Data Sources: For a discussion of the sources of the government revenue data used here read How We Got the Data for usgovernmentrevenue.com.

Actual vs. Budgeted: Government revenue data in usgovernmentrevenue.com includes historical revenue and also future revenue in three categories: budgeted, estimated, and guesstimated. Records of recent revenue are more detailed than historical records of earlier times.

All federal receipts prior to 2017, state revenue prior to 2019 and local revenue prior to 2018 are actual. More recent spending, including future years out to 2022, are budgeted, estimated, or guesstimated.

Federal receipts for 1962 and after are based on federal data on receipts in the presidents budget. State and local receiptsboth for the United States as a whole and for individual statesfor 1992 and after are derived from spending, revenue, and debt data in the Census Bureaus census of state and local government finances.

Nationwide state and local revenue between 1971 and 1991 is obtained from Statistical Abstract of the United States. State and local revenue for individual states between 1957 and 1991 is obtained from an MS Access database at a US Census Bureau site: Govt_Finances.zip.

Federal revenue prior to 1962 and state and local revenue prior to 1971 is obtained from Bicentennial Edition: Historical Statistics of the United States, Colonial Times to 1970.
