It's a numbers game: Biden, 82, and Trump, 78, move up as oldest living presidents after Jimmy Carter's death at 100
President Joe Biden is now the country's oldest living president with Sunday's death of 100-year-old President Jimmy Carter.
Despite Biden presently being in office, the 82-year-old was born before all the country's other living presidents: Bill Clinton, George W. Bush, Barack Obama and Donald Trump.
Trump, 78, is the second oldest living president.
He'll be sworn-in again on January 20, 2025.
Bush and Clinton are also 78 and were born in the months following Trump.
Bush was born on July 6, 1946 and Clinton was born on August 19, 1946, compared to Trump, who was born that year on Flag Day, June 14.
The youngest former president is Obama, who turned 63 on August 4.
Carter set a record as the longest-living president in American history - the only former president to turn 100 years old, which he did so on October 1.
President Joe Biden, 82, is the country's oldest living president, despite there being four men who were in office before him that are still alive after Sunday's death of 100-year-old Jimmy Carter
The four other living presidents are younger than Biden including former President Donald Trump (front row, left), George W. Bush (right, standing), Barack Obama (third from left) and Bill Clinton (third from right)
He outlived two presidents who served after him - President Ronald Reagan and President George H.W. Bush, the father of Bush 43.
Carter was sworn-in in 1977 at age 52.
Sixteen American presidents were younger than Carter at the time of their inaugurations - including Clinton and Obama decades later.
Reagan ousted Carter from the White House after just one term at the age of 69, turning 70 two weeks later.
He had to contend with concerns over his age when he ran for reelection in 1984.
During a debate against Democrat Walter Mondale, Reagan was asked if he was too old to be president.
Reagan would be 73 when he started a second term.
'I will not make age an issue of this campaign. I am not going to exploit, for political purposes, my opponent's youth and inexperience,' the Republican famously quipped.

Reagan lived to be 93, passing away on June 5, 2004.
Carter also outlived Bush 41 - Reagan's Republican vice president who was elected in 1988 after Reagan served two terms.
The senior Bush died at the age of 94 on November 30, 2018.
When Biden was sworn-in on January 20, 2021, he was 78 years and 61 days old - which was older than Reagan when Reagan left office.
And when Trump is sworn-in next month, he'll be 78 years and 220 days old - meaning he'll leave office even older than Biden in 2029.
