To identify the years in which there was a budget deficit, we need to compare the revenue and expenditure for each year. A budget deficit occurs when the expenditure exceeds the revenue for a given year.
Let's go through the data year by year:
- 2001: Revenue = \[tex]$8 trillion, Expenditure = \$[/tex]6 trillion (No deficit, revenue is greater than expenditure)
- 2002: Revenue = \[tex]$5 trillion, Expenditure = \$[/tex]7 trillion (Deficit, as expenditure is greater than revenue)
- 2003: Revenue = \[tex]$8 trillion, Expenditure = \$[/tex]10 trillion (Deficit, as expenditure is greater than revenue)
- 2004: Revenue = \[tex]$9 trillion, Expenditure = \$[/tex]7 trillion (No deficit, revenue is greater than expenditure)
- 2005: Revenue = \[tex]$15 trillion, Expenditure = \$[/tex]18 trillion (Deficit, as expenditure is greater than revenue)
- 2006: Revenue = \[tex]$8 trillion, Expenditure = \$[/tex]10 trillion (Deficit, as expenditure is greater than revenue)
- 2007: Revenue = \[tex]$6 trillion, Expenditure = \$[/tex]4 trillion (No deficit, revenue is greater than expenditure)
- 2008: Revenue = \[tex]$2 trillion, Expenditure = \$[/tex]4 trillion (Deficit, as expenditure is greater than revenue)
- 2009: Revenue = \[tex]$7 trillion, Expenditure = \$[/tex]4 trillion (No deficit, revenue is greater than expenditure)
- 2010: Revenue = \[tex]$5 trillion, Expenditure = \$[/tex]9 trillion (Deficit, as expenditure is greater than revenue)
The years where the federal government had a budget deficit are:
[tex]\[ 2002, 2003, 2005, 2006, 2008, 2010 \][/tex]
