Wikimedia list article
This is a list of presidents of the United States by age. The first table charts the age of each president of the United States at the time of their inauguration (first inauguration if elected to multiple and consecutive terms), upon leaving office, and at the time of death. Presidents who are still living have their lifespans and post-presidency timespans calculated through September 20, 2026.
Age of presidents
Article Two of the United States Constitution provides that U.S. presidents must be at least 35 years old at the time they take office. The median age at inauguration of incoming U.S. presidents is 55 years. The youngest person to become U.S. president was Theodore Roosevelt at age 42, who succeeded to the office after the assassination of William McKinley. The oldest person to be inaugurated president is Donald Trump, at age 78 years, 7 months, for his nonconsecutive second term.
John F. Kennedy was the youngest person elected as president, at age 43; assassinated at age 46, he was also the youngest president at the end of his tenure, and his lifespan was the shortest of any president. The oldest president at the end of his tenure is Joe Biden at age 82 years, 2 months. Jimmy Carter had the longest lifespan of any president, becoming the first president to reach the age of 100.
This brief starts where responsible research should: with the source description of “List of presidents of the United States by age” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q3099823. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
