The data are of particular interest because (1) they afford a look at fiscal forecasts over six complete business cycles and several fiscal policy regimes, covering both peacetime and several wars, (2) the forecasts were precisely those presented to monetary policymakers, (3) they include frequently updated estimates of both actual and cyclically adjusted deficits, (4) unlike most other U.S. fiscal forecasts, they were neither partisan nor constrained by unrealistic assumptions about future fiscal policy, and (5) forecasts for other variables (GDP growth, inflation) from the same forecasters are known to compare favorably with most other available forecasts.
