Step-by-step explanation:
Three periods when the U.S. budget deficit was relatively large are:
- The 1930s
- The 1980s
- The early 1990s
During these periods, the budget deficits were significant as a share of the GDP. Additionally, deficits were also large during World War II, the 2008-2009 recession, and the pandemic-induced recession in 2020.
