The Congressional Budget Office (CBO) reports its "Long-Term Budget Outlook" annually, providing at least two scenarios for spending, revenue, deficits, and debt. The 2019 Outlook mainly covers the 30-year period through 2049. The "extended baseline scenario" assumes that the laws currently on the books will be implemented, for the most part. CBO reported in June 2019 that under this scenario: "Large budget deficits over the next 30 years are projected to drive federal debt held by the public to unprecedented levels—from 78 percent of gross domestic product (GDP) in 2019 to 144 percent by 2049.
