This visualization was created using the Monthly Statement of the Public Debt (MSPD) as the data source for federal debt of the United States. Historic gross domestic product (GDP) figures come from the Bureau of Economic Analysis (BEA). GDP for FY 2021 is based on the economic forecast for the 2022 Mid-Session Review, adjusted for the Bureau of Economic Analysis (BEA) revisions. Throughout this page, we use the gross domestic product for the Fiscal Year, not the Calendar Year, in order to facilitate an appropriate comparison.
