A measure of a dollar's value with respect to some year. One may use a constant dollar analysis to account for inflation. For example, suppose one wishes to measure changes in the U.S. national debt. It would be most useful to use a constant dollar format, for example, by measuring the national debt for all years in the dollar's value in the year 2000. This eliminates inflation as a consideration when analyzing the national debt.
