Average Age of Presidents. The majority of the presidents were between the ages of 50 and 59 when they were elected into office. The youngest elected president was John F. Kennedy at age 43. The oldest elected president was Ronald Reagan at age 69.
Age is obviously no guarantee of good judgment for a politician â see New Yorkers Anthony Weiner (48) and Eliott Spitzer (54). But the idea that age brings wisdom and maturity is what the Founding Fathers had in mind when they spelled out in the Constitution that a president of the USA must be at least 35.
