CBO regularly publishes data to accompany some of its key reports. These data have been published in the Budget and Economic Outlook and Updates and in their associated supplemental material, except for that from the Long-Term Budget Outlook.
10-Year Budget Projections
Projections of spending and revenues by category and of deficits and debt held by the public.
Long-Term Budget Projections
Extensions of 10-year budget and economic projections for additional decades.
Historical Budget Data
Data on revenues, outlays, and the deficit or surplus from 1965 through the most recent year completed.
10-Year Trust Fund Projections
Trust fund balances projected in CBO’s baseline.
Revenue Projections, by Category
Projections of revenues by category, estimates of the effects of extending tax provisions scheduled to expire within ten years, and estimates of selected policy options affecting revenues. Starting in April 2018, additional information on revenue projection errors and a listing of legislation with significant impacts on federal revenues have been added to the data.
Spending Projections, by Budget Account
Projections of budget authority and outlays at the budget account level, organized by Treasury Identification Number.
Estimates of Automatic Stabilizers
Deficit or surplus with and without CBO’s estimate of automatic stabilizers, and related estimates of GDP and unemployment gaps.
Tax Parameters and Effective Marginal Tax Rates
Parameters used in CBO’s microsimulation tax model and effective marginal tax rates on labor and capital.
10-Year Economic Projections
Projections of output, prices, labor market measures, interest rates, and income. Beginning in January 2020, these files also include projections of potential GDP (the economy’s maximum sustainable output) and its underlying inputs.
Potential GDP and Underlying Inputs
Estimates, starting in 1949, of potential GDP (the economy’s maximum sustainable output) and its underlying inputs, including the natural rate of unemployment (the rate of unemployment arising from all sources except fluctuations in the overall demand for goods and services), various measures of the labor supply, capital services, and productivity.
Beginning in January 2020, projections of potential GDP and its underlying inputs are included in the supplemental files that contain CBO’s 10-year economic projections. Historical values of those series can be found in the supplemental files that contain historical data and economic projections.
