal trust funds, in dollars of the day (not adjusted for inflation or the size of the economy; see federal debt as a share of GDP for that). The change over a term is the debt added.

By presidential term

National debt (dollars), term by term: every term lined up from inauguration on one chart.

Value at the last full period before inauguration and at the end of the term, with the yearly rate of change. The second column is the rate of change over the four years before the term: the trend they inherited. Remember the lag: a term's first year mostly reflects the previous one's policies.
