List of Presidents of the United States by age

Last updated on 23 November 2017

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 presidential inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of 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 the president's date of birth and date of death, allowing for leap days; in parentheses, the same period is 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, their lifespan is calculated up to November 23, 2017. The second table includes 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

Age of presidental ascention.png
Age of presidents when assuming office approximately follows a bell curve (mean age marked by red line, c. 55.5 years)

The median age of accession to the presidency is roughly 55 years and 6 months, which is about how old Benjamin Harrison was at the time of his inauguration. The youngest person to assume the office was Theodore Roosevelt, who became president at the age of 42 years, 322 days, following William McKinley's assassination. The youngest person elected president was John F. Kennedy, who was inaugurated into office at the age of 43 years, 236 days. Assassinated three years into his term, he became the youngest at the time of leaving office (46 years, 177 days); the youngest person at the time of leaving office after serving a full four-year term was Theodore Roosevelt (50 years, 128 days). The oldest person at the time of entering office was Donald Trump, at the age of 70 years, 220 days; Ronald Reagan was the oldest person in office, at the age of 77 years, 349 days when his presidency ended in January 1989.

The oldest living U.S. president is George H. W. Bush, born June 12, 1924 (age 93 years, 164 days). The second oldest, Jimmy Carter, has the distinction of having the longest post-presidency in U.S. history, currently at 36 years, 307 days. The youngest living president is Barack Obama, born August 4, 1961 (age 56 years, 111 days).

The longest-lived president was Gerald Ford, who died at the age of 93 years, 165 days. He surpassed Ronald Reagan for this distinction on November 12, 2006, 44 days prior to his death. (Reagan had surpassed the 90 years, 247 days lifespan of the nation's second president, John Adams, on October 12, 2001.) The shortest-lived president to have died by natural causes (thereby excluding John F. Kennedy and James A. Garfield, who were both assassinated) was James K. Polk, who died at the age of 53 years, 225 days; only 103 days after leaving office.

Since 1797, when George Washington's service as president ended, there have been five periods in American history where the only living president was the incumbent president.

  1. John Adams, December 14, 1799 to March 4, 1801, between the death of George Washington, and the first inauguration of Thomas Jefferson
  2. Ulysses S. Grant, July 31, 1875 to March 4, 1877, between the death of Andrew Johnson and the inauguration of Rutherford B. Hayes
  3. Theodore Roosevelt, June 24, 1908 to March 4, 1909, between the death of Grover Cleveland and the inauguration of William Howard Taft
  4. Herbert Hoover, January 5, 1933 to March 4, 1933, between the death of Calvin Coolidge and the first inauguration of Franklin D. Roosevelt
  5. Richard Nixon, January 22, 1973 to August 9, 1974, between the death of Lyndon B. Johnson and the inauguration of Gerald Ford.

The greatest number of presidents—former presidents plus the incumbent—alive at any given time is six, which has happened four times.

  1. Including: Martin Van Buren, John Tyler, Millard Fillmore, Franklin Pierce, James Buchanan, and Abraham Lincoln; between March 4, 1861 (Abraham Lincoln's first inauguration) and January 18, 1862 (John Tyler's death)
  2. Including: Richard Nixon, Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush, and Bill Clinton; between January 20, 1993 (Bill Clinton's first inauguration) and April 22, 1994 (Richard Nixon's death)
  3. Including: Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush, Bill Clinton and George W. Bush; between January 20, 2001 (George W. Bush's first inauguration) and June 5, 2004 (Ronald Reagan's death)
  4. Including: Jimmy Carter, George H. W. Bush, Bill Clinton, George W. Bush, Barack Obama and Donald Trump; began on January 20, 2017 (Donald Trump's inauguration) and is ongoing.

Timeline of oldest living presidents

Of the 44 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 held this distinction for only 27 days.

On three occasions the oldest living president lost this distinction not by his death, but by the election of a president who was older. Theodore Roosevelt (born 1858) lost this distinction when William Taft (born 1857) was inaugurated, then four years later Taft lost it when Woodrow Wilson (born 1856) was inaugurated. More recently, Richard Nixon (born 1913) ceased being the oldest living president when Ronald Reagan (born 1911) 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 individual to acquire this distinction at the age of 90.

On seven occasions, the oldest living president has acquired this distinction during his term in office. In the cases of John Adams, Ulysses S. Grant, Theodore Roosevelt, Herbert Hoover and Richard Nixon, this happened at the same time as their becoming the only living president; in the cases of Andrew Jackson and Benjamin Harrison, the only other living president at the time was a younger predecessor (John Quincy Adams and Grover Cleveland respectively).
