Senior citizen is a common euphemism for an old person used in American English, and sometimes in British English. It implies or means that the person being referred to 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 old age pensioner or pensioner in British English, and retiree and senior in American English. Some dictionaries describe widespread usage of "senior citizen" for people over the age of 65. When defined in an official context, senior citizen is often used for legal or policy-related reasons in determining who is eligible for certain benefits available to the age group. It is used in general usage instead of traditional terms such as old person, old-age pensioner, or elderly as a courtesy and to signify continuing relevance of and respect for this population group as "citizens" of society, of senior rank.
