How many presidents are under the age 40?

Answer 1

Two U.S. Presidents turned 70 while in office, Dwight D. Eisenhower, three months before leaving office, and Ronald Reagan, three weeks after taking office.

Ronald Reagan must have been tough for his age. He was shot in the side and suffered a collapsed lung in an assassination attempt at the age of 70, after which he lived another 23 years!

Answer 2

If you are wanting to know how many Presidents were at least 70 years old upon initially assuming office then the answer is none. The oldest President to initially assume office was Ronald Reagan who was 69 years, 11 months and 14 days old when he assumed office on January 20, 1981. Eisenhower was the only other President who reached the age of 70 while still in office.

Answer 3

To date, no U.S. President has been under the age of 40, and only one Vice President was under 40 (John C. Breckinridge, the only incumbent Vice President to lose a Presidential election during the 19th century; he lost to Abraham Lincoln).

Answer 4

Ronald Reagan and Donald Trump were the only people over 70 years of age to win a U. S. Presidential election (Reagan was 73 when reelected in 1984, and Trump was 70 when elected in 2016). Trump is the only U. S. President to date who was over 70 when he began his presidency. Two others had passed the age of 70 while in office: Ronald Reagan and Dwight D. Eisenhower. Honorable mention goes to Andrew Jackson, who's second term ended less than two weeks before his 70th birthday.

Six former U. S. Presidents lived past the age of 90, including two who are still alive, and another five topped the age of 80. Altogether, of the 44 men who have been U. S. President to date, 24 (55%) passed 70 years of age. Here is a list of them in order by their ages at the times of their passings or their current age if still alive:
