With the oldest of the Baby Boomers turning 65 this year, the question of when one becomes a senior citizen is a topic of interest to a new generation.
At the age of 62, one can retire with social security benefits within the US, and is considered to be the age of a senior citizen by many organizations. However, the federal government has determined one who is 65 years of age or older is senior citizen.

So there are various opinions, but age 55 is about the youngest considered age.
