This is a list of United States Presidents by age. This table can be sorted to display United States Presidents by name, order of office, date of birth, age at inauguration, length of retirement, or lifespan. Age at inauguration is determined by the day a president assumed office, not the day of the election.

Two measures of longevity are given; this is to allow for the differing number of leap days occurring within the life of each President. 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 the President lived, and the days being the remaining number of days after his last birthday. Where the president in question is still living, the longevity is calculated up to October 14, 2012.

Overview

Age of presidents when assuming office approximately follows a bell curve (mean age marked by red line)

The median age of accession is roughly 54 years and 11 months, which falls between Herbert Hoover (22nd youngest) and Lyndon B. Johnson (23rd). The youngest person to assume office was Theodore Roosevelt (age 42), who became president following William McKinley's assassination. The youngest president elected to office was John F. Kennedy (age 43 years, 236 days). The oldest president to assume office was Ronald Reagan (age 69 years, 349 days).

The oldest living former president is George H. W. Bush, born June 12, 1924 (aged 700188000000000000088 years, 7002124000000000000124 days). Jimmy Carter is the second-oldest, only 111 days younger than Bush. Carter was born October 1, 1924 (aged 700188000000000000088 years, 700113000000000000013 days). The youngest living former president is Bill Clinton, born August 19, 1946 (aged 700166000000000000066 years, 700156000000000000056 days), closely followed by George W. Bush, only 44 days older, born July 6, 1946 (aged 700166000000000000066 years, 7002100000000000000100 days). The youngest living president is the incumbent, Barack Obama, born August 4, 1961 (aged 700151000000000000051 years, 700171000000000000071 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, only 45 days short of Ford. The oldest living president, George H. W. Bush, will tie Reagan if he lives to October 10, 2017 and tie Ford if he lives to November 24, 2017. The second oldest living president, Jimmy Carter, will tie Reagan if he lives to January 29, 2018 and tie Ford if he lives to March 15, 2018. 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 at the age of 53 years and 225 days. Since the presidency began, the longest period of time without the death of a president has been 26 years, 21 days between the death of George Washington and the same-day deaths of John Adams and Thomas Jefferson.

The president with the longest retirement is Jimmy Carter, at 11,590 days. Carter achieved this record on September 8, 2012. The president with the second-longest retirement is Herbert Hoover, who died 11,553 days after leaving the presidency. Hoover held the record for more than 54 years, from July 5, 1958, when he surpassed John Adams, until September 8, 2012, when Carter surpassed Hoover. The president with the shortest retirement was James K. Polk, who died 103 days after leaving the presidency.

Barack Obama became the fifth-youngest person inaugurated as president, at 47 years and 169 days old. Theodore Roosevelt, John F. Kennedy, Bill Clinton, and Ulysses S. Grant, in that order, were younger than Obama when they took the oath of office; Grover Cleveland was about six months older (see table below).

Oldest Living United States Presidents

There is always an oldest living U.S. President. Not all presidents live to become the oldest of their time; so far approximately 60% have done so. Herbert Hoover became the oldest living president when Calvin Coolidge died in 1933 (when Hoover was still president) and kept this title until his death, for a record of more than 31 years. Lyndon B. Johnson got the title after the death of Harry S. Truman, but he outlived Truman for only 27 days. A special case is William Howard Taft, who held the title twice: the first period was his presidency (i.e. he replaced someone younger than himself), and the second was when his successor as president, Woodrow Wilson, died.
