Federal Budget & Deficit


The Federal Budget and Deficit

a review of the presidencies of the 20th century

Part 1: The century overview

We have heard many claims about the deficit. This page is provided to make data regarding the federal budget and the federal deficit more accessible.


It is easy to see that the greatest increases in both the budget and the deficit were W.W.I and W.W.II, and the only era that the deficit actually decreased noticeably was between W.W.I and the Great Depression.

As we look at the graphs below, recall there are two factors to the deficit: revenues received and money spent. Increasing deficits are caused either by a drop in revenues or an increase in expenditures.

Before proceeding to the patterns, we might just review the last 50 years. In this graph we look at per capita spending and deficit changes. We see that over the last 50 years, only one president, Clinton, left office with a record of fiscal conservatism. As of this writing, G. W. Bush set the record for fiscal liberalism by massively increasing both spending and deficits.

  • 1.0E+9 = 1 billion
  • 1.0E+10 = 10 billion
  • 1.0E+11 = 100 billion
  • 1.0E+12 = 1 trillion
  • 1.0E+13 = 10 trillion.

Part 2: The Presidencies

Most Americans believe that the president has primary power over both the federal budget and the economy as a whole. Both these assumptions are very doubtful, since congress sends the bills to the whitehouse, and the economy fluctuates with federal reserve policy, and external forces. None the less, we will review the budget by the presidencies.

For these graphs "tax hike" means a revenue increase resulting from any cause including improved economies and rate hikes.
The Wilson presidency was characterized by the creation of the Federal Reserve, the legitimizing of the Federal Income Tax, and WWI. During WWI, and then again WWII, we see the worst deficit in the 20th century, peaking at over 46% during the war. Since the spending increase is significantly larger than the revenue increase the deficit increases.

The left graphs show Federal revenues and spending.

The right graphs show the percent tax hike, percent spending hike and percent deficits for each year. At the end of each graph the term averages are shown.


  Coolidge & Hoover
The Coolidge presidency was the only 20th century era with decreasing deficit and decreasing taxes. Here, spending decreased faster than revenue so a surplus occurs.

Note: in a previous version of this page the deficit was calculated as, "What percent of revenues was spending?" Now we are using the more standard, "What percent of spending was revenues?"
Between the Great Depression and WWII, Roosevelt faced greater challenges than any other president. Between these two events the country nearly went bankrupt. None the less, one should ask, "When the people were impoverished and businesses were going under, wouldn't a 20% tax hike only make things more challenging?" Although taxes increased rapidly during this administration, spending increased much faster creating the largest enduring deficit ever.

During most of the Truman presidency decreased spending kept the budget balanced. Since revenues dropped slower and rose faster than spending a balanced budget occured.


  Kennedy - Johnson
The Johnson presidency saw the creation of the Great Society programs, the escalation in Vietnam, and the joining of the Social Security budget to the general budget. From this point forward, the social security surplus gets added into the general budget making the deficit appear smaller than it actually is. Here, revenue increases lag behind spending increases, so the deficit grows.

From Johnson until Clinton spending rises faster than revenues. So the deficit increases.
