A table of all the U.S. Presidents arranged in order of when they served in office.

There are 47 names on the list of U.S. presidents, but how many presidents have there been?

The number of individuals that have been president is 45. The difference between the 47 names on the list and the correct value of 45 is due to the non-consecutive terms of Grover Cleveland and Donald Trump. Although listing all the presidents in order makes it look as if there have been 47 presidents, a simple count of the unique names will show only 45 men have served as President of the United States.
