There are five living presidents including the current commander-in-chief, President Donald Trump, who is the oldest person ever elected president.

The other living Americans who have served as president are Barack Obama, George W. Bush, Bill Clinton, and Jimmy Carter. Their careers in the White House span more than four decades.

The record for the most living presidents and former presidents at one time is six. There were two such moments in modern history: 2017 and most of 2018, when the above presidents and George H.W. Bush were alive during the first two years of the Trump presidency, and between 2001 and 2004 when both Ronald Reagan and Gerald Ford were still alive during the George W. Bush presidency.

Of the five living presidents, only Clinton and Obama have the distinction of entering the office in their 40s. Carter and the younger Bush entered the White House in their 50s. Trump was 70 when he became president in January of 2017.

The last time a former president died was in November 2018, when the elder Bush died at age 94.

On March 21, 2019, Carter became the oldest living American president in history at 94 years and 172 days old. The elder Bush was 94 years and 171 days old when he died.
