Senior citizen is a common euphemism for an elderly person in both UK and US English, and it implies or means that the person is retired.This in turn usually implies or in fact means that the person is over the retirement age, which varies according to country. Synonyms include pensioner in UK English and retiree and senior in US English. Some dictionaries describe widespread usage of "senior citizen" for people over the age of 65. "Senior citizen" is replacing the term old-age pensioner traditionally used in UK English. The age which qualifies for senior citizen status varies widely. In governmental contexts it is usually associated with an age at which pensions or medical benefits for the elderly become available. In commercial contexts, where it may serve as a marketing device to attract customers, the age is often significantly lower.
