Updated: Jun 26

Age for Current & Past US Presidents VS World Leaders and Lifespan

The 2024 presidential race is heating up, with Donald Trump and Joe Biden as the key contenders. Both have held the highest office in the United States, but how do they compare to past Presidents and current world leaders in age? LandGate provided visualizations for age vs the average lifespan for historical and contemporary figures, but the most interesting thing is that either candidate, if re-elected will be given the title of the oldest U.S. president at inauguration.

The Age Factor 

One of the most discussed aspects of both Biden and Trump's candidacies is their age and there is currently no age limit to serve as President in the U.S.

Here's a detailed look:

How old is Joe Biden?

  • Current Age: 81 (born November 20, 1942)

  • Oldest U.S. President: Biden became the oldest American president when he assumed office at the age of 78 years and two months. If re-elected Biden would be 82 at the time of inauguration.

  • Global Ranking: According to Pew Research Center, Biden is the ninth oldest national leader in the world.

How old is Donald Trump?

  • Current Age: 78 (born June 14, 1946)

  • Oldest Presidents List: If re-elected, Trump would overtake Biden as the oldest person to assume the U.S. presidency with an age of 78 years and 6 months at the time of inauguration.

  • Global Ranking: Trump would be amongst the nine oldest national leaders in the world if re-elected according to Pew Research Center.

Age Vs. Average Lifespan for U.S. Presidents

While age provides an interesting metric, it's also insightful to consider how that relates to the average lifespan of the served term. Since the average lifetime has increased over the decades, we can compare the average lifespans of past U.S. presidents with their time period of average lifespan. Doing this we can create a figurative visual for each. For example, according to the Centers for Disease Control and Prevention (CDC), the average lifespan of a U.S. citizen is approximately 77 years as of 2021. However, in Andrew Jackson's time period of his presidential term, the estimated average lifespan was more like 62 years.

Oldest Presidents Ages Compared with Average Lifespan

According to that comparison, one can see that relative to the average life span, all of the oldest U.S. presidents were serving at a very ripe age even for their time period. Leaders inherently receive better care, have more power, and will therefore live longer than an average citizen. When comparing US leaders to world leaders, U.S. contenders are significantly less elderly.

Conclusion of the Presidential Candidates

Trump and Biden, both in their later years, stand out as some of the oldest presidential candidates in U.S. history. Either candidate will take or keep the title as the oldest President at the time of inauguration if re-elected. Their age brings experience but also raises questions about energy and longevity. Comparing them to past U.S. presidents and current world leaders provides valuable context for understanding their potential impacts if elected.
