How many presidents have we had as of 2015?

Answer 1

As of 2015, 43 men have been U.S. Presidents. Because Grover Cleveland served non-consecutive terms (1885-1889 and 1893-1897), he is considered both the 22nd President and the 24th President, which is why Barack Obama is called the 44th President.

Answer 2

43 men have served as US president. Barack Obama, the current president, is often referred to as the 44th president because his is the 44th administration. Grover Cleveland had two non-consecutive terms and so is considered to have had two administrations.

Answer 3

Obama is the 44th President, but only the 43rd to hold the office. Grover Cleveland was both number 22 and 24.
