Joe Biden will be the oldest US President to take oath

When Joseph R Biden Jr takes the oath of office on Wednesday, he will be the oldest person ever sworn in as president. Biden turned 78 in November.

During the campaign, Biden addressed his age head-on in interviews and presented himself as a “transition candidate” who would help nurture new Democratic talent.

Biden leveraged his age as a strength in the election and campaigned on two key messages, according to one historical expert.

“The first one: ‘I am not him,’ meaning Trump,” Jeffrey A. Engel, director of the Center for Presidential History at Southern Methodist University in Dallas, said on Wednesday. “The second was, ‘I am an adult and I will bring back normalcy and I will bring back a sense of decency and demonstrate maturity.’”

Donald J. Trump was 70 at his inauguration, making him then the oldest person to take the oath. Ronald Reagan was 69 at his first inauguration, in 1981.

Until Biden is sworn in on Wednesday, President Trump holds the record for the country’s oldest chief executive. He was 70 in January 2017, when he became the 45th president.

Before him, President Ronald Reagan was the oldest president. He was 69 in 1981 when he was inaugurated for his first term.

“I want you to know that also I will not make age an issue of this campaign,” he said. “I am not going to exploit for political purposes my opponent’s youth and inexperience.”

Reagan was 77 after his second term, the oldest president to leave office.

More than a century before him, William Henry Harrison held the distinction of being the oldest president at the time, when he was inaugurated in 1841 at age 68. Mr. Harrison, who had caught a cold that developed into pneumonia, died after 32 days in office. He became the first president to die in office and to date, has served the shortest tenure in U.S. presidential history.

At 96, Jimmy Carter is the oldest living former president.

Theodore Roosevelt was 42 when he assumed the presidency upon the assassination of William McKinley in 1901.

Many people may think John F. Kennedy, who was inaugurated in 1961 at age 43, was the youngest president. But that distinction belongs to Theodore Roosevelt, who was 42 in September 1901, when he assumed the presidency after the assassination of William McKinley.

Bill Clinton was 46 when he became president, in 1993.

Barack Obama took office in 2009 at age 47.

Other youthful presidents include Ulysses S. Grant, who was 46 when he took office in 1869; Bill Clinton, who was also 46 at his first inauguration, in 1993; and Barack Obama, who was 47 at his first inauguration in 2009. Three of the five youngest presidents were Democrats; Roosevelt and Grant were Republicans.

As dictated by the United States Constitution, the president must be a natural-born citizen of the United States, at least 35 years old and a resident of 14 years.

Joseph R. Biden Jr. will become president of the United States at noon on Jan. 20 in a scaled-back inauguration ceremony. While key elements will remain traditional, many events will be downsized and “reimagined” to better adapt the celebration to a nation battling the coronavirus. Biden will be sworn in by Chief Justice John G. Roberts Jr. on the Capitol’s West Front sometime before noon. The new president is then expected give his inaugural address and conduct a review of military troops, as is tradition. But instead of a traditional parade before cheering spectators along Pennsylvania Avenue as the new president, vice president and their families make their way to the White House over a mile away, there will be an official escort with representatives from every branch of the military for one city block.

The qualifications for president have not changed since George Washington first took office at 57 in 1789, according to the Library of Congress. He was sworn in on the balcony of Federal Hall on Wall Street in New York City, then the capital of the United States.

The average age of a president at inauguration: 55

Lyndon B. Johnson became president at 55 — the average age upon inauguration.

A 2011 JAMA article on presidential aging, which did not include Trump, observed that the average age of a U.S. president at inauguration was 55.1 years.

A similar ranking found that on average, presidents are sworn in at 55, according to, a project created by Bob Summers in 1996 as part of a graduate school project at the University of Michigan School of Information.

“Most of the people that become president usually need to build a body of work to prove to voters what they stand for and how they will get things done,” Summers said.

“That usually precludes much younger presidents,” he added. “And with the shorter life expectancies in the early days of the U.S., there were not as many people who would run as older candidates.”

How many father-son pairs have taken office?

George Bush was sworn in as president in 1989.

There have been two father-and-son sets of presidents, and both were similar in age when they each first took office.

John Adams was 61 when he became the second president, in 1797. His son John Quincy Adams was sworn in as the sixth president at 57 in 1825.
