Historical Estimates of Total Taxable Resources for U.S. States, 1981-2000

Analysts have historically relied on slate personal income (SPI)as the benchmark for comparing state spending on public goodsand services and levels of state taxes. This occurs despitethe widely acknowledged shortcomings of using SPI as a measureof fiscal capacity, a state's ability to raise revenues fromits own sources. The U.S. Department of the Treasury has developeda more comprehensive measure of fiscal capacity, Total TaxableResources (TTR). Treasury has generated official estimates ofTTR since 1992 and has used two distinct methodologies to doso. The lack of a time series using a single methodology andcurrent estimates of income and production in the United Statesrepresents a significant barrier to the widespread use of TTRfor analytical purposes. This research note generates a timeseries (1981–2000) using Treasury's current methodologyfor estimating TTR and the latest estimates for income andproductionin the United States.
