List of Presidents of the United States by age

This is a list of Presidents of the United States by age. The first table charts the age of each United States President at the time of their presidential inauguration (first inauguration if they were elected to multiple and consecutive terms), at the time they left office, and at the time of their death. Each president's lifespan (age at death) is measured in two ways, to allow for the differing number of leap days that each experienced. The first figure is the number of days between date of birth and date of death, allowing for leap days; in parentheses the same period given in years and days, with the years being the number of whole years that the President lived, and the days being the number of days since the last birthday. Where the president is still living, lifespan is calculated up to September 29, 2016. The second table is of those presidents who had the distinction among their peers of being the oldest living president, and charts both when they became and ceased to be oldest living.

Overview[edit]

Age of presidents when assuming office approximately follows a bell curve (mean age marked by red line, c. 55 years)

The average age of accession is 54 years and 11 months, which falls between Herbert Hoover (22nd) and Lyndon B. Johnson (23rd). The youngest person to assume office was Theodore Roosevelt, who became president following William McKinley's assassination, at the age of 42 years, 322 days. The youngest president elected to office was John F Kennedy, who assumed office at the age of 43 years, 236 days, who was also the youngest to leave office when he was assassinated, at the age of 46 years, 177 days. The oldest president to assume office was Ronald Reagan, who was 69 years, 349 days old when he assumed office, and was also the oldest in office 77 years, 349 days, when he left office.

The oldest living president is George H. W. Bush, born June 12, 1924 (aged 92 years, 109 days). Jimmy Carter is the second-oldest, 111 days younger than Bush. Carter was born October 1, 1924 (aged 91 years, 364 days). The youngest living former president is Bill Clinton, born August 19, 1946 (aged 70 years, 41 days), followed by George W. Bush, 44 days older, born July 6, 1946 (aged 70 years, 85 days). The youngest living president is the incumbent, Barack Obama, born August 4, 1961 (aged 55 years, 56 days).

The longest-lived president was Gerald Ford, who died at the age of 93 years and 165 days. Ronald Reagan was the second longest-lived, 45 days fewer then Ford. The shortest-lived president was John F. Kennedy, who was assassinated at the age of 46 years and 177 days. The shortest-lived president to die a natural death was James K. Polk, who died of cholera at the age of 53 years and 225 days. The president with the longest retirement is Jimmy Carter, at 13,036 days. Carter achieved this record on September 8, 2012, surpassing Herbert Hoover, who died 11,553 days after leaving the presidency. The president with the shortest retirement was James K. Polk, who died 103 days after leaving the presidency.

The greatest number of presidents alive at any given time, including the incumbent, has been six. This has occurred three times. The first (including Martin Van Buren, John Tyler, Millard Fillmore, Franklin Pierce, James Buchanan and Abraham Lincoln) took place between Lincoln's inauguration on March 4, 1861 and Tyler's death on January 18, 1862. The second (including Richard Nixon, Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush and Bill Clinton) took place between Clinton's inauguration on January 20, 1993 and Nixon's death on April 22, 1994. The third (and longest, including Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush, Bill Clinton and George W. Bush) took place between G.W. Bush's inauguration on January 20, 2001 and Reagan's death on June 5, 2004.

Timeline of oldest living Presidents[edit]

Of the 43 persons who have served as president, 24 have become the oldest such individual of their time. Herbert Hoover became the oldest living president (while still president himself) when Calvin Coolidge died in January 1933, and retained this distinction until his death 31 years later. Lyndon B. Johnson became the oldest living president upon the death of Harry S. Truman in December 1972, but outlived him by only 27 days. On three occasions the oldest living president lost this distinction, not by his death, but due to the nation electing a president who was older. Theodore Roosevelt lost this distinction when William Taft was inaugurated, then four years later Taft lost it when Woodrow Wilson was inaugurated. More recently, Richard Nixon ceased being the oldest living president when Ronald Reagan was inaugurated. Furthermore, although Theodore Roosevelt was the youngest ever to become both the oldest living president (at age 50) and a former president (at age 51), he was the only living president or former president by the end of his term. Consequently, Taft was the oldest living president twice: first during his presidency (having succeeded the younger Roosevelt), and a second time after Wilson (his successor as president but an older man) died. Gerald Ford was the oldest to acquire this distinction (at age 90). Thomas Jefferson who was aged 83 years and 82 days old when he died, was the oldest president to die without also being the oldest president.
