How Many US Presidents Were First-Born Sons?

The majority of US presidents have been either first-born children or first-born sons. Out of the first 44 presidents of the United States, 24 were first-born children or first-born sons, including Thomas Jefferson, Abraham Lincoln and Theodore Roosevelt. No US president has been an only child. It is thought that the reason why the majority of US presidents have been first-born children or first-born sons might be because oldest children tend to be given more responsibilities, such as babysitting their siblings, which might translate into the older children becoming comfortable with being leaders. First-born children might also have more confidence because they do not have to share attention with others as much during the first years of their lives, and their milestones are often more celebrated because they are the first in the family.

Frequently Asked Questions

How many US Presidents were first-born sons?

As of the knowledge cutoff in 2023, a significant number of U.S. Presidents were first-born sons in their families. While the exact number can fluctuate with new administrations, historically, more than half of the Presidents have been first-borns. This trend is often attributed to the leadership qualities and responsibilities that are typically associated with first-born children.

Does being a first-born son have any correlation with becoming a US President?

While there is no direct causation between being a first-born son and becoming a U.S. President, there is an interesting correlation. First-borns are often thought to have leadership qualities instilled through family dynamics. However, it's important to note that many factors contribute to one's path to the presidency, including personal ambition, political circumstances, and societal factors.

What are some notable US Presidents who were first-born sons?

Notable U.S. Presidents who were first-born sons include George Washington, Thomas Jefferson, and Theodore Roosevelt. These Presidents are often celebrated for their leadership and contributions to the country's development. Their status as first-borns is sometimes highlighted in discussions about their early development of leadership skills.

Are there any trends in birth order among US Presidents?

While the trend of U.S. Presidents being first-born sons is notable, there is also a variety of birth orders represented among Presidents. Some were middle children, like James Madison, while others, like Franklin D. Roosevelt, were the last born. The diversity in birth order suggests that while first-borns are common, leadership can emerge from any birth position.

How does the birth order of US Presidents compare to the general population?

The prevalence of first-born sons among U.S. Presidents is higher than in the general population, where first-borns make up a smaller percentage. This overrepresentation might suggest that the qualities and experiences of first-borns—such as being role models for siblings or having more parental attention—could play a role in their propensity for leadership positions like the presidency.

Any more info on firstborns? This is a tad bit of good info, but not enough to help with my report. Thanks anyway.


This is excellent information. Parents should encourage their children to become all that God intended for them to be. I am quite sure that God can help all children become someone important. I believe that all jobs are important, no matter what they do.
