Have US deficits been cut in half since Obama came into office?

Recently in this interview with CNBC (at 00:00:39), President Obama said "Deficits are coming down; they have been cut in half since I came into office."

Is this true? What statistic is he referring to? Is this more or less a red herring, referring to the extraordinarily large deficits that were temporarily run for things like TARP, etc.?

The Congressional Budget Office defines the federal budget deficits (pdf) as when spending exceeds revenues for the fiscal year (October 1st through September 30th) so it is reasonable to assume that this what President Obama is referring to when he maid that claim. Additionally, since the deficit is defined solely on the basis of the receipts vs. outlays, programs such as the Troubled Asset Relief Program (TARP) are included in the official figures.

According to the Monthly Treasury Statement for September 2013 (pdf) there was a \$680 billion deficit for Fiscal Year 2013 through September 30, 2013. According to the Office of Management and Budget Historical Tables, the following are the total receipts, outlays, and deficits for 2008 through 2012 (source, xls) in nominal dollars:

```Year    Receipts    Outlays     Surplus or Deficit (-)
2008    2,523,991   2,982,544   -458,553
2009    2,104,989   3,517,677   -1,412,688
2010    2,162,706   3,457,079   -1,294,373
2011    2,303,466   3,603,059   -1,299,593
2012    2,450,164   3,537,127   -1,086,963
```

Using the Fiscal Year 2009 deficit of \$1,412 billion that means that as of August 2013 the Fiscal Year 2013 reduction of \$680 billion is accurate on the hard numbers and is about a 52% reduction.

If we adjust these values for inflation by using an inflation calculator then we find that \$680 billion in 2013 dollars is the same about \$623 billion in 2009 dollars. This represents about a 56% reduction in the deficit when compared to it in 2009 which means that the statement is also accurate using inflation adjusted figures.

Another way of looking at the deficit is as a percentage of the gross domestic product (GDP) which has also been done by President Obama and was examined by FactCheck.org,

In fact, although the White House didn’t cite it, the newly released mid-year projection from the White House Office of Management and Budget for the 2013 fiscal year shows that due to rising revenues, the 2013 deficit is now projected to be \$759 billion — \$214 billion lower than the \$973 billion deficit projected in the original budget. As a percentage of GDP, the 2013 deficit is now projected to equal 4.7 percent. The nonpartisan Congressional Budget Office projects an even lower 2013 deficit of \$642 billion, or 4 percent of GDP. That’s still above the level in 2008 (or any year since 1992), but it’s substantially lower than 2009. (Even if those projections pan out, however, Obama’s talking point wouldn’t be correct.)

where the deficit as a percentage of the GDP was -10.10% on December 31, 2009 which would make this claim accurate but still dependent upon the final Fiscal Year 2013 data.

• The deficit in 2009 doesn't appear to be drastically higher than in the years that follow. I assume that the majority of the difference between 2008 levels is due to lower government receipts, rather than a result of TARP and the stimulus? Commented Oct 3, 2013 at 13:08
• Do you know if the table you exhibit is in inflation adjusted dollars or in raw dollars? Commented Oct 3, 2013 at 13:55
• I think a 47% reduction qualifies as "cut in half". I would rate the statement as true, or at least "mostly true", but certainly not "not accurate"

• In 2013 dollars, the 2009 deficit was roughly 1,540,000, so the current deficit is less than half that. Commented Oct 4, 2013 at 4:04
