Reading this series over a presidential term

The ratio falls when the economy grows faster than the debt, which can happen through growth, through inflation, or through a shrinking deficit. A term can cut this ratio without cutting a dollar of borrowing.

It uses gross debt, including what the government owes its own trust funds; a ratio built on debt held by the public would be lower and would move differently. Both numerator and denominator are revised.

These are the observed values over the window above, and nothing more. This site does not say which direction is better, and none of this is a claim that Lyndon B. Johnson caused the number to move.
